American and US Airways Are Expected to Announce Merger This Week

After months of negotiations, American Airlines and US Airways are expected this week to announce a merger, which would create the nation’s biggest airline and concentrate even further a once-fragmented industry.

A merger would expand American’s domestic network, particularly in the Northeast and the Southwest, and create a more formidable competitor internationally. The combined airline would jump ahead of United Airlines and Delta Air Lines, both of which have grown through mergers of their own in recent years.

The combination would probably bring to an end the wave of consolidation that has swept the industry. Since 2001 there have been five large mergers, reducing the number of airlines to three main carriers, along with a handful of low-cost carriers like Southwest Airlines and JetBlue, and regional carriers.

These mergers have led to cuts in service to many smaller cities around the country. But they have also created healthier and more profitable airlines that are able to invest in new planes and products. Faced with rising fuel costs, and losing tens of billions of dollars in the last decade, airline executives argued that the only way to survive was to consolidate capacity.

American, which has been in bankruptcy protection since November 2011, is currently the nation’s third-largest airline with domestic and international flights; US Airways is the fourth.

The boards of both carriers are expected to meet on Monday to approve the combination, which then needs to be approved by a bankruptcy judge in New York. A tie-up also requires the approval of federal regulators and antitrust authorities. But analysts expect regulators to approve the deal since there is little overlap between the two networks and no hubs in the same cities.

Even if the deal clears all these hurdles, the merged airline still faces a range of challenges. Airline mergers are often rocky — involving complex technological systems, big reservation networks as well as large labor groups with different corporate cultures that all need to be combined seamlessly. United angered passengers last year after a series of merger-related computer and reservation mistakes, and late and delayed flights.

A deal would be a major victory for Doug Parker, the chairman of US Airways, who began pursuing a merger with the bigger carrier soon after American filed for bankruptcy. His argument — that American could succeed against bigger airlines only if it combined networks with US Airways — swayed American’s creditors who have a critical say in the company’s future.

The carriers have been discussing a deal for months. In recent days, both sides have moved much closer but were still trying to figure out how much the merged carrier would be worth and how management positions would be split.

Tom Horton, American’s chairman, who was opposed to a merger for much of the last year, was offered a position as nonexecutive chairman, said a person familiar with the matter but who asked not to be identified because the talks were still under way. US Airways shareholders could end up with about 28 percent of the new airline, and American’s creditors would have 72, this person said.

A merger could be structured to take effect as American exits bankruptcy. The airlines are pushing for a deal before Feb. 15, when some nondisclosure agreements with American bondholders are set to expire.

The new airline will be called American Airlines and based in Dallas. It will have a combined 94,000 employees, 950 planes, 6,500 daily flights, nine major hubs, and total sales of nearly $39 billion. It would be the market leader on the East Coast, the Southwest and South America. But it would remain a smaller player in the Pacific and Europe, where United and Delta are stronger.

Mr. Parker deftly outmaneuvered Mr. Horton by lobbying American’s employees. He gained an important edge last April when he won the public support of American’s three main labor groups. More recently, pilots from both airlines agreed on how they would work together if the merger succeeded.

The success of these labor discussions, even before the merger was formally discussed, helped persuade American’s creditors to follow Mr. Parker’s strategy.

Mr. Horton, and American’s management team, had argued that they should complete the carrier’s reorganization and emerge from bankruptcy as an independent airline before considering any mergers.

But under pressure from Mr. Parker, the management of American Airlines was eventually forced by its creditors to talk to Mr. Parker about a merger. All that was left then was to figure out who was going to lead the merged airline and how much it would be worth.

Mr. Parker, more than anyone in the business, knows the difficulty of integrating two airlines. In 2005, he orchestrated the merger of the airline he was then running, America West, with a larger carrier, US Airways. But pilots from each of these two original airline have yet to agree to a common contract and seniority rules, and, to this day, cannot fly together.

The difficulty is likely to be compounded at American. In bankruptcy, American cut thousands of jobs, reduced benefits, froze pensions, and sought higher productivity rules from its employees.

Before the US Airways-American deal, the last major combination was the acquisition of AirTran by Southwest, completed in 2011. That followed the merger of United and Continental Airlines in 2010, which created the current leader, and before that Delta with Northwest.

American has major hubs in Dallas, Miami, Chicago, Los Angeles and New York. But it has been steadily losing ground to its rivals over the last decade while racking up losses that have totaled more than $12 billion in over 10 years.

US Airways has hubs in Phoenix, Philadelphia and Charlotte, and has a big presence at Washington’s National Airport.

Its shareholders will have to vote on the proposed merger.

A delicate new balancing act in senior healthcare

When Claire Gordon arrived at Cedars-Sinai Medical Center, nurses knew she needed extra attention.

She was 96, had heart disease and a history of falls. Now she had pneumonia and the flu. A team of Cedars specialists converged on her case to ensure that a bad situation did not turn worse and that she didn't end up with a lengthy, costly hospital stay.

Frail seniors like Gordon account for a disproportionate share of healthcare expenditures because they are frequently hospitalized and often land in intensive care units or are readmitted soon after being released. Now the federal health reform law is driving sweeping changes in how hospitals treat a rapidly growing number of elderly patients.

The U.S. population is aging quickly: People older than 65 are expected to make up nearly 20% of it by 2030. Linda P. Fried, dean of the Columbia University Mailman School of Public Health, said now is the time to train professionals and test efforts to improve care and lower healthcare costs for elderly patients.

"It's incredibly important that we prepare for being in a society where there are a lot of older people," she said. "We have to do this type of experiment right now."

At Cedars-Sinai, where more than half the patients in the medical and surgical wards are 65 or older, one such effort is dubbed the "frailty project." Within 24 hours, nurses assess elderly patients for their risk of complications such as falls, bed sores and delirium. Then a nurse, social worker, pharmacist and physician assess the most vulnerable patients and make an action plan to help them.

The Cedars project stands out nationally because medical professionals are working together to identify high-risk patients at the front end of their hospitalizations to prevent problems at the back end, said Herb Schultz, regional director of the U.S. Department of Health and Human Services.

"For seniors, it is better care, it is high-quality care and it is peace of mind," he said.

The effort and others like it also have the potential to reduce healthcare costs by cutting preventable medical errors and readmissions, Schultz said. The federal law penalizes hospitals for both.

Gordon, an articulate woman with brightly painted fingernails and a sense of humor, arrived at Cedars-Sinai by ambulance on a Monday.

Soon, nurse Jacquelyn Maxton was at her bedside asking a series of questions to check for problems with sleep, diet and confusion. The answers led to Gordon's designation as a frail patient. The next day, the project team huddled down the hall and addressed her risks one by one. Medical staff would treat the flu and pneumonia while at the same time addressing underlying health issues that could extend Gordon's stay and slow her recovery, both in the hospital and after going home.

To reduce the chance of falls, nurses placed a yellow band on her wrist that read "fall risk" and ensured that she didn't get up on her own. To prevent bed sores, they got her up and moving as often as possible. To cut down on confusion, they reminded Gordon frequently where she was and made sure she got uninterrupted sleep. Medical staff also stopped a few unnecessary medications that Gordon had been prescribed before her admission, including a heavy narcotic and a sleeping pill.

"It is really a holistic approach to the patient, not just to the disease that they are in here for," said Glenn D. Braunstein, the hospital's vice president for clinical innovation.

Previously, nurse Ivy Dimalanta said, she and her colleagues provided similar care but on a much more random basis. Under the project, the care has become standardized.

The healthcare system has not been well designed to address the needs of seniors who may have had a lifetime of health problems, said Mary Naylor, gerontology professor at the University of Pennsylvania School of Nursing. As a result, patients sometimes fall through the cracks and return to hospitals again and again.

"That is not good for them and that is not good for society to be using resources in that way," Naylor said.

Using data from related projects, Cedars began a pilot program in 2011 and expanded it last summer. The research is continuing but early results suggest that the interventions are leading to fewer seniors being admitted to the intensive care unit and to shorter hospital stays, said Jeff Borenstein, researcher and lead clinician on the frailty project. "It definitely seems to be going in the right direction," he said.

The hospital is now working with Naylor and the University of Pennsylvania to design a program to help the patients once they go home.

"People who are frail are very vulnerable when they leave the hospital," said Harriet Udin Aronow, a researcher at Cedars. "We want to promote them being safe at home and continuing to recover."

In Gordon's case, she lives alone with the help of her children and a caregiver. The hospital didn't want her experiencing complications that would lengthen the stay, but they also didn't want to discharge her before she was ready. Under the health reform law, hospitals face penalties if patients come back too soon after being released.

Patients and their families often are unaware of the additional attention. Sitting in a chair in front of a vase of pink flowers, Gordon said she knew she would have to do her part to get out of the hospital quickly. "You have to move," she said. "I know you get bed sores if you stay in bed."

Gordon said she was comfortable at the hospital but she wanted to go back to her house as quickly as she could. "There's no place like home," she said.

Two days later, that's where she was.

DC Comics Turns the Occupy Movement Into a Superhero Title

Eighteen months after the phrase first entered the collective public consciousness, the plight of the 99 percent is coming to mainstream superhero comics — via a new series from the second biggest publisher in the American comic industry, which just happens to be a subsidiary of a multi-national corporation that makes around $12 billion a year. Irony, anybody?

In May, DC Comics will launch two new series taking place in their mainstream superhero universe that offer different insights into the class struggle in a world filled with superheroes, alien races and inexplicable events. The Green Team, written by Tiny Titans and Superman Family Adventures creators Art Baltazar and Franco, with art by Ig Guara, revives an obscure 1975 concept about teenage rich kids who try to make the world a better place with their outrageous wealth. In an interview promoting the series, Franco promised that it would address questions like “Can money make you happy?” and “If you had unlimited wealth, could you use that to make the lives of people better?”

Obviously, this is one of the more fanciful series DC will be publishing.

But while DC is promoting The Green Team series as the adventures of the “1%,” its companion title, The Movement, is teased as a chance for us to “Meet the 99%… They were the super-powered disenfranchised — now they’re the voice of the people!”

“It’s a book about power,” explained The Movement writer Gail Simone. “Who owns it, who uses it, who suffers from its abuse. As we increasingly move to an age where information is currency, you get these situations where a single viral video can cost a previously unassailable corporation billions, or can upset the power balance of entire governments. And because the sources of that information are so dispersed and nameless, it’s nearly impossible to shut it all down.”

“The thing I find fascinating and a little bit worrisome is, what happens when a hacktivist group whose politics you find completely repulsive has this same kind of power and influence,” she elaborated in an interview at Big Shiny Robot. “What if a racist or homophobic group rises up and organizes in the same manner?”

While the concept is ambitious, the idea that a comic capable of living up to the book’s populist inspiration could come from DC Entertainment still strikes some as unlikely. Matt Pizzolo, the editor of the Occupy Comics anthology, told Wired that “though DC Comics did help launch Alan Moore and David Lloyd’s seminal anarchist epic V For Vendetta over two decades ago, it’s unlikely they would do so today. Between dismantling Vertigo and frankensteining Watchmen, the past year has demonstrated DC isn’t a safe place for bold creators who want to tell the kinds of stories that would inspire things like Occupy, rather than just cash in on them.”

Still, Simone says that the use of the iconography and language of a real-world populist movement is deliberate, promising that the book will reflect today’s decentralized political world and offer ”a slice of rarity that we’re unlikely to see in most superhero books.”

This wouldn’t the first time that DC has attempted to offer pre-packaged populist rebellion, of course; in addition to the aforementioned publication of the anti-establishment V For Vendetta, the company’s Vertigo imprint also published Grant Morrison’s The Invisibles, a series centering around an international organization struggling against forces of authority and repression that included anti-corporate themes.

Only time will tell whether The Movement will live up to the subversive examples of these earlier books, or just end up a well-intentioned piece of topical super heroics that trades on, and commodifies, a real political movement.

The Movement #1 will be available in both print and digital formats on May 1, while The Green Team #1 will be released on May 22.

In Nigeria, Polio Vaccine Workers Are Killed by Gunmen

At least nine polio immunization workers were shot to death in northern Nigeria on Friday by gunmen who attacked two clinics, officials said.

The killings, with eerie echoes of attacks that killed nine female polio workers in Pakistan in December, represented another serious setback for the global effort to eradicate polio.

Most of the victims were women and were shot in the back of the head, local reports said.

A four-day vaccination drive had just ended in Kano State, where the killings took place, and the vaccinators were in a “mop-up” phase, looking for children who had been missed, said Sarah Crowe, a spokeswoman for the United Nations Children’s Fund, one of the agencies running the eradication campaign.

Dr. Mohammad Ali Pate, Nigeria’s minister of state for health, said in a telephone interview that it was not entirely clear whether the gunmen were specifically targeting polio workers or just attacking the health centers where vaccinators happened to be gathering early in the morning. “Health workers are soft targets,” he said.

No one immediately took responsibility, but suspicion fell on Boko Haram, a militant Islamist group that has attacked police stations, government offices and even a religious leader’s convoy.

Polio, which once paralyzed millions of children, is now down to fewer than 1,000 known cases around the world, and is endemic in only three countries: Nigeria, Pakistan and Afghanistan.

Since September — when a new polio operations center was opened in the capital and Nigeria’s president, Goodluck Jonathan, appointed a special adviser for polio — the country had been improving, said Dr. Bruce Aylward, chief of polio eradication for the World Health Organization. There have been no new cases since Dec. 3.

While vaccinators have not previously been killed in the country, there is a long history of Nigerian Muslims shunning the vaccine.

Ten years ago, immunization was suspended for 11 months as local governors waited for local scientists to investigate rumors that it caused AIDS or was a Western plot to sterilize Muslim girls. That hiatus let cases spread across Africa. The Nigerian strain of the virus even reached Saudi Arabia when a Nigerian child living in hills outside Mecca was paralyzed.

Heidi Larson, an anthropologist at the London School of Hygiene and Tropical Medicine who tracks vaccine issues, said the newest killings “are kind of mimicking what’s going on in Pakistan, and I feel it’s very much prompted by that.”

In a roundabout way, the C.I.A. has been blamed for the Pakistan killings. In its effort to track Osama bin Laden, the agency paid a Pakistani doctor to seek entry to Bin Laden’s compound on the pretext of vaccinating the children — presumably to get DNA samples as evidence that it was the right family. That enraged some Taliban factions in Pakistan, which outlawed vaccination in their areas and threatened vaccinators.

Nigerian police officials said the first shootings were of eight workers early in the morning at a clinic in the Tarauni neighborhood of Kano, the state capital; two or three died. A survivor said the two gunmen then set fire to a curtain, locked the doors and left.

“We summoned our courage and broke the door because we realized they wanted to burn us alive,” the survivor said from her bed at Aminu Kano Teaching Hospital.

About an hour later, six men on three-wheeled motorcycles stormed a clinic in the Haye neighborhood, a few miles away. They killed seven women waiting to collect vaccine.

Ten years ago, Dr. Larson said, she joined a door-to-door vaccination drive in northern Nigeria as a Unicef communications officer, “and even then we were trying to calm rumors that the C.I.A. was involved,” she said. The Iraq and Afghanistan wars had convinced poor Muslims in many countries that Americans hated them, and some believed the American-made vaccine was a plot by Western drug companies and intelligence agencies.

Since the vaccine ruse in Pakistan, she said, “Frankly, now, I can’t go to them and say, ‘The C.I.A. isn’t involved.’ ”

Dr. Pate said the attack would not stop the newly reinvigorated eradication drive, adding, “This isn’t going to deter us from getting everyone vaccinated to save the lives of our children.”

Aminu Abubakar contributed reported from Kano, Nigeria.

Career Couch: Moving On From a Job That Has Defined You

Q. You want to move into management or a higher executive position, but you’re so good at your current job that you’re now defined by it. How can you find a way out of this pigeonhole?

A. Start with some self-reflection, says Michael L. Buckman, managing director of executive advisory services at the BPI Group, a management consulting firm in Chicago. You can’t just walk into your boss’s office and say, “I want a different job,” so list for yourself your passions, skills and abilities and how those could translate to another position in the organization, he says. “Is there another role you really aspire to?” he asks. “And how will you, in that role, add value to the company?”

Once you determine where in the company you see yourself moving, create a plan to get there. Start by talking to your manager. Express your gratitude for all you’ve learned and accomplished and emphasize how much you value being a part of the organization, says Susan Battley, chief executive of Battley Performance Consulting in East Setauket, N.Y.

Be sure to come to the conversation with ideas about how to begin your transition. “Don’t just say you feel your career needs to grow, because then you’ve put all this on your boss,” Ms. Battley says. “Instead, say things like, ‘I’m looking for opportunities to manage a team or have more exposure to customers.’ ”

Q. What if your boss is only reluctantly on board?

A. Your manager may have anxieties tied to a change like this, so be reassuring. Make it clear that you understand how heavily your boss relies on you and that you will help to find and develop a good replacement. Stress that “you are committed to the department meeting its goals and that you would never go off and leave him in the lurch,” says Allan R. Cohen, a management professor at the San Francisco campus of Babson College.

Don’t just talk about how this transition will benefit you; think about how it will benefit your boss, too. For instance, Professor Cohen says, note that the department “will look good for developing people who have an interest in wider aspects of the business. ”

You should also meet with senior people at the company who can influence your boss, says John Beeson, principal at Beeson Consulting, a management consulting firm in Manhattan. “Let them know you feel frustrated and want a new role that allows you to spread your wings, but are also committed to the company,” he says.

Q. In order to move into a different position at the company, you need to find opportunities to learn and demonstrate other skills. How do you do that?

A. If you’ve worked for the same person for years and are seen as the right-hand man or woman, you are probably known for executing strategy but not necessarily for developing it. Your boss can help find projects where you can take on a leadership role, Mr. Beeson says, and can schedule a briefing on those projects with senior managers to raise your visibility. Showcasing your skills and talents to a broader set of managers will keep you at the top of everyone’s mind as positions within the company become available.

Ms. Battley suggests volunteering for a task force or a committee that deals with issues removed from what you’re currently handling. In small companies, you can sometimes preview a possible new job by taking on a few tasks and getting a feel for it, she says.

Q. Who else, inside or outside the company, can help you make this transition?

A. Anyone who is influential in your organization or industry could help you achieve your goals, so meet with as many of those people as you can. “Tell them you are looking for some career guidance and ask for their input about the kinds of jobs and experiences you need to have,” says Mr. Buckman of the BPI Group. They may not know you have an interest in a particular area or that you have certain valuable skills.

Try to include among your allies at least one person from human resources, Ms. Battley advises. The people in H.R. “know where vacancies are or can advocate for you if they know you’re interested in gaining other skills,” she says.

It’s possible that you will receive feedback you didn’t expect. “You could be told, ‘That’s a great idea, but it’s not something that would fit here’ or that the company doesn’t really need what you’re offering,” Mr. Buckman says. That may signal that it is time to look for opportunities outside your organization.

Big Bear locked down amid manhunt

The bustling winter resort of Big Bear took on the appearance of a ghost town Thursday as surveillance aircraft buzzed overhead and police in tactical gear and carrying rifles patrolled mountain roads in convoys of SUVs, while others stood guard along major intersections.

Even before authorities had confirmed that the torched pickup truck discovered on a quiet forest road belonged to suspected gunman Christopher Dorner, 33, officials had ordered an emergency lockdown of local businesses, homes and the town's popular ski resorts. Parents were told to pick up their children from school, as rolling yellow buses might pose a target to an unpredictable fugitive on the run.

By nightfall, many residents had barricaded their doors as they prepared for a long, anxious evening.

PHOTOS: A tense manhunt amid tragic deaths

"We're all just stressed," said Andrea Burtons as she stocked up on provisions at a convenience store. "I have to go pick up my brother and get him home where we're safe."

Police ordered the lockdown about 9:30 a.m. as authorities throughout Southern California launched an immense manhunt for the former lawman, who is accused of killing three people as part of a long-standing grudge against the LAPD. Dorner is believed to have penned a long, angry manifesto on Facebook saying that he was unfairly fired from the force and was now seeking vengeance.

Forest lands surrounding Big Bear Lake are cross-hatched with fire roads and trails leading in all directions, and the snow-capped mountains can provide both cover and extreme challenges to a fugitive on foot. It was unclear whether Dorner was prepared for such rugged terrain.

Footprints were found leading from Dorner's burned pickup truck into the snow off Forest Road 2N10 and Club View Drive in Big Bear Lake.

San Bernardino County Sheriff John McMahon said that although authorities had deployed 125 officers for tracking and door-to-door searches, officers had to be mindful that the suspect may have set a trap.

"Certainly. There's always that concern and we're extremely careful and we're worried about this individual," McMahon said. "We're taking every precaution we can."

PHOTOS: A fugitive's life on Facebook

Big Bear has roughly 400 homes, but authorities guessed that only 40% are occupied year-round.

The search will probably play out with the backdrop of a winter storm that is expected to hit the area after midnight.

Up to 6 inches of snow could blanket local mountains, the National Weather Service said.

FULL COVERAGE: Sweeping manhunt for rampaging ex-cop

Gusts up to 50 mph could hit the region, said National Weather Service meteorologist Mark Moede, creating a wind-chill factor of 15 to 20 degrees.

Extra patrols were brought in to check vehicles coming and going from Big Bear, McMahon said, but no vehicles had been reported stolen.

"He could be anywhere at this point," McMahon said. When asked if the burned truck was a possible diversion, McMahon replied: "Anything's possible."

Dorner had no known connection to the area, authorities said.

Craig and Christine Winnegar, of Murrieta, found themselves caught up in the lockdown by accident. Craig brought his wife to Big Bear as a surprise to celebrate their 28th wedding anniversary. Their prearranged dinner was canceled when restaurant owners closed their doors out of fear.

Check Out This Tiny, 3-D Printed Spaceship

The tiny spaceship in the video above was built using a microscale 3-D printer. At 125 micrometers long, the craft is about the length of a dust mite, and it took less than 50 seconds to produce. The super-fast, high-resolution printer that made the spaceship was introduced this week at the Photonics West fair by Nanoscribe GmbH, a company based in Germany that specializes in nanophotonics and 3-D laser lithography.

The printer crafted the spaceship using two-photon polymerization, in which ultra-short laser pulses activate photosensitive building materials. Afterward, the ship — based on a Hellcat fighter from the Wing Commander Saga — was inspected using an electron microscope. While the spacecraft can’t fly, thereby limiting its usefulness for space exploration (unlike, say, 3-D printed astrofood), the technology’s other tiny products include biological scaffolds, ultralight metamaterials, and channels that have found homes in biological research, photonics, and microfluidics.

Next step? We’d love to watch this thing launch into space, piloted by an army of microbes.

The New Old Age: The Executor's Assistant

I’m serving as executor for my father’s estate, a role few of us are prepared for until we’re playing it, so I was grateful when the mail brought “The American Bar Association Guide to Wills and Estates” — the fourth edition of a handbook the A.B.A. began publishing in 1995.

This is a legal universe, I’m learning, in which every step — even with a small, simple estate that owes no taxes and includes no real estate or trusts — turns out to be at least 30 percent more complicated than expected.

If my dad had been wealthy or owned a business, or if we faced a challenge to his will, I would have turned the whole matter over to an estate lawyer by now. But even then, it would be helpful to know what the lawyer was talking about. The A.B.A. guide would help.

Written with surprising clarity (hey, they’re lawyers), it maps out all kinds of questions and decisions to consider and explains the many ways to leave property to one’s heirs. Updated from the third edition in 2009, the guide not only talks taxes and trusts, but also offers counsel for same-sex couples and unconventional families.

If you want to permit your second husband to live in the family home until he dies, but then guarantee that the house reverts to the children of your first marriage, the guide tells you how a “life estate” works. It explains what is taxable and what isn’t, and discusses how to choose executors and trustees. It lists lots of resources and concludes with an estate-planning checklist.

In general, the A.B.A. intends its guide for the person trying to put his or her affairs in order, more than for family members trying to figure out how to proceed after someone has died. But many of us will play both these parts at some point (and if you are already an executor, or have been, please tell us how that has gone, and mention your state). We’ll need this information.

Editor’s Note: More information about “The American Bar Association Guide to Wills and Estates” can be found here.

Venezuela Announces Currency Devaluation

CARACAS, Venezuela (AP) — Venezuela's government announced Friday that is devaluing the country's currency, a change expected to push up prices in the heavily import-reliant economy.

Officials said the fixed exchange rate is changing from 4.30 bolivars to the dollar to 6.30 bolivars to the dollar.

The devaluation had been widely expected by analysts in recent months. It was the first devaluation to be announced by President Hugo Chavez's government since 2010.

Planning and Finance Minister Jorge Giordani said the new rate takes effect immediately, though the old rate would still be allowed for some transactions that already were approved by the state currency agency.

Venezuela's government has had strict currency exchange controls since 2003 and maintains a fixed, government-set exchange rate.

Under the currency controls, people and businesses must apply to a government currency agency to receive dollars at the official rate to import goods, pay for travel or cover other obligations.

While those controls have restricted the amounts of dollars available at the official rate, an illegal black market has also flourished and the value of the bolivar has recently been eroding. In black market trading, dollars have recently been selling for more than four times the official exchange rate of 4.30 bolivars to the dollar.

Fugitive ex-cop stayed in San Diego motel; military bases on alert

This post has been updated. See the note below for details.

Military bases in the San Diego area have been warned to be on the lookout for a fugitive former LAPD officer suspected of shooting three police officers early Thursday morning -- one of them fatally -- and killing an Irvine couple on Sunday.

Christoper Jordan Dorner, 33, is a former Navy reserve lieutenant with multiple weapons at his disposal, including an assault rifle, officials said. He is considered armed and extremely dangerous and alerts have been issued in California and Nevada.

Guards at military bases have been alerted that Dorner may have military identification and military-issue clothing. He has a military sticker on his vehicle windshield and was station in San Diego at times during his Navy career.

Dorner is believed to be connected to an attempted boat theft at the Southwestern Yacht Club in Point Loma, where he allegedly held an 81-year-old boat owner at gunpoint, tied him up and tried to steal the boat to flee to Mexico.

When that attempt was thwarted by mechanical difficulties, he apparently drove north to Corona.

Sometime after 1:30 a.m., Dorner is suspected of shooting an Los Angeles Police Department officer in Corona, then heading to Riverside where authorities say he "ambushed" two Riverside officers. Both officers were shot, one fatally. Police said he was seen wearing military fatigues.

Dorner is also wanted in connection with the slaying Sunday in Irvine of the daughter of a retired LAPD captain and her fiance.

Authorities confirmed Thursday morning that Dorner had stayed at a hotel on a local military base several days ago.

Dorner was able to check in at the motel on the San Diego Naval base but it was not clear how he gained access to the secured area, police told reporters.

"We have confirmation that he stayed here several days ago," Lt. Joseph Ramos said at a news conference.

He said Dorner had not been seen in the area on Thursday despite reports that he was still at the motel.

[Updated at 11:55 a.m.: Navy officials confirmed that Dorner checked into the base on Feb. 5, using military identification. He did not check out.]

Law enforcement authorities said they were concerned about Dorner's military background and weapons training.

Dorner received awards for his expertise with a rifle and pistol, according to military records obtained by The Times. He received an Iraq Campaign Medal and served in a mobile inshore undersea warfare unit.
