How safe are nanoparticles in food?

STORY HIGHLIGHTS

• Andy Behar: Some foods contain tiny, engineered particles called nanomaterials


• Behar: Nanoparticles might pose health risks, since they have adversely affected mice


• He says not enough studies have adequately demonstrated the safety of nanoparticles


• Behar: With an emerging technology such as this, companies have to be careful

Editor's note: Andy Behar is the chief executive of As You Sow, a nonprofit organization that promotes corporate accountability.

(CNN) -- Some foods sold in supermarkets across America contain tiny, engineered particles called nanomaterials. Our organization decided to test doughnuts after learning that the titanium dioxide used as a coloring in the powdered sugar coating likely contained nano-sized particles.

The tests, conducted by an independent laboratory, found that both Dunkin' Donuts Powdered Cake Donuts and Hostess Donettes did indeed contain titanium dioxide nanoparticles. In response, a spokeswoman for Dunkin Donuts said the company was looking into the matter.

You must be wondering: What are nanomaterials? They are microscopic in size. "If a nanoparticle were the size of a football, a red blood cell would be the size of the field." Nanoparticles have been heralded as having the potential to revolutionize the food industry -- from enabling the production of creamy liquids that contain no fat, to enhancing flavors, improving supplement delivery, providing brighter colors, keeping food fresh longer, or indicating when it spoils.

But there are a few problems.

One is that no one knows how many and which food products have them. Companies are not being forthcoming about whether they are using nanoparticles. To further complicate the issue, some companies may not even be aware that they are selling products containing them.

Many companies are reluctant or uninterested in discussing the issue, and concrete information has been difficult to obtain. The majority of food companies are not responsive in providing information about their specific uses, plans and policies toward nanoparticles. There is also no law in the United States that requires disclosure. In contrast, companies in the European Union are required to label foods containing nanoparticles.

The bigger issue with nanoparticles is that they might pose health risks, as they have been found to in tests on mice.

There are not nearly enough studies that can adequately demonstrate the safety of nanoparticles in food additives or packaging. Scientists are still investigating how the broad range of nanoparticles, with their myriad potential uses, would react in the body.

When ingested, nano-sized particles can pass into the blood and lymph, where they circulate through the body and reach in potentially sensitive sites such as bone marrow, lymph nodes, the spleen, the brain, the liver and the heart.

Our knowledge about how nanomaterial food additives react in the body and their health impact is still in its infancy. While efforts are under way to understand them better, much deeper scientific inquiry should occur before nanoparticles are sold in food and food-related products.

More companies and consumers need to be aware of the use of engineered nanomaterials in foods and the potential unknown risks of this technology. More food products like M&M's and Pop-Tarts should be tested as recent studies have identified them as likely to contain nanomaterials as well.

Fortunately, a few companies have become willing to take a public position on nanoparticles.

McDonald stated that it "does not currently support the use by suppliers of nano-engineered materials in the production of any of our food, packaging, and toys." Similarly, Kraft Foods said that it was not using nanotechnology.

Some of the largest food companies in the world, including YUM! Brands, PepsiCo, and Whole Foods, need to know more about nanomaterials and check with their supplies to see if they are using them.

Americans are becoming increasingly interested in what is in the food they're eating. No longer content with label information on daily allowances of vitamins and minerals, U.S. consumers are following the lead of their counterparts in many other countries by demanding more disclosure about where and how their food is grown and whether it is safe.

Even though communicating risks to consumers can be challenging, the public's perception of safety will be paramount in determining the acceptance of nanomaterials. This is especially true for an emerging food-products technology the safety of which even the FDA has acknowledged a lack of understanding.

Researchers collaborate on system to extend battery lifespan in devices

SINGAPORE: Researchers from Singapore and the US are collaborating to come up with a system that can extend the lifespan of batteries in devices such as laptops and smartphones.

The Institute of Microelectronics (IME) and Stanford University will work to advance innovations in nano-electromechanical systems (NEMS).

NEMS technology is known for its higher energy efficiency.

The system has the ability to stamp out leakage currents that occur during passive standby mode in electronic devices.

Leakage current is one of the leading sources of power consumption in digital systems, using traditional semiconductor switches.

By replacing these traditional switches with NEMS switches, the total power consumption of a digital block can be reduced by up to 10 times.

Dr Lee Jae Wung, the IME Scientist leading the project, said: "One of the challenges in building a reliable NEMS switch is in achieving Thin Film Encapsulation to protect the switch structure and the contact materials from degradation and oxidation by providing proper vacuum condition and/or filling inert gas inside the cavity. IME's capabilities in back end of line compatible materials and processes are expected to contribute strongly in this area."

"NEMS relay has proven to be an effective complement to conventional Si CMOS technology for reducing power consumption. The collaboration with IME will advance this device technology to a manufacturing process that is suitable for co-integration with Si CMOS in practical applications," said Professor Philip Wong, Willard R. and Inez Kerr Professor in the School of Engineering at Stanford University.

The Institute of Microelectronics (IME) is a research institute of the Science and Engineering Research Council of the Agency for Science, Technology and Research (A*STAR).

Body in burned cabin ID'd as Christopher Dorner

(CBS News) BIG BEAR LAKE, Calif. - Remains of a man who was in a burned California cabin on Tuesday have been positively identified as belonging to that of Christopher Dorner, the former LAPD officer who was suspected of killing four people and was the subject of an intense manhunt, officials confirmed.

The San Bernardino County Coroner's office said the positive identification was made through dental records.

The final hours of the manhunt for Christopher Dorner began when Jim and Karen Reynolds opened the door of one of their rental condos.

Police fill in the blanks on Dorner's last day
Carjacking victim: Christopher Dorner told me "I don't want to hurt you"
Deputy slain in ex-cop shootout was new father

"We had come into the living room and he opened the door and came out at us," said Karen.

"He had the gun drawn," added Jim.

A man believed to be Dorner tied them up.

"He talked to us, trying to calm us down," said Karen, "and saying very frequently he would not kill us."

He then took their car. "We listened for probably a minute or two, wanted to make sure he was gone," said Jim, "sounded quiet. And then we started struggling trying to get loose."

They called 911, triggering a chain of events that ended with Tuesday's shootout in which two sheriffs deputies were shot. Thirty-five-year-old Jeremiah MacKay died from his wounds.

The firefight that we witnessed was intense and we were forced to take cover - however, we left his cell phone on. Early in the standoff you could hear officers suggesting burning the suspect out.

One officer can be heard saying, "Burn that ------ out , burn it down, ------ burn this mother-----"

Four more hours would pass before police used high-powered tear gas. The canisters are known to be a fire hazard.

"We did not intentionally burn down that cabin to get Mr. Dorner out," San Bernandino Sheriff John McMahon had said.

Dorner's body was found in the ashes. It's unclear if the cause of death was from the fire -- or a single shot we heard moments after the cabin ignited.

Meanwhile, investigators looking through a trash bin in Irvine, California, where the first two victims were killed, recovered Dorner's badge, a police uniform, and a high-capacity ammo magazine.

CBS News asked San Bernardino County Sheriff's Department about the audio we recorded, and they declined to comment.

Dorner Confirmed Dead in Autopsy on Cabin Remains

Christopher Dorner, the ex-Los Angeles police officer who declared himself on a killing spree against his former law enforcement colleagues, is dead.

Authorities this evening confirmed that remains found after a fiery standoff at a California mountain cabin Tuesday were, in fact, Dorner's.

"The charred human remains located in the burned out cabin in Seven Oaks have been positively identified to be that of Christopher Dorner," the San Bernardino County Sheriff-Coroner's Office said in a written statement. "During the autopsy, positive identification was made through dental examination."

In a 6,000-word "manifesto," Dorner outlined his anger at the Los Angeles Police Department for firing him, and made threats against individuals he believed were responsible for ending his career with the police force five years ago. Dorner was fired after filing what the LAPD determined to be a false report accusing other cops of brutality.

Dorner is suspected of killing four people, including Monica Quan and her fiance, who were found shot to death Feb. 3. Quan was the daughter of former LAPD Capt. Randal Quan, who was mentioned as a target of Dorner's fury in the manifesto.

Christopher Dorner Believed Dead After Shootout With Police Watch Video

Dorner is also suspected in the shooting death of Riverside, Calif., Police Officer Michael Crain, whose funeral was Wednesday.

San Bernardino Sheriff's Deputy Jeremiah MacKay, 35, a 15-year veteran and the father of two children, was killed in Tuesday's shootout at the cabin.

A second San Bernardino County sheriff's officer had to undergo multiple surgeries after he was wounded in the cabin shootout, and other officers also were wounded in earlier alleged encounters with Dorner.

After Crain's death, police tracked Dorner to the Big Bear Lake area of Southern California, where his burning truck was found in the mountains late last week.

A couple with a cabin in the area were some of the last people to see Dorner before his final encounter with police. Their 911 call to police triggered a chase that concluded with the fiery standoff at the nearby cabin.

The couple, Karen and Jim Reynolds, said at a news conference Wednesday that their ordeal lasted a few minutes but seemed like hours.

The Reynolds believe Dorner, 33, was holed up starting Friday in their unoccupied cabin in Big Bear, Calif., only steps from where police had set up a command center.

"He said four or five times that he didn't have a problem with us, he just wanted to clear his name," Jim Reynolds said. "He said, 'I don't have a problem with you, so I'm not going to hurt you.'"

Dorner tied their arms and put pillowcases over their heads before fleeing in their purple Nissan, the couple said.

Before he fled, the couple said Dorner told them that he had been watching them before he took over their cabin. Dorner told the couple he could tell they were "hard working, good people."

"He had been watching us and saw me shoveling the snow Friday," Jim Reynolds said.

They say they may have left the cabin door unlocked and that could have been the reason Dorner was able to enter undetected.

Dorner remained "calm and meticulous" throughout the harrowing ordeal, the couple said.

The Reynolds walked into their cabin around noon Tuesday when they came face-to-face with Dorner. There was no question in their minds who he was -- the suspected cop killer at the center of one of the largest manhunts in recent memory.

Mom of boy held in bunker is worried

STORY HIGHLIGHTS

• Phil McGraw speaks with mother of former Alabama child hostage


• She tells him she worried about trying to put him back on a school bus


• Ethan told her the Army killed the 'bad man'


• The 6-year-old tells his mom that 'My bus driver is dead'

(CNN) -- Jennifer Kirkland says she caught her 6-year-old son Ethan just staring at a school bus the other day.

He was mesmerized, his eyes locked on the yellow vehicle. He didn't say a thing, and she didn't know what to say to him.

The last time he was on a bus, he was sitting just behind the driver -- as he always did -- waiting for his stop so he could go home.

But the "bad man" got on, and killed the driver, his buddy Mr. Poland.

Appearing on the "Dr. Phil" show, Kirkland told Phil McGraw she was worried how her little boy was going to react the next time she tried to put him on the bus to school.

After being kidnapped, the recovery ahead

Photos: Alabama bunker standoff

HIDE CAPTION

Ethan has been having a hard time sleeping, she told the psychologist turned syndicated daytime talk show host.

He thrashes his arms, tosses and turns and sometimes he calls out.

It has only been almost 10 days since the FBI sent a rescue team into the bunker in Midland City, Alabama, where Ethan was held hostage for nearly a week by Jimmy Lee Dykes.

His mother hasn't asked Ethan what happened when he was there.

"I have not talked to Ethan about it," she said in an interview aired Wednesday. "I don't know how to. As a mother I want him to know that I'm there if he needs to talk. I don't know how to respond because I have never been through this."

Inside the bunker: From storm shelter to boy's prison

Ethan has seen two people shot to death. Dykes shot bus driver Charles Poland several times before he carried Ethan, who had fainted, off the bus and into an underground bunker Dykes had built on his property.

Then the FBI killed Dykes when negotiations broke down and authorities felt they had to rescue the boy before Dykes, who had a handgun, did something rash.

"The Army came in and shot the bad man," Kirkland said Ethan told her.

Kirkland said she had hoped Dykes wouldn't be harmed.

"From the very beginning, I had already forgiven Mr. Dykes even though he had my child," she said. "I could not be angry through this. My job was to be the mother."

She thinks Dykes had a soft spot for Ethan because he has disabilities. Dykes took care of her boy as best he could, she said.

He even fried chicken for the boy.

Still, as the crisis continued, she worried that Dykes might be spooked by something her child did -- or that he had enough supplies to stay down there for months. She worried her boy would think she had abandoned him.

She asked authorities to let her speak to Dykes.

"That's my baby. He's my world. He's my everything," she said. "Everything I do I do for him. And I was afraid I wasn't going to get him back."

When she did get him back, he was in the hospital, putting stickers on everyone in sight.

"Hey, bug, I sure have missed you," she recounted.

"I missed you, too," he answered.

FBI: Bombs found in Alabama kidnapper's bunker

Now she worries that even though he seems like the same playful little boy, there is an emotional storm ahead.

McGraw told her to talk to Ethan about his feelings, not what happened to him in the bunker.

"Let that decay in his young mind," he said.

McGraw asked Ethan a few questions, but as 6-year-olds are apt to do, he answered most with a "Yes" or a "No."

But when the doctor asked him how he got to school, Ethan said, "On my bus, but my ..."

Then he walked over to his mother and as if telling a secret, whispered in her ear, "But my bus driver is dead."

Kirkland told McGraw that it was Poland who helped Ethan conquer his fear of descending the steep school bus steps. Poland would cheer Ethan on and one day when the child hesitated and the mother went to help, the driver said, "Let him do it."

Since then, Ethan has had no problem.

But now his cheerleader won't be there, and Kirkland is anguished about her boy.

"Mr. Poland put him behind him so he could keep a good eye on him," she said.

Ethan hasn't been back to school yet. He's been busy opening birthday presents and playing with his favorite toys. On Wednesday, he made a new friend in Gov. Robert Bentley.

There's a picture from the event where little Ethan is sitting underneath the governor's desk. The child is beaming.

"Ethan is a loving, forgiving child," Kirkland said. "He is easy to go up to a perfect stranger and say, 'Can I have a hug?'"

That was the boy who went into that bunker. She is concerned it's not the child who came out.

Obama speech 'relied on amnesia'

STORY HIGHLIGHTS

• Matt Welch: State of the Union featured content-free calls to action for action's sake


• He says governed might want to know what they've gotten in return for ballooning debt


• Didn't we try repairing infrastructure with the stimulus package? he asks


• Welch: Rand Paul spoke to those who think government should get out of way

Editor's note: Matt Welch is editor in chief of Reason and co-author of "The Declaration of Independents: How Libertarian Politics Can Fix What's Wrong With America" (Public Affairs).

(CNN) -- The two most memorable lines of President Barack Obama's fourth State of the Union address were the ad-libbed: "Get it done" (which doesn't appear in the remarks as prepared), and the emotional "They deserve a vote," concerning victims of gun violence.

As exasperated appeals for an obstructionist Congress to get off its duff, the exhortations provided emotional catnip for Democrats. For the rest of us, however, they were sobering reminders of what governing liberalism has deteriorated into: content-free calls to take action for action's sake.

Consumers of national governance are within their rights to ask just what we've gotten in return for ballooning the cost of the stuff since 2000. The answer may lie in not just what the president said, but what he has assumed we've already forgotten.

Matt Welch

"Let's cut in half the energy wasted by our homes and businesses over the next 20 years," said the president, who promised a "Recovery Through Retrofit" three years ago. "The American people deserve a tax code that ... lowers tax rates for businesses and manufacturers that create jobs right here in America," said the man who before he took office vowed to, uh, give "tax breaks to companies that are investing here in the United States."

That "aging infrastructure badly in need of repair"? Well, what happened to the $50 billion from the stimulus package dedicated to precisely that task, or the $50 billion plan 18 months later? Making college "more affordable"? That has been the motivation for continuous ratcheting of government involvement in higher education, which has -- surprise! -- coincided with a several-decade increase in tuition costs and student loan debt.

Greene: In 2013, democracy talks back

Do-something politics works when Americans have amnesia, or are reacting to headline-making tragedies, or when they just want free stuff. But this irresistible force is butting up against the immovable object of a have-nothing U.S. Treasury. Debt service costs will soon overtake defense spending, and baby boomer entitlements are about to transform the federal government into a check-writing program for senior citizens.

Americans know by now that Obama can't possibly believe his own promises that his policies won't "increase our deficit by a single dime," not only because of his poor track record with that particular vow, but because he spends the rest of his time talking about all the various things the government needs to "invest" to create "broad-based growth." It's a conflict at the basic level of vision with those of us who think prosperity is mostly a private-sector affair that is on balance imperiled, not improved, by the exertions of a deficit-spending government.

Opinion: Obama dares Congress to get the job done

Thankfully, and quite unlike during the 2012 presidential campaign, the competing vision was voiced Tuesday night. Not necessarily by a dehydrated but game Sen. Marco Rubio, R-Florida, who delivered the Republican response to the State of the Union address, but by Sen. Rand Paul, R-Kentucky, who did the honors online for the tea party.

"The path we are on is not sustainable," Paul said, directly. "All that we are, all that we wish to be, is now threatened by the notion that you can have something for nothing, that you can have your cake and eat it, too, that you can spend a trillion dollars every year that you don't have."

Paul dinged Republicans as well as Democrats, targeted military spending as well as entitlements, and spent a good 30 seconds giving a more full-throated defense of wartime civil liberties than the allegedly anti-war candidate Obama ever did.

Most importantly, he laid out a truly alternative vision that speaks directly to the growing number of Americans who feel like the federal government has failed as the engine of economic growth, and needs urgently to take a back seat before it does more harm.

Rothkopf: This time, a president in full

"What America needs," Paul said, "is not Robin Hood, but Adam Smith." As Obamanomics continues underperforming through a second term, it will be fascinating to see whether Ron Paul's kid can get more people to agree.

Papal 'cohabitation' poses unique Vatican challenge

VATICAN CITY: The Roman Catholic Church faces a unique challenge starting next month when a living former pope begins a "cohabitation" with his successor, both residing in the world's tiniest sovereign state, Vatican City.

The Vatican insists that the German pope, who stunned the world by announcing that he will retire on February 28, wants to keep a low profile in retirement.

"He will live at the Vatican in total discretion," Vatican spokesman Federico Lombardi said Wednesday. "His presence will in no way be an impediment, interference or a problem."

Nevertheless, Lombardi said the octogenarian's presence would be felt and "appreciated", and did not rule out an advisory role for the future pensioner, whose title has yet to be determined but may be Bishop of Rome Emeritus.

"If his successor wants advice from him he will be totally free to provide it... (but) this would in no way be required" of the former pope, Lombardi said.

Others in the Vatican are more nervous about the unprecedented situation.

Rino Fisichella, head of the Vatican department for the new evangelisation, said the former pope may eventually have to live elsewhere.

The Vatican on Wednesday denied an Internet rumour that the pope would take up permanent residence in the Abbey of Monte Cassino -- a famous monastery that was destroyed in World War II and rebuilt.

The cerebral former theology professor, who will turn 86 in April, is a prolific writer. He is currently completing a work on faith that started out as an encyclical but will have to be published as a book given Benedict's imminent abdication.

He is also expected to spend more time with his beloved cats and playing Beethoven and Mozart compositions on his piano.

An early signal of Benedict's intention to go quietly is his plan to leave the Vatican the day he steps aside, slipping away to the summer papal residence of Castel Gondolfo outside Rome.

The Vatican has been unable to say how long he will stay there, but has stressed he will not have any role in the Conclave of Cardinals that is to elect his successor in the third week of March -- in time for Easter at the end of the month.

His absence will allow workers to prepare the papal apartments in the Apostolic Palace for the new pontiff -- and complete renovations of the living quarters for the soon-to-be ex-pope in a former nunnery at the Vatican.

Benedict's choice not to return to his native Bavaria should surprise no one given that he has now lived in Rome for nearly four decades.

The little-known Mater Ecclesiae convent where he will reside was established by the pope's predecessor John Paul II to house cloistered nuns.

Their departure last November, two years earlier than expected, raised few eyebrows at the time but is now cited as one of a series of clues that presaged the pope's shock announcement, according to astute Vatican watchers.

The disused convent is an oasis of calm with its own gardens producing rare roses -- one of them named after John Paul II -- as well as vegetables and citrus fruit.

The peppers, tomatoes, courgettes and cabbages grown in the vegetable garden traditionally supply the papal kitchen.

Spread over three floors, the modern complex has 12 monastic cells upstairs, while the ground floor houses a kitchen, living room, library and chapel.

The cells are sparsely furnished: the only decorations to be seen are wooden crosses and a few paintings depicting scenes from religious life, according to the Vatican.

In retirement, Benedict is to revert to his birth name Joseph Ratzinger -- but canon law experts are looking into whether he can reclaim his status as a cardinal, or whether the new pope can make him a cardinal once again.

Asked if the pope would receive a pension, Lombardi hesitated but said the pope would not go hungry.

"We will ensure he can live a dignified existence," Lombardi said.

Some traditions usually observed at the death of a pope will be observed, notably the destruction of the Fisherman's Ring used to place the papal seal on official Church documents.

"It's an unprecedented situation, we'll see how it goes," Lombardi said.

Source: American, US Airways merger approved

Updated 8:13 PM ET

(MoneyWatch) A source told CBS News that the boards of American Airlines and US Airways (LCC) have approved a merger that would create the world's biggest carrier.

Under the deal, which is expected to be unveiled Thursday if the timeline isn't moved up sooner and there are no last-minute snags, the combined airline would keep the "American" name. It would still require federal approval, although that is virtually ensured. US Air CEO Doug Parker is expected to lead the combined company.

A merger of US Air and American would surpass a 2010 tie-up between United Airlines (UAL) and Continental and a 2008 deal joining Delta (DAL) and Northwest. The merged American would be the largest carrier and sport a market valuation of roughly $10 billion.

Although airlines tout such consolidation as a way to cut costs and expand service amid intense competition, whether industry mergers raise fares is an open question. Many analysts say yes because reduced competition in any business often results in higher prices. One study found that ticket prices went up more than 20 percent between Detroit and Atlanta after Delta bought Northwest. Fares went up more than 30 percent on routes between Chicago and Houston, as well as Newark to San Francisco, after the United-Continental deal.

In seeking to run more efficiently, merging airlines also often cut capacity and eliminate routes.

American close to merger with U.S. Airways

Other analysts are more optimistic about the potential benefits to travelers. They say the three largest U.S. airlines still must compete with discount carriers such as Southwest (LUV), which has flourished for years by offering low-cost flights and no-frills service.

The consolidation trend is largely blamed on the price of fuel. Oil now costs so much more per barrel than it did 10 years ago that one analyst says the margin of profit on many flights has shrunk to the value of a single seat. That means an airline can lose money if it flies with one single empty middle seat. The days of elbow room are over.

American Airlines has been operating under court supervision since declaring bankruptcy in November 2011.

Dorner Not IDed, But Manhunt Considered Over

Though they have not yet identified burned remains found at the scene of Tuesday's fiery, armed standoff, San Bernardino, Calif., officials consider the manhunt over for Christopher Dorner, the fugitive ex-cop accused of going on a killing spree.

"The events that occurred yesterday in the Big Bear area brought to close an extensive manhunt," San Bernardino County Sheriff John McMahon told reporters this evening.

"I cannot absolutely, positively confirm it was him," he added.

However, he noted the physical description of the suspect authorities pursued to a cabin at the standoff scene, as well as the suspect's behavior during the chase and standoff, matched Dorner, 33.

The charred remains of the body believed to be Dorner were removed from the cabin high in the San Bernardino Mountains near Big Bear, Calif., the apparent site of Dorner's last stand. Cornered inside the mountain cabin Tuesday, the suspect shot at cops, killing one deputy and wounding another, before the building was consumed by flames.

"We did not intentionally burn down that cabin to get Mr. Dorner out," McMahon said tonight, though he noted pyrotechnic canisters known as "burners" were fired into the cabin during a tear gas assault in an effort to flush out Dorner. The canisters generate high temperatures, he added.

The deputies wounded in the firefight were airlifted to a nearby hospital, where one died, police said.

The deceased deputy was identified tonight as Det. Jeremiah MacKay, 35, a 15-year veteran and the father of two children -- a daughter, 7, and son, 4 months old.

"Our department is grieving from this event," McMahon said. "It is a terrible deal for all of us."

The Associated Press quoted MacKay on the Dorner dragnet Tuesday, noting that he had been on patrol since 5 a.m. Saturday.

"This one you just never know if the guy's going to pop out, or where he's going to pop out," MacKay said. "We're hoping this comes to a close without more casualties. The best thing would be for him to give up."

The wounded deputy, identified as Alex Collins, was undergoing multiple surgeries for his wounds at a hospital, McMahon said, but was expected to make a full recovery.

Before the final standoff, Dorner was apparently holed up in a snow-covered cabin in the California mountains just steps from where police had set up a command post and held press conferences during a five-day manhunt.

The manhunt for Dorner, one of the biggest in recent memory, led police to follow clues across the West and into Mexico, but it ended just miles from where Dorner's trail went cold last week.

Residents of the area were relieved today that after a week of heightened police presence and fear that Dorner was likely dead.

"I'm glad no one else can get hurt and they caught him. I'm happy they caught the bad guy," said Ashley King, a waitress in the nearby town of Angelus Oaks, Calif.

Hundreds of cops scoured the mountains near Big Bear, a resort area in Southern California, since last Thursday using bloodhounds and thermal-imaging technology mounted to helicopters, in the search for Dorner. The former police officer and Navy marksman was suspected to be the person who killed a cop and cop's daughter and issued a "manifesto" declaring he was bent on revenge and pledging to kill dozens of LAPD cops and their family members.

But it now appears that Dorner never left the area, and may have hid out in an unoccupied cabin just steps from where cops had set up a command center.
