Slain Texas prosecutor remembered at memorial service

TERRELL, Texas A Texas prosecutor gunned down outside his courthouse office last month was remembered Saturday for his zealousness in pursuing tough cases, love of flying and ability to tell stories.

Hundreds turned out in a school auditorium to celebrate the life of Kaufman County Assistant District Attorney Mark Hasse during a 90-minute memorial service that included stories about the veteran prosecutor's tough and softer sides as well as vows to catch his killer.

Hasse, 57, was shot multiple times the morning of Jan. 31 while walking from his car in a parking lot about a block from the courthouse. The brazen crime has sparked an investigation that includes both local and federal authorities, many of whom attended the Saturday ceremony.

Kaufman County District Attorney Mike McLelland described how Hasse, who wasn't married and had no children, never backed away from anything while often telling stories that brought laughter heard throughout the courthouse.

McLelland then turned to the effort to find Hasse's killer.

"He knows and I know there will be a reckoning," the DA said. "Too many people are focusing on that. That's not going to be a problem."

The slain prosecutor's brother, Paul Hasse, also mentioned the search for the gunman.

"You honor him by the massive effort you are making to find out who did this," he said.

Several speakers traced Hasse's career from his time as an assistant district attorney in Dallas in the 1980s to his decision three years ago to join the DA's office in Kaufman, 33 miles southeast of Dallas.

Dallas attorney Marcus Busch, who worked with Hasse in the Dallas DA's office, called Hasse "the consummate prosecutor," describing how he rose from handling cases in misdemeanor courts to being the chief of the unit charged with prosecuting organized crime. In one well-known instance, Hasse's "wicked and clever intellect" prompted him to take on a case of murder by arson that had previously been rejected, and he was able to gain a conviction, Busch said.

Busch also spoke of Hasse's love of flying and how he recovered from severe head injuries after the vintage World War II aircraft he was flying crashed in Virginia. Busch said he began taking flying lessons himself because of Hasse's passion for it.

Hasse left private practice to work as a prosecutor in Kaufman because "that's what his passion was," Busch said.

"I'd rather be in court trying a case with Mark than being in this room today," he said, stopping to gain his composure.

Cooke County DA Janice Warder, another former colleague from Hasse's Dallas days, recalled working with the prosecutor before computers put information at their fingertips. When questions would emerge from complicated autopsy reports or engineering documents, Hasse would have the answers, she said.

"Before there was Google, there was `Ask Mark,"' Warder said.

Above all else, Hasse was "ruthless when it came to fighting evil," she said.

Justin Lewis, an officer with the sheriff's department in Kaufman County who previously served as an investigator in the county DA's office, also spoke of how Hasse "enjoyed putting criminals in jail." Fighting to control his emotions, Lewis ended his remarks by saying the killer will be caught.

"Answers will eventually come," he said. "We must remain vigilant."

After Blizzard, Northeast Begins to Dig Out

The Northeast began the arduous process of cleaning up after a fierce storm swept through the region leaving behind up to three feet of snow in some areas.

By early this morning, 650,000 homes and businesses were without power and at least five deaths were being blamed on the storm: three in Canada, one in New York and one in Connecticut, The Associated Press reported.

The storm dumped snow from New Jersey to Maine, affecting more than 25 million people, with more than two feet falling in areas of Massachusetts, Rhode Island and New Hampshire. The Postal Service closed post offices and suspended mail delivery today in New England.

As the storm waned, officials in the hardest hit areas cautioned residents to remain indoors and off the roads to ease the clean-up.

Massachusetts was hard hit by the storm, with more than two feet of snow in Boston and even more in coastal areas. State police and national guard troops helped rescue more than 50 stranded motorists and even helped deliver a baby girl, according to Massachusetts Gov. Deval Patrick.

Patrick enacted the first statewide driving ban since the 1978 blizzard, which left 27 inches of snow and killed dozens. The ban was to be lifted at 4 p.m. today, the governor said.

However, Patrick cautioned residents to act with extreme caution even after the ban is over.

"Stay inside and be patient," Patrick said.

In Massachusetts a boy reportedly died of carbon monoxide poisoning as he helped his father shovel snow on Saturday, according to ABCNews.com affiliate WCVB-TV in Boston.

For residents along the coast, the waning snowfall didn't mean the end of the storm. Storm surges along the Massachusetts coastline forced some residents out of their homes Saturday morning.

"We've got 20-foot waves crashing and flooding some homes," Bob Connors on Plum Island told WCVB. "We have power and heat and all that. We just have a very angry ocean. In my 33 years, I've never seen the seas this high."

In Connecticut, Gov. Dannel Malloy declared a state of emergency and closed all roads in the state. The state police responded to more than 1,600 calls over the last 24 hours and the governor called up an additional 270 National Guard members.

"If you're not an emergency personnel that's required to be somewhere, stay home," Malloy said.

Overnight, snow fell at a rate of up to five to six inches per hour in parts of Connecticut. In Milford, more than 38 inches of snow had fallen by this morning.

In Fairfield, Conn. firefighters and police officers on the day shift were unable to make it to work, so the overnight shift remained on duty.

The wind and snow started affecting the region during the Friday night commute.

In Cumberland, Maine, the conditions led to a 19-car pile-up and in New York, hundreds of commuters were stranded on the snowy Long Island Expressway. Police and firefighters were still working to free motorists early this morning.

"The biggest problem that we're having is that people are not staying on the main portion or the middle section of the roadway and veering to the shoulders, which are not plowed," said Lt. Daniel Meyer from the Suffolk County Police Highway Patrol.

In New York, authorities are digging out hundreds of cars that got stuck overnight on the Long Island Expressway.

Bob Griffith of Syosset, N.Y., said he tried leave early to escape the storm, but instead ended up stuck in the snow by the side of the road.

"I tried to play it smart in that I started early in the day, when it was raining," said Griffith. "But the weather beat us to the punch."

Suffolk County Executive Steven Bellone said the snow had wreaked havoc on the roadways.

"I saw state plows stuck on the side of the road. I've never seen anything like this before," Bellone said.

However, some New York residents, who survived the wrath of Hurricane Sandy, were rattled by having to face another large and potentially dangerous storm system with hurricane force winds and flooding.

"How many storms of the century can you have in six months?" said Larry Racioppo, a resident of the hard hit Rockaway neighborhood in Queens, New York.

In New York, a little more than 11 inches fell in the city.

By this morning, New York Mayor Michael Bloomberg said nearly all of the primary roads had been plowed and the department of sanitation anticipated that all roads would be plowed by the end of the day.

"It looks like we dodged a bullet, but keep in mind winter is not over," said Bloomberg.

Data-wiping algorithm cleans your cellphone

Paul Marks, chief technology correspondent

Mailing your cellphone to a recycling company might make you a few pounds, but it can leave you at risk of identity theft. The deletion techniques recycling companies use are meant for hard discs, and so don't work on the solid-state flash memory used in mobile phones. That means personal data like banking info, texts, contacts and pictures can end up in the hands of, well, anyone the phone ends up with.  

To remedy the problem, British company BlackBelt Smartphone Defence of Skelmersdale, Lancashire claims to have developed a software algorithm that can securely delete data on cellphone memory chips. The trouble with data in a flash memory chip is that it is protected by an on-chip protection algorithm called the wear leveller. This hard-coded routine does its best to ensure the chip's lifetime is maximised so that each memory cell's ability to store charge is not worn out.

"The problem is that the wear-levelling algorithm ends up working
against the data wiping technique used for hard drives, which tries to
overwrite all the data,"
says the company's Ken Garner.

What the firm has done is write their own algorithm, called BlackBelt DataWipe, that works with,
rather than against, the leveller routine to render data
irrecoverable. "It is like having a shredder for personally identifiable
data," says Garner.

However, they don't yet know if their method is proof against sophisticated, nation-state level attacks - which might use electron microscopes
to read the last vestiges of the zeros and ones on a memory chip. "I imagine
if you're GCHQ you'll probably have technology that could get around
this and recover it in some way," says Garner.

Venezuela devalues currency 32% against US dollar

CARACAS: Venezuela said Friday it is devaluing its currency by 32 per cent against the dollar on the orders of cancer-stricken President Hugo Chavez, in part to trim a bloated budget deficit.

The bolivar will go from 4.3 to 6.3 to the dollar at the official exchange rate. The move was announced at a press conference by Planning and Finance Minister Jorge Giordani. He said it will take effect on Wednesday.

The goal is to "minimize expenditure and maximize results." One effect of a devaluation is to make a country's exports cheaper and thus more enticing to buyers.

But another effect is to cut the deficit, which in Venezuela last year was estimated to be nearly 10 per cent of GDP.

The economy grew 5.5 per cent last year and inflation was 20 per cent. That was down seven points from the previous year and hit the government target, but was still the highest official inflation rate in Latin America.

Venezuela is South America's largest oil exporter and has the world's largest proven reserves. Its oil transactions are dollar-denominated, so the bolivar-value of those sales will now be higher, boosting state revenues on paper.

The change had been widely expected by analysts and business leaders since last year. This is Venezuela's fifth currency devaluation in a decade.

But a side effect of the new one will be higher inflation, economists warned.

Giordani said the government would honour dollar purchase requests made before January 15 requests at the old exchange rate.

Chavez is convalescing in Cuba, where he underwent a fourth round of cancer surgery on December 11.

Vice President Nicolas Maduro, who visited Chavez this week, said at the same press conference Friday that Chavez is concerned about the Venezuelan economy and called for a "major effort" to maintain its pace of growth.

Chavez established currency controls in 2003 and the government sets the rate to curb capital flight.

But the existence of a strong black market for the dollar shows the continuing desire for hard currency.

Economist Jesus Casique warned the devaluation would have a major inflationary side effect and the government should not see it as the main tool for trimming the deficit.

Rather, it should take other steps such as clearing away red tape that makes it hard for business to obtain dollars and encouraging Venezuelan non-oil exports.

"The measure should come hand in hand with others," Casique said.

Out on the street, there was little enthusiasm for the devaluation.

"This is bad news," said businessman Jorge Martinez, walking past the Venezuelan central bank with his wife. "We have been number-crunching because in a month we are going to travel to Spain, and now we do not have enough money."

The making of a No. 1 song

Singer/songwriter Benny Blanco has produced some major hits by stars like Maroon 5, Rihanna and Ke$sha.

STORY HIGHLIGHTS

• A hit song could be a catchy earworm or a heartfelt ballad


• Top producer Benny Blanco says every song needs a hook


• Billboard expert says while albums aren't selling big, music is everywhere

(CNN) -- Don't ask music super-producer Benny Blanco to whip up a No. 1 song for an artist because it ain't gonna happen.

Sure, the man knows how to make hits: His work on Rihanna's "Diamonds" and Ke$ha's "Die Young" landed both at the top of the Billboard charts. But he's the first to tell you that trying to compose a chart topper is almost always guaranteed to fail.

"When you're like, 'Yo, we gotta write a hit song, we need a hit song right now," that never works," Blanco told CNN. "Every time that happens, I never write a hit song. I write a s****y song that sounds like someone trying to make a hit song."

Blanco knows of what he speaks. Two of the songs he helped produce are up for Grammys this year: Maroon 5's "Payphone," nominated for best pop duo or group performance, and Trey Songz's "Heart Attack," which is competing for best R&B song.

Blanco said in an era where singles rule (seriously, when was the last time you bought an entire album?) the pressure is on labels, artists and producers more than ever to produce a song that will head straight to the top of the charts.

But what does that song look and sound like? Is it an earworm such as Carly Rae Jepsen's "Call Me Maybe"? An intensely personal tale such as Adele's "Set Fire to the Rain" or a breezy "I can relate to that" poppy tune such as Taylor Swift's "We Are Never Ever Getting Back Together."

The answer is yes.

"Everything needs to be a hook," said Blanco, who snagged the Songwriter of the Year Award at the BMI Pop Awards in 2012 along with Ester Dean and Pitbull.

"Everything needs to be catchy because a listener is either going to stay with the song or lose interest in the first five seconds. But people also like those songs they can relate to and say, 'Yeah, I went through that.' "

Chris Mooney, senior director of artist promotions at TuneCore, said artists looking for a No. 1 song have to prepare their fans for a release by using every social media tool available: YouTube videos, tweets, Facebook postings, etc.

TuneCore distributes music for artists through partners such as iTunes and Spotify for a nominal fee. The company does not, he said, take a percentage of the revenue of the music distributed, and that business model has attracted such well-known acts as Nine Inch Nails, Ziggy Marley and the Civil Wars to use the service.

But if an artist wants to have a true No. 1 smash across the country, he or she will have to resort to some old-fashioned methods, Mooney said.

"You really need radio play, and that's not something everyone can do," he said. "But I still think that's key to having a No. 1 song."

That type of marketing to get airplay can be a pricey proposition. Just ask Sarah Stennett, an A&R executive and manager who works with singers Ellie Goulding and Jessie J. There are plenty of songs that are good tunes, Stennett said, but "when you've got a record that works, you need a record label that will then work that record."

But for a label to justify the expense of promoting an artist, the singer and song have to gel in a way that will connect with the audience, she said.

"There are certain songs that just encapsulate all you need to know about an artist," Stennett said. "They are like personality records. For instance, 'Get the Party Started' by Pink. It was a hit, but it also told you a great deal about who Pink was as an artist."

Stennett said the machine involved in promotion has to remain enthusiastic about the project.

"Everyone has to be about the message," she said. "It's about spreading the message. Have you heard this song by ...?"

Silvio Pietroluongo, director of charts for Billboard, said the conundrum the music industry faces is that while albums aren't selling nearly as well as before, the music is bigger than ever.

"I think music is more popular and accessible today than it's ever been," he said. "It's a major component of advertising campaigns, sporting events and anything multimedia."

That means the industry now has varying degrees of success, he said, from an artist such as Adele, whom he calls "lightning in the bottle" able to sell both singles and albums, to some such as Jepsen, who has sold millions of singles but not as many albums.

Pietroluongo said any artist is one hit away from that big break or even a comeback. But today's hit can easily come from performers such as Flo Rida, who, Pietroluongo said, is one of the all-time, top-selling digital download artists despite a lack of recognition as a hitmaker.

"They are catchy tracks," Pietroluongo said of the rapper's music. "I think the challenge with Flo Rida has been to put a face with the hits. I'm not sure if you locked 10 people in a room that half of them would realize that all the songs they love are Flo Rida."

Producer Blanco is also not easily recognizable, though he may increasingly be responsible for some of the most played music out these days. The process of putting it all together is as much fun as work, he said.

It often starts with a roomful of friends and lots of food. He likes to write with friends, he said, since as soon as he writes anything he usually shares it with them anyway. And a hit could occur while he's chilling in a hot tub or taking a walk: anything as long as the ideas keep flowing.

"I let the song come to me," he said. "Then that thing comes to you, and you just know what that thing is. Music isn't like a 9-to-5 job. You never know. It's just the most unpredictable thing."

Clamping down on prescription painkiller abuse

(CBS News) The Food and Drug Administration has called the abuse of prescription painkillers a "major public health challenge." On Friday, the FDA wrapped up a hearing on the drugs including oxycodone, Vicodin and Percocet. These painkillers do their job well -- but come with a big risk.

"My liver started shutting down," said 28-year-old Kimberly, who asked that we not use her last name. "My kidneys started shutting down. My thyroid level was through the roof."

Video: Health experts: Painkillers may cause headaches
Commonly used NSAID painkillers may be deadly for first-time heart attack sufferers

Kimberly nearly died from narcotic painkillers prescribed after a car accident. At first, she only needed one or two pills a day. But eventually she became addicted to the high.

"My tolerance started growing," she said, "and I started taking two at a time or three at a time. It grew to 15 at a time."

Kimberly is not alone. In 1999, there were about 4,000 opiate-related overdose deaths in the U.S. That figure more than quadrupled to 16,500 deaths in 2010.

"I knew that I needed to stop," Kimberly said. "I knew I did, but I couldn't bring myself to do it."

William Cope Moyers, a vice-president of the Hazelden Foundation, a drug treatment facility, said: "We are the most overly-prescribed nation in the world."

He said doctors need better education on the risks of addiction and non-narcotic options for pain treatment. Asked whether doctors are trained well enough in the management of chronic pain, Moyers said: "Clearly, doctors know the scourge of chronic pain, its legitimacy. But what they often don't know is how to deal with it with something other than writing a script."

Kimberly is in treatment at Phoenix House and has been drug-free for eight months.

"Who knows what's going to happen tomorrow? But I'll deal with that then," she said. "But today, I'm not getting high. And then tomorrow comes and I'll try the same thing."

So what are the possible solutions to the problem? The focus is on education. Patients think, 'This is a safe drug. After all, my doctor prescribed it, it's FDA-approved.' The FDA is trying to reverse that misconception. Then the White House is working to try to enact legislation so when doctors apply for that DEA registration that allows them to write the narcotics prescription, first they have to take a course that teaches them how to correctly use it.

Robot inquisition keeps witnesses on the right track

MEMORY is a strange thing. Just using the verb "smash" in a question about a car crash instead of "bump" or "hit" causes witnesses to remember higher speeds and more serious damage. Known as the misinformation effect, it is a serious problem for police trying to gather accurate accounts of a potential crime. There's a way around it, however: get a robot to ask the questions.

Cindy Bethel at Mississippi State University in Starkville and her team showed 100 "witnesses" a slide show in which a man steals money and a calculator from a drawer, under the pretext of fixing a chair. The witnesses were then split into four groups and asked about what they had seen, either by a person or by a small NAO robot, controlled in a Wizard of Oz set-up by an unseen human.

Two groups - one with a human and one a robot interviewer - were asked identical questions that introduced false information about the crime, mentioning objects that were not in the scene, then asking about them later. When posed by humans, the questions caused the witnesses' recall accuracy to drop by 40 per cent - compared with those that did not receive misinformation - as they remembered objects that were never there. But misinformation presented by the NAO robot didn't have an effect.

"It was a very big surprise," says Bethel. "They just were not affected by what the robot was saying. The scripts were identical. We even told the human interviewers to be as robotic as possible." The results will be presented at the Human-Robot Interaction conference in Tokyo next month.

Bilge Mutlu, director of the Human-Computer Interaction Laboratory at the University of Wisconsin-Madison, suggests that robots may avoid triggering the misinformation effect simply because we are not familiar with them and so do not pick up on behavioural cues, which we do with people. "We have good, strong mental models of humans, but we don't have good models of robots," he says.

The misinformation effect doesn't only effect adults; children are particularly susceptible, explains the psychologist on the project, Deborah Eakin. Bethel's ultimate goal is to use robots to help gather testimony from children, who tend to pick up on cues contained in questions. "It's a huge problem," Bethel says.

At the Starkville Police Department, a 10-minute drive from the university, officers want to use such a robotic interviewer to gather more reliable evidence from witnesses. The police work hard to avoid triggering the misinformation effect, says officer Mark Ballard, but even an investigator with the best intentions can let biases slip into the questions they ask a witness.

Children must usually be taken to a certified forensic child psychologist to be interviewed, something which can be difficult if the interviewer works in another jurisdiction. "You might eliminate that if you've got a robot that's certified for forensics investigations, and it's tough to argue that the robot brings any memories or theories with it from its background," says Ballard.

The study is "very interesting, very intriguing", says Selma Sabanovic, a roboticist at Indiana University. She is interested to see what happens as Bethel repeats the experiment with different robot shapes and sizes. She also poses a slightly darker question: "How would you design a robot to elicit the kind of information you want?"

This article appeared in print under the headline "The robot inquisition"

It's all about how you say it

When providing new information, rather than helping people recall events (see main story), a robot's rhetoric and body language can make a big difference to how well it gets its message across.

Bilge Mutlu of the University of Wisconsin-Madison had two robots compete to guide humans through a virtual city. He found that the robot which used rhetorical language drew more people to follow it. For example, the robot saying "this zoo will teach you about different parts of the world" did less well than one saying "visiting this zoo feels like travelling the world, without buying a plane ticket". The work will be presented at the Human-Robot Interaction conference in Tokyo next month.

Tennis: No Serena, no Sharapova in tweaked Fed Cup

PARIS: The 2013 Fed Cup World Group gets underway on Saturday with the tournament missing marquee names Serena Williams and Maria Sharapova and with a late format tweak aimed at boosting the event's appeal.

Both Williams and Sharapova featured in the 2012 Fed Cup, partly to meet Olympic Games qualifying criteria, but will not be involved when the United States tackle Italy and Russia welcome Japan this weekend.

Williams, who has played just six ties since 1999, has a back injury while Sharapova, whose Fed Cup record stretches to a meagre three appearances since her 2008 debut, was left out of the Russian squad.

Their absences have cut the number of players from the top 10 competing in the four World Group One ties to just three -- number seven Sara Errani of Italy, eighth-ranked Petra Kvitova of the Czech Republic and number nine Samantha Stosur of Australia.

Wary of the growing demands placed on time and physical endurance by the professional tour, the International Tennis Federation (ITF) announced on Thursday changes concerning dead rubbers in the tournament.

Under the new policy, if a tie is decided after the third singles rubber, the fourth singles rubber will not be played and the dead doubles rubber will be played instead.

However if the tie is only decided after the fourth singles rubber, the dead doubles rubber will still be played with a match tiebreak (first to 10 points) replacing the third set.

"The enhancement of the dead rubber policy came in response to requests from players, captains and National Associations following its successful introduction in Davis Cup," said ITF executive vice-president Juan Margets.

"This is part of the ITF's continued effort to make Fed Cup more player friendly, while maintaining a good spectator experience on the Sunday."

Former Wimbledon champion Kvitova leads defending champions Czech Republic against Australia in Ostrava where she will be playing her 14th Fed Cup tie since 2007.

However, she has struggled this season, a shock second round exit at the Australian Open followed by a quarter-final loss in Paris last week where she was second seed.

"My results are not exactly what I want them to be, but I still believe it will be OK. I know I can play tennis, and I like Fed Cup," said the 22-year-old.

In the absence of the Williams sisters, as well as Australian Open semi-finalist Sloane Stephens, the 17-time champions US will be led by world number 21 Varvara Lepchencko when they face Italy in Rimini.

Italy, with Errani and world number 16 Roberta Vinci likely to play singles and doubles, beat the US in the 2009 and 2010 finals.

Even without Sharapova, Russia, the four-time winners, should be too strong for Japan in Moscow.

Maria Kirilenko, at 13, Ekaterina Makarova, the world number 20, Anastasia Pavlyuchenkova, the 31st-ranked player and number 32 Elena Vesnina, are all higher up the WTA pecking order than Japan's top singles player Ayumi Morita, the world 57.

In Nis, 2012 runners-up Serbia, who are likely to be without world number 14 and former French Open champion Ana Ivanovic with a shoulder injury, tackle Slovakia.

Alleged cop killer: I have no family, 'I'm terminating yours'

STORY HIGHLIGHTS

• Police believe former cop Christopher Jordan Dorner shot three officers, killing one


• This was days after he allegedly killed two people, one a retired LAPD officer's daughter


• In an 11-page manifesto, Dorner promises "war" on police and their families


• The suspect's truck is found burnt in a mountainous area 100 miles east of L.A.

Los Angeles (CNN) -- A former Los Angeles cop with military training vowed war against other men in blue Thursday, leaving one officer dead days after he allegedly killed two other people to begin a wave of retribution for being fired, police said.

The focus of the intensive, expansive manhunt is Christopher Jordan Dorner, a 270-pound former Navy lieutenant who has professed his venom against LAPD officers he claimed ruined his life by forcing him out of his dream job.

Dorner blames one retired officer for bungling his appeal to get his job back in an 11-page manifesto, in which he also complained of mistreatment by the LAPD. In that letter -- provided to CNN by an LAPD source -- he vowed to wage a war targeting police officers and their families, whoever and wherever they are.

"I will bring unconventional and asymmetrical warfare to those in LAPD uniform whether on or off duty," Dorner wrote.

"I never had the opportunity to have a family of my own, I'm terminating yours."

Authorities believe he followed through on his threats early Thursday by shooting a Riverside, California, police officer and two others. A day earlier, Irvine police named Dorner a suspect in the double slayings Sunday of a woman -- identified by Los Angeles police as the daughter of a retired LAPD officer -- and her fiance.

"My opinion of the suspect is unprintable," said Riverside police Chief Sergio Diaz, hours after one of his officers was killed. "The manifesto, I think, speaks for itself (as) evidence of a depraved and abandoned mind and heart."

The violence, as well as Dorner's background as a police officer and expert marksman, left police on edge around Southern California.

In Torrance, LAPD officers guarding one of Dorner's alleged targets mistakenly opened fire on a blue pickup truck that resembled one Dorner was thought to be driving, said Los Angeles police Chief Charlie Beck.

The gunfire left two people wounded, Beck said. Torrance police also fired on another blue pickup, but no one was injured in that incident, according to a senior law enforcement source.

In downtown Los Angeles, police wearing body armor patrolled outside their own iconic headquarters.

Police have good reason to be fearful, the chief said.

"Of course, he knows what he's doing. We trained him," Beck said. "He was also a member of the armed forces. It is extremely worrisome and scary, especially to the officers involved."

The manhunt for Dorner spanned hundreds of miles and numerous counties. By Thursday afternoon, it was largely centered around Big Bear Lake -- about 100 miles east of Los Angeles -- where authorities found the truck the suspect allegedly used in the Riverside shooting.

Police confirmed that the vehicle, which was burnt out when it was found, belonged to Dorner by its vehicle identification number, San Bernardino County Sheriff John McMahon said.

This discovery spurred more officers to converge on the area to conduct beefed up patrols, staff checkpoints and go to every residence in the mountain community. McMahon acknowledged it is possible the fire was set as a diversionary tactic, though law enforcement isn't taking any changes.

"He could be anywhere at this point, and that's why we're searching door to door," the sheriff said.

1 cop dies in 'cowardly ambush'

It all started Sunday when Dorner allegedly killed two people in Irvine, according to police.

Police identified the victims as Monica Quan and her fiance Keith Lawrence.

Quan, 27, was the daughter of retired Los Angeles police Officer Randal Quan, LAPD Officer Tenesha Dobine told CNN. In his manifesto, Dorner said Quan handled his appeal.

On Tuesday, Dorner checked into the Navy Gateway Inns and Suites on San Diego's large naval base, Cmdr. Brad Fagan said.

Dorner likely had access to the hotel because he'd been honorably discharged from the Navy Reserve, said the Navy spokesman. Having retired February 1 as a lieutenant, Dorner worked with mobile inshore undersea warfare units and provided security on oil platforms in Iraq, according to Pentagon records. He was rated as a rifle marksman and pistol expert.

"He did not physically check out" Wednesday as expected, Fagan told reporters.

Police in San Diego say a man who could have been Dorner tried to hijack a boat there on Wednesday. Someone later found a wallet containing Dorner's identification and an LAPD detective's badge near the San Diego airport, according to police. It was unclear whether the badge was legitimate.

By about 1 a.m. Thursday, the scene had shifted about 100 miles north to Corona, California.

There, a pair of LAPD officers on a protection detail were flagged down by a citizen who reported seeing the suspect's vehicle, LAPD Deputy Chief Jose Perez said.

The officers chased the vehicle and caught up to it on an Interstate 15 off-ramp.

"The officers were fired upon with a shoulder weapon," Perez said, with one of them suffering a "graze wound" to his head. The police returned fire, while the suspect set off once again.

About 20 minutes later, two police officers were in their car at a stop light in Riverside when Dorner allegedly pulled up beside them.

That driver unleashed "multiple rounds" from a rifle at the officers, riddling the cop car with bullets and leaving a 34-year-old officer, who had been on the Riverside force for 11 years, dead, according to Diaz. The other officer, 27, was "seriously wounded but we expect a full recovery," the Riverside police chief said.

It was "a cowardly ambush," said Diaz, claiming Dorner has "no connection" to his city.

A good Samaritan picked up one of their police radios and called dispatchers to send help, Riverside police said.

In addition to posting his manifesto online, Dorner reached out directly to CNN, mailing a parcel to AC360 anchor Anderson Cooper's office at CNN in New York.

The package arrived on February 1 and was opened by Cooper's assistant. Inside was a hand-labeled DVD, accompanied by a yellow Post-it note reading, in part, "I never lied" -- apparently in reference to his 2008 dismissal from the LAPD.

The package also contained a coin wrapped in duct tape. The tape bears the hand-written inscription: "Thanks, but no thanks, Will Bratton." It also had letters that may be read as "IMOA", which could be a commonly used Internet abbreviation for "Imagine a More Open America," or "1 MOA," or perhaps one minute of angle, implying he was notably accurate with a firearm.

The coin is a souvenir medallion from former LAPD Chief William Bratton, of a type often given out as keepsakes. This one, though, was shot through with bullet holes: three bullet holes to the center and another shot nicked off the top.

The editorial staff of AC360 and CNN management were made aware of the package Thursday. Upon learning of its existence, they alerted Bratton and law enforcement.

Bratton headed the LAPD at the time Dorner was dismissed.

Dorner challenged his firing for years, losing at every turn. First, the police department's Board of Rights rejected his appeal. Then, in October 2011, a judge ruled against his appeal, according to court records.

Beck, the Los Angeles police chief, said Thursday that Dorner's case had been "thoroughly reviewed" and said the department would not apologize to Dorner or clear his name.

But as his manifesto shows, Dorner is showing no sign of relenting.

He complained he had been railroaded out of the department after reporting police brutality by another officer. Dorner also complained of a continuing culture of racism and brutality in the LAPD.

Attacks on other police officers and their families, he said, are "a necessary evil that I do not enjoy but must partake and complete for substantial change to occur within the LAPD and reclaim my name."

"Look your wives/husbands and surviving children directly in the face and tell them the truth as to why your children are dead," Dorner wrote.

Such a chilling warning prompted Los Angeles police to set up 40 protective details in an effort to safeguard people listed in Dorner's letter, Beck said.

The chief acknowledged that this effort was taxing the department, which has been placed under tactical alert, meaning all officers must stay on duty.

"It's extremely, extremely manpower intensive," Beck said. "But the safety of my employees, people that come on the job to protect the lives of strangers, is extremely important to me. And I will expend whatever resource is necessary."

Despite adoption ban, N.J. couple brings home Russian tot

(CBS News) FREEHOLD, N.J. -- It's been about a month since Russian President Vladimir Putin banned Americans from adopting Russian children. It was widely seen as a retaliation for a new U.S. law targeting Russians who have violated human rights. At the time, 1,000 American families were in the middle of the adoption process.

CBS News first met Robert and Kim Summers a month ago. They were just weeks away from picking up their new son Preston from a Russian orphanage, when Putin announced the ban.

"I cannot put into words how my wife and I feel right now," Robert said at the time. "And we ask Putin, please, consider alternate means, but don't let these children suffer. Please. That's all we ask."

Despite the ban, the Summers decided to travel to Russia. They weren't sure whether they would return to the U.S. with their child.

"We did not know. We just prayed and kept the faith and just kept believing that, you know, all of our efforts would pay off," said Kim.

It was mid-January when they visited Preston in his orphanage outside Moscow. They finalized his paperwork and went to pick up his passport at a Russian government office.

"She looked at it and she said in Russian, 'Americans? I thought there was a ban on Americans. How could we give them this passport?'" Kim recalled.

"We held our breath and I gasped for air and I said, oh no. Please, don't let us go through all this and we're going to have problems," Robert said.

The Summers returned the next day and found out the ban did not apply to them because a judge had already signed off on their adoption before the law was passed.

Five days later, they left Russia and brought Preston home.

"Robert and I looked at each other and we said, it's over, it's over. And I can't even tell you the relief. And how elated we are," said Kim. "I completely understand when a mother says that she takes one look at her newborn child and is instantly in love with that child. I'm in love with him. I'm in love with him, and I do believe he's in love with us, too."

The State Department estimates just 50 American families, whose adoptions have been approved by judges, will be allowed to leave Russia with their new children. The Summers consider themselves blessed to be among them.
