South Korea unveils missile it says can hit North's leaders

SEOUL (Reuters) - South Korea unveiled a cruise missile on Thursday that it said can hit the office of North Korea's leaders, trying to address concerns that it is technologically behind its unpredictable rival which this week conducted its third nuclear test.

South Korean officials declined to say the exact range of the missile but said it could hit targets anywhere in North Korea.

The Defence Ministry released video footage of the missiles being launched from destroyers and submarines striking mock targets. The weapon was previewed in April last year and officials said deployment was now complete.

"The cruise missile being unveiled today is a precision-guided weapon that can identify and strike the window of the office of North Korea's leadership," ministry spokesman Kim Min-seok told reporters.

North Korea has forged ahead with long-range missile development, successfully launching a rocket in December that put a satellite into orbit.

The North's ultimate aim, Washington believes, is to design an intercontinental ballistic missile capable of carrying a nuclear warhead that could hit the United States.

North Korea, which accuses the United States and its "puppet", South Korea, of war-mongering on an almost daily basis, is likely to respond angrily to South Korea flexing its muscles.

North Korea, technically still at war with the South after their 1950-53 conflict ended in a truce, not a peace treaty, carried out its third nuclear test on Tuesday, drawing condemnation from around the world including its only major ally China.

The test and the threat of more unspecified actions from Pyongyang have raised tensions on the Korean peninsula as the South prepares to inaugurate a new president on February 25.

"The situation prevailing on the Korean peninsula at present is so serious that even a slight accidental case may lead to an all-out war which can disturb the whole region," North Korea's official KCNA news agency said.

Third Japanese dies after Guam tourist attack

HAGATNA: The death toll from a frenzied attack on Japanese tourists in the Pacific nation of Guam rose to three on Thursday when a man mowed down by the killer's car succumbed to his injuries, officials said.

The attack happened late on Tuesday when a local man drove his car up a pavement near a resort, injuring six, then went on a stabbing rampage after crashing into a convenience store, wounding another eight.

All 14 victims, including an eight-month-old baby and a three-year-old toddler, were Japanese.

The Guam Memorial Hospital said the third person to die was a 51-year-old man but refused to give further details, saying next of kin in Japan were still being notified.

Two women, named in court documents as 81-year-old Kazuko Uehara and Rie Sugiyama, 29, were stabbed to death in the attack, which has stunned the normally sleepy tropical tourist destination.

The hospital said six people were discharged on Thursday and one had been transferred to Japan, with four patients still receiving care at the facility.

Local man Chad Ryan Desoto, 21, was charged over the attack on Wednesday.

Prosecutors allege that after he was arrested Desoto admitted to police that he was intent on using both his car and his knife to hurt as many people as possible.

Desoto's motive for the attack remains unknown.

Researchers develop a more accurate car navigation system

Researchers say new navigation system can be installed on any vehicle, including a Volkswagen Touareg.

Driverless cars could get a big boost from a new system that researchers say will increase the accuracy of in-car satellite navigation systems by 90 percent.

Researchers say the system combines conventional GPS signals with data from sensors such as accelerometers and gyroscopes to determine a vehicle's position within six feet of its location, a dramatic reduction from the current margin of error of 50 feet. The system can be installed inexpensively in any vehicle, say researchers at Spain's Universidad Carlos III de Madrid, where the system was developed.

"We have managed to improve the determination of a vehicle's position in critical cases by between 50 and 90 percent, depending on the degree of the signals' degradation and the time that is affecting the degradation on the GPS receiver," David Martín, a researcher at the Systems Intelligence Laboratory, said in a statement describing the project.

The system aims to tackle the greatest challenge faced by conventional GPS systems in urban settings: loss or disruption of satellite signal due to interference created by buildings, trees, and tunnels. The new system uses contextual information and an algorithm that eliminates deviations caused by degradation or loss of signal from satellites.

The researchers have installed a prototype system on an "intelligent
car" with the goal of capturing and interpreting all the information available while driving a car. The team sees applications of the system in driverless car systems currently under development by Google and a handful of automakers.

"Future applications that will benefit from the technology that we are currently working on will include cooperative driving, automatic maneuvers for the safety of pedestrians, autonomous vehicles or cooperative collision warning systems," the team said.

Ultimately, the team hopes to develop a system that harnesses the sensors built in to smartphones, such an accelerometer, a gyroscope, a magnetometer, and GPS, as well as taking advantage of communications tools such as Wi-Fi, Bluetooth, and GSM.

Couple: "Calm" Dorner tied us up in our condo

LOS ANGELES A California couple says fugitive ex-police officer Christopher Dorner tied them up in their mountain condominium and stole their car before the firefight that led to his presumed death.

Karen and Jim Reynolds said at a news conference Wednesday that they came upon Dorner when they entered the condo in Big Bear, Calif. Tuesday, and believe he'd been there as early as Friday.

They say Dorner had a gun but said he wouldn't hurt them.

CBS Los Angeles station KCBS-TV reports Karen said, "He talked to us. Tried to calm us down. And saying very frequently he would not kill us."

"He was very calm and very methodical," said Karen.

Authorities couldn't immediately verify their story, but it matched early reports from law enforcement officials. Later reports said the incident involved two women from a cleaning crew.

The Reynolds said they went to the cabin noon to clean it for rental purposes, and that's when they -- and not two cleaning ladies as had been reported - met up with Dorner, KCBS says.

The Reynolds say he tied their arms and put pillowcases over their heads before fleeing in their Nissan.

Karen Reynolds managed to get to her cell phone and dial 911.

The couple, who said Dorner had his gun drawn the entire time, said they were with the suspect for 15 minutes, KCBS adds. "It felt like a lot longer," said Karen. "I really thought that it was the end."

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.

U.S. says to take lead to contain North Korea

SEOUL (Reuters) - U.S. President Barack Obama said North Korea's third nuclear test, in defiance of U.N. resolutions, was a threat and a provocation and that the United States would lead the world in responding.

North Korea has said Tuesday's test was an act of self-defense against "U.S. hostility" and threatened stronger steps if necessary.

"Provocations of the sort we saw last night will only isolate them further, as we stand by our allies, strengthen our own missile defense, and lead the world in taking firm action in response to these threats," Obama said in his State of the Union address, delivered 24 hours after the North's test.

North Korea tested nuclear devices in 2006 and 2009. But despite the three tests and a long-range rocket launch, it is not believed to be close to manufacturing a nuclear missile capable of targeting the United States.

But Washington believes the isolated state's ultimate aim is to design an intercontinental ballistic missile capable of carrying a nuclear warhead that could reach the continental United States. North Korea says its rocket program is aimed at putting satellites in space.

The latest test has drawn condemnation from around the world, including from China which for years has been the North's only major ally.

The U.N. Security Council held an emergency meeting at which its members, including China, "strongly condemned" the test and vowed to start work on appropriate measures in response, the president of the council said.

North Korean leader Kim Jong-un, the third member of his family to rule, has presided over two long-range rocket launches and a nuclear test during his first year in power, pursuing policies that have propelled his impoverished and malnourished country closer to becoming a nuclear weapons power.

North Korea said the test had "greater explosive force" than those in 2006 and 2009. Its KCNA news agency said it had used a "miniaturised" and lighter nuclear device, indicating it had again used plutonium, which is suitable for use as a missile warhead.

EXASPERATED

China, which has shown signs of increasing exasperation with the recent bellicose tone of its reclusive neighbor, summoned the North Korean ambassador in Beijing and protested sternly, the Chinese Foreign Ministry said.

Foreign Minister Yang Jiechi said China was "strongly dissatisfied and resolutely opposed" to the test and urged North Korea to "stop any rhetoric or acts that could worsen situations and return to the right course of dialogue and consultation as soon as possible".

Analysts said the test was a major embarrassment to China, which is a permanent member of the Security Council and North Korea's sole major economic and diplomatic ally.

Obama said the test would be a setback for North Korea's economic development.

"The regime in North Korea must know that they will only achieve security and prosperity by meeting their international obligations," he said.

U.S. ambassador to the United Nations Susan Rice said Washington and its allies intended to "augment the sanctions regime" already in place due to Pyongyang's previous atomic tests. North Korea is already one of the most heavily sanctioned states in the world and has few external economic links that can be targeted.

Japanese Prime Minister Shinzo Abe said the test was a "grave threat" that could not be tolerated.

Russian Foreign Minister Sergei Lavrov urged North Korea to abandon its nuclear arms program and return to talks. NATO condemned the test as an "irresponsible act."

South Korea, still technically at war with North Korea after a 1950-53 civil war ended in a truce, also denounced the test. Obama spoke to South Korean President Lee Myung-bak on Tuesday and told him the United States "remains steadfast in its defense commitments" to South Korea, the White House said.

MAXIMUM RESTRAINT

North Korea's Foreign Ministry said the test was "only the first response we took with maximum restraint".

"If the United States continues to come out with hostility and complicates the situation, we will be forced to take stronger, second and third responses in consecutive steps," it said in a statement carried by the KCNA news agency.

North Korea - which gave the U.S. State Department advance warning of the test - often threatens the United States and its "puppet", South Korea, with destruction in colourful terms.

North Korea told the U.N. disarmament forum in Geneva that it would never bow to resolutions on its nuclear program and that prospects were "gloomy" for the denuclearization of the divided Korean peninsula because of a "hostile" U.S. policy.

The magnitude of the explosion was roughly twice that of the 2009 test, according to the Vienna-based Comprehensive Nuclear-Test Ban Treaty Organization.

U.S. intelligence agencies were analyzing the event and found that North Korea probably conducted an underground nuclear explosion with a yield of "approximately several kilotons", the Office of the Director of National Intelligence said.

Nuclear experts have described the previous two tests as puny by international standards. The yield of the 2006 test has been estimated at less than 1 kiloton (1,000 tons of TNT equivalent) and the second at some 2-7 kilotons, compared with 20 kilotons for a Nagasaki-type bomb.

Initial indications are that the test involved the latest version of a plutonium-based prototype weapon, according to one current and one former U.S. national security official. Both previous tests involved plutonium. If it turns out the test was of a new uranium-based weapon, it would show that North Korea had made more progress on uranium enrichment than previously thought.

"VICIOUS CYCLE"

When Kim Jong-un, who is 30, took power after his father's death in December 2011, there were hopes that he would bring reforms and end Kim Jong-il's "military first" policies.

Instead, North Korea, whose economy is smaller than it was 20 years ago and where a third of children are believed to be malnourished, appears to be trapped in a cycle of sanctions followed by further defiance.

"The more North Korea shoots missiles, launches satellites or conducts nuclear tests, the more the U.N. Security Council will impose new and more severe sanctions," said Shen Dingli, a professor at Shanghai's Fudan University.

"It is an endless, vicious cycle."

Options for a response from the international community appear to be few. Diplomats at the United Nations said negotiations on new sanctions could take weeks since China is likely to resist tough new measures for fear they could lead to further retaliation by the North Korean leadership.

Significantly, the test comes at a time of political transition in China, Japan and South Korea, and as Obama begins his second term.

The North's longer-term game plan may be to restart international talks aimed at winning food and financial aid. China urged it to return to the stalled "six-party" talks on its nuclear programme, hosted by China and including the two Koreas, the United States, Japan and Russia.

16 gunmen killed in Thai military base attack: army

NARATHIWAT, Thailand: In one of the most deadly attacks in Thailand's long-running insurgency, scores of heavily-armed gunmen stormed a southern army base on Wednesday, leaving 16 militants dead, authorities said.

In the unusually brazen early-morning assault, 100 militants, dressed in army fatigues and armed with AK47 and M16 assault rifles, attacked the unit in Narathiwat province, unit commander Captain Somkiat Pholprayoon said.

"Sixteen militants were confirmed dead after the attack," he told reporters at the scene, adding that the military and police were in "hot pursuit" of the 60 to 70 militants who fled the base after the attack.

The government expressed sorrow over the deaths, one of the highest single death tolls in some eight years of violence in Thailand's deep south, but praised the military operation, saying the army have had no choice.

"The government has no policy of using violence to deal with southern unrest but in this incident (militants) attacked the military base," Deputy Prime Minister Chalerm Yubamrung told reporters in Bangkok.

A shadowy insurgency has been fighting for greater autonomy for the country's southernmost provinces since 2004, with shootings and bombings occurring on a near-daily basis.

More than 5,500 people have been killed, both Buddhist and Muslim, in the bloody conflict.

Chalerm, who heads the government's special body in charge of the southern unrest, recently proposed imposing a curfew in certain areas of the most affected provinces.

"If we impose a curfew, then militants will find it more difficult to enter the area," he said on Wednesday.

Religious leaders oppose the move, saying it will do nothing to solve the underlying problems. The Thai cabinet is set to discuss the proposal on Friday.

Critics accuse the government of failing to address the grievances of Thailand's Malay Muslim minority, including alleged abuses by the military and a perceived lack of respect for their ethnic identity, language and religion.

Members of Thailand's security forces are frequently targeted in ambushes and roadside bombs, but organised attacks on military bases are relatively rare.

No military casualties were reported in the early hours assault at the base in the Bacho district of Narathiwat province, one of three Muslim-dominated provinces near the border with Malaysia. An army spokesman had earlier put the militants' death toll at 17.

"We learned of the attack in advance from defected militants," Colonel Pramote Promin, southern army spokesman told Thai television.

He added that a key local leader of the fighters, who wore bulletproof vests during the attack, had been killed in the clashes.

Southern army commander Lieutenant General Udomchai Thammasarorat called for local villagers to stay in their homes for 24-hours, for their "safety and to prevent any confusion during the pursuit of militants", he told broadcaster Thai PBS.

A report by the International Crisis Group on the violence in December said insurgents had grown "bolder and stronger" amid political inaction from successive Bangkok governments.

The attack on Wednesday is "part of a trend" towards bigger, bolder attacks by militants showing a new "willingness on the part of militants to engage the security forces head on," said Matthew Wheeler, an ICG South East Asia analyst.

"The fact that so many militants were killed is very unusual," he said, adding the last time there was such a high death toll was in April 2004.

The ICG report recommended a greater push towards decentralisation and closer engagement with local civil society groups and peace negotiations with insurgents.

It added that the deployment of 60,000 security forces and an emergency decree "have not achieved any appreciable decline in casualties".

Opera embraces WebKit in browser brain transplant

Opera Software, an independent voice in the browser market since the 1990s, will dramatically change its strategy by instead adopting the WebKit browser engine used by Safari and Chrome.

The Norwegian company announced the move today and said it will show off the first fruits of the work with a WebKit-based version of its
Android browser at the Mobile World Congress show in less than two weeks. But the company will move to WebKit for its desktop browser, too.

A browser engine processes the Web page instructions written in HTML, JavaScript, and CSS then renders the results on screens. The engine also interactions that are increasingly important as the developer world expands from static Web pages to dynamic Web apps.

Opera Chief Technology Officer Hakon Wium Lie described the company's motives in a statement:

The WebKit engine is already very good, and we aim to take part in making it even better. It supports the standards we care about, and it has the performance we need. It makes more sense to have our experts working with the open source communities to further improve WebKit and Chromium, rather than developing our own rendering engine further. Opera will contribute to the WebKit and Chromium projects, and we have already submitted our first set of patches: to improve multi-column layout.

Hints of Opera's WebKit work emerged with a mobile-browser project called ICE in January, but today's news is a much more sweeping change than just a single product. Opera said it will move gradually to the WebKit for "most of its upcoming versions of browsers for smartphones and computers." It's not immediately clear which products will continue to use Opera's in-house technology.

Opera has struggled to keep its fifth-place ranking in the browser usage, but it's certainly not irrelevant. The company also announced today that 300 million people use its browsers each month.

But there are difficult trends the company must face. On mobile devices, Opera Mini is a strong contender, but its popularity is chiefly on lower-end phones; iOS and Android devices come with their own WebKit-based browsers. On personal computers, Google's Chrome rose from nowhere in a few years, quickly surpassing Opera and
Safari, while Microsoft by some measures has reversed declines in its share of browser usage.

The WebKit project began as the KHTML engine used in the KDE project to supply Linux with a polished user interface and a host of software utilities, but Apple became its chief sponsor when it based OS X's WebKit on the project. WebKit got another major boost with Google's embrace.

One notable consequence of moving to WebKit is that Opera will be able to more easily support the large and growing number of iOS devices. Apple rules prohibit browser engines besides a version of WebKit that Apple itself supplies (and incidentally, that runs slower than the version Safari on iOS itself uses). Google's Chrome for iOS uses this Apple-supplied version of WebKit, and Opera would be able to make such a move more easily if its own browser used WebKit, too.

WebKit is not a single, unified project, though. For example, Chrome and Safari differ dramatically under the covers in how they execute the JavaScript programs on Web pages. Chrome uses Google's V8 JavaScript engine, whereas Safari uses a different one called Nitro. It's not clear which Opera will use.

Another consequence of Opera's change is that developers could have an easier time supporting browsers. Although independent testing will still be required, Web pages likely will be easier to write and test -- especially advanced ones using newer features such as animations and "responsive" design that can handle a wide variety of screen types.

With Opera throwing in the towel on its own technology, the bulk of the browser market will be reduced to three primary engines: WebKit, Microsoft's Trident, and Mozilla's Gecko.

Not surprisingly, House GOP pans State of the Union

Obama: Both parties know sequester cuts "a really bad idea"

It shouldn't come as a shock that congressional Republicans weren't very impressed by President Obama's State of the Union address. 

For his part, the president didn't hide his suggestion that it's Republicans who are resistant to compromise, leading some Republicans to jab the president, particularly regarding his lack of clarity on how he would replace the so-called sequester cuts set to slash defense and domestic spending on March 1.

"What has he done?" asked Rep. Cory Gardner, R-Colo. "He signed the sequester, he agreed to the sequester, he came up with the sequester and then he complains about House solutions to actually try to deal with it. This president is more interested in campaign-style rhetoric than actual solutions."

While many said there is some room to work with Mr. Obama on issues like immigration, and even some gun safety measures, his new proposals on everything from education to repairing the nation's crumbling bridges were panned not necessarily based on merit, but on the president's claim that the new programs would not increase the deficit "by a single dime."

"I think it doesn't pass the laugh test" said the chairman of the conservative House Republican Study group Rep. Steve Scalise, R-La. "People realize the President promised to cut the deficit in half and it's more than doubled."

"It's economic fairy dust that this President's working with," added Gardner.

On the president's call to address climate change and become more energy independent, Rep. Lee Terry, R-Neb., called the president's silence on giving the green light to construct the Keystone XL pipeline to pump oil from Canada to the Gulf of Mexico "deafening."

Chairman of the House Energy and Commerce Committee Fred Upton, R-Mich., also said "With a stroke of the pen, the president could unleash this $7 billion private sector investment. Yet nowhere in this evening's blueprint for the president's policy vision was this critical middle-class jobs project."

Rep. Raul Labrador, R-Idaho, who is expected to be a key House Republican player in immigration talks as a Hispanic-American from a conservative state, said the president's State of the Union this year was "one of the least inspiring speeches I ever heard him give."

But Labrador said he does think Republicans and Democrats will ultimately be able to come together on an overhaul of the nation's immigration system.

"As long as the president and his party don't draw a red line and say that they have to get everything that they want."

Labrador was less optimistic about gun control. He compared his home state of Idaho with low crime and few gun regulations to Mr. Obama's home state of Illinois as an example of why gun laws aren't necessarily effective.

"It has the most stringent gun control legislation and it has some of the highest crime in the United States" Labrador said of Illinois. "Clearly gun control is not going to protect those families."

And while Labrador said he believes the president cares about the victims of gun violence and their families that attended the speech, he said they should not be used as "political pawns."

Labrador said, however, that as a father of five children he was so upset by the Sandy Hook Elementary School massacre that he could not speak of the shooting for two days. He said "if there's things that we can do to save lives without violating the second amendment I think we should consider it."

Democrats gave the speech high marks. In a statement, Minority Leader Nancy Pelosi, D-Calif., said she urged the two parties to work together and said "it is time to heed the President's call for real progress to reverse the rising tide of climate change, enact comprehensive immigration reform, and prevent gun violence."

Charred Human Remains Found in Burned Cabin

Investigators have located charred human remains in the burned out cabin where they believe suspected cop killer and ex-LAPD officer Christopher Dorner was holed up as the structure burned to the ground, police said.

The human remains were found within the debris of the burned cabin and identification will be attempted through forensic means, the San Bernardino County Sheriff-Coroner Department said in a press release early this morning.

Dorner barricaded himself in the cabin in the San Bernardino Mountains near Big Bear Tuesday afternoon after engaging in a gunfight with police, killing one officer and injuring another, the San Bernardino County Sheriff's Department said.

Cindy Bachman, spokeswoman for the San Bernardino County Sheriff's Department, which is the lead agency in the action, said Tuesday night investigators would remain at the site all night.

FULL COVERAGE: Christopher Dorner Manhunt

When Bachman was asked if police thought Dorner was in still in the burning cabin, she said, "Right… We believe that the person that barricaded himself inside the cabin engaged in gunfire with our deputies and other law enforcement officers is still inside there, even though the building burned."

Bachman spoke shortly after the Los Angeles Police Department denied earlier reports that a body was found in the cabin, contradicting what law enforcement sources told ABC News and other news organizations.

Fugitive Ex-Cop Believed Barricaded in Cabin, California Cops Say Watch Video

Police around the cabin told ABC News they saw Dorner enter but never leave the building as it was consumed by flames, creating a billowing column of black smoke seen for miles.

A press conference is scheduled for later today in San Bernardino.

One sheriff's deputy was killed in a shootout with Dorner earlier Tuesday afternoon, believed to be his fourth and victim after killing an LAPD officer and two other people this month, including the daughter of a former police captain, and promising to kill many more in an online manifesto.

Cops said they heard a single gunshot go off from inside the cabin just as they began to see smoke and fire. Later they heard the sound of more gunshots, the sound of ammunition being ignited by the heat of the blaze, law enforcement officials said.

Police did not enter the building, but exchanged fire with Dorner and shot tear gas into the building.

One of the largest dragnets in recent history, which led police to follow clues across the West and into Mexico, apparently ended just miles from where Dorner's trail went cold last week.

Police got a break at 12:20 p.m. PT, when they received a 911 call that a suspect resembling Dorner had broken into a home in the Big Bear area, taken two hostages and stolen a car.

The two hostages, who were tied up by Dorner but later escaped, were evaluated by paramedics and were determined to be uninjured.

Officials say Dorner crashed the stolen vehicle and fled on foot to the cabin where he barricaded himself and exchanged fire with deputies from the San Bernardino Sheriff's Office and state Fish and Game officers.

Two deputies were wounded in the firefight and airlifted to a nearby hospital, where one died, police said. The second deputy was in surgery and was expected to survive, police said.

Police sealed all the roads into the area, preventing cars from entering the area and searching all of those on the way out. Are schools were briefly placed on lockdown.
