A young shooting victim wrestles with his fears

After the nightmares started, Davien Graham avoided his bicycle.

In his dreams, he pedaled his silver BMX bike through his neighborhood, heard gunfire and died.

If I stay off my bike, I'll be safe, he thought.

He placed it in a backyard shed, where it sat for months. But Jan. 12, 2008, dawned so spectacular that Davien decided to risk it.

He ate Cap'n Crunch Berries cereal, grabbed the bike and rode a half-mile west to Calvary Grace, a Southern Baptist church that was his haven.

Davien lived with an unemployed aunt and uncle, a former Crip, and five other kids in a cramped four-bedroom house in Monrovia, about 20 miles east of Los Angeles.

Yet as a 16-year-old junior at Monrovia High School, Davien earned A's and B's, played JV football and volunteered with the video club. He cleaned the church on Saturdays for minimum wage.

If I live right, God will protect me.

That afternoon, sweaty from cleaning, Davien reached for his wallet to buy a snack — only to realize he had forgotten it at home.

After returning to his house, he caught his reflection in the front window. He was 6 feet 2 and wiry. His skinny chest was beginning to broaden. He was trying to add weight to his 160-pound frame in time for varsity football tryouts.

He showered, told his aunt he would be right back and again jumped on his bike, size-14 Nike Jordans churning, heading for a convenience store near the church.

At the store, he bought Arizona fruit punch and lime chili Lay's potato chips. He recognized a kindergarten-age Latino boy and bought him Twinkies.

Davien pedaled down the empty sidewalk along Peck Road. He could hear kids playing basketball nearby. As he neared the church, a car passed, going in the opposite direction. He barely noticed.

He heard car tires crunching on asphalt behind him. He glanced back, expecting a friend.

Instead he heard: "Hey, fool."

The gun was gray. It had a slide. Davien recognized that much from watching the Military Channel.

Behind the barrel, he saw forearms braced to fire and the face of a Latino man, a former classmate.

The gunman shouted, "Dirt Rock!," cursing a local black gang, the Duroc Crips.

Davien's mind raced: Don't panic. Watch the barrel. Duck.

Suddenly, he was falling. Then he was on the ground, looking up at the church steeple and the cross.

Israel's Rocket-Hunting Ace Got His Start Playing <em>Warcraft</em>

War has once again erupted between Hamas and the Israel Defense Forces, with the Gaza-based militant group launching hundreds of rockets and missiles at Israeli towns. But many of these projectiles never made it to their targets, thanks to the new Iron Dome missile defense system that’s arguably become this conflict’s most important technological difference-maker. This article, first published in April, tracks the story of Iron Dome’s most prolific “gunner.” While his record for shooting down missiles and rockets has by now undoubtedly fallen, the tale still gives insight into the battle now gripping Israel and Gaza.

KFAR GVIROL, Israel — While many of the boys in Idan Yahya’s high school class were buffing up and preparing themselves for selection into elite combat units, this gawky teenager was spending “a lot of time” playing Warcraft — the real-time strategy computer game where opposing players command virtual armies in a battle to dominate the fictional world of Azeroth.

Four years later, the high school jocks who sweated it out in pre-military academies so they could make the cut into the Israel Defense Force’s Special Operations units are now crawling through the sand dunes on the outskirts of the Gaza Strip and watching while Idan knocks rockets out of the sky hundreds of meters above their heads. Idan Yahya, 22, an Iron Dome “gunner” in the Active Air Defense Wing 167, currently holds the record for the number of rockets intercepted: eight.

People in the army describe him variously as a geek and an ace. But the geek who grew up playing Warcraft is now a highly prized soldier on the cutting edge of real war craft. He’s the Israeli army’s top rocket interceptor.

The Iron Dome is a mobile anti-rocket interception system that Israel moves around the country to shoot down the rockets fired at its civilian population centers by armed groups in Gaza and southern Lebanon. Its radar picks up launches and fires interceptor missiles at them if they’re calculated to be heading towards populated centers. The system has become increasingly important as Hamas, Hezbollah and other groups amass surface-to-surface missiles to hit the Israeli home front with, thus bypassing the Israel Defense Force’s overwhelming advantage of concentrated firepower and fighter aircraft. Should Israel attack Iran’s nuclear installations, the expected rocket reprisals from the armed groups on its borders will keep Iron Dome very, very busy.

As the war between Israelis and Arabs enters its sixth decade (or its 500th depending on who you ask), it is increasingly becoming a hi-tech rocket war. The IDF’s Director of Military Intelligence Maj. Gen. Aviv Kochavi in February said there were 200,000 rockets aimed at Israel from the south, north and east. And in this increasingly technological battlefield of rockets, anti-rocket interceptors, radars, control rooms, drones and drone hacking, it is soldiers like Idan Yahya (and whoever his counterparts on the Arab side are) who are making the most impact.

Computer geek, keyboard combatant, soldier, call him what you will, Idan and others like him man the controls of the latest rock star in advanced military technology. “There are a lot of flashing blips, signs, symbols, colors and pictures on the screen. You look at your tactical map; see where the threat is coming from. You have to make sure you’re locked onto the right target. There’s a lot of information and there is very little time. It definitely reminds me of Warcraft and other online strategy games,” Idan says.

NY Times article questions what CEO knew of BBC sex scandal: can Mark Thompson survive?

LOS ANGELES (TheWrap.com) – The New York Times has turned its guns on one of its own, and right about now Mark Thompson must be looking for somewhere in the corporate suite to hide.

In a devastating article, the paper of record raises questions about what its newly minted chief executive officer knew about a pedophilia scandal at the BBC and when he knew it. Thompson stepped down as BBC director-general in September and assumed his new perch at The Times on Monday.

Yet his cross-Atlantic transition has been turbulent. He has found himself dogged by the scandal engulfing the BBC after allegations emerged that he tried to prevent an exposé by one of the network’s investigative programs into claims that children’s TV host Jimmy Savile routinely coerced teenage girls into having sex. Savile, who died in 2011, was one of the BBC’s biggest stars.

Thompson has maintained that he learned of the claims against Savile after leaving the BBC, but a legal letter indicates that he was aware of the accusations before he stepped down from his post, according to the article in The Times. In the piece, reporter Matthew Purdy writes that lawyers representing Thompson threatened to sue The Sunday Times over an article it was writing that claimed he had squelched his network’s investigative report on Savile’s sexual behavior. The letter was sent 10 days before Thompson resigned from the BBC.

The Sunday Times is owned by Rupert Murdoch’s News Corp. and is based in the United Kingdom.

“There were other moments during Mr. Thompson’s final months at the BBC – involving brief conversations and articles appearing in London news media – when he might have picked up on the gravity of the Savile case,” Purdy writes. “But the letter is different because it shows Mr. Thompson was involved in an aggressive action to challenge an article about the case that was likely to reflect poorly on the BBC and on him.”

The letter purportedly included a summary of Savile’s alleged abuses. The Times reports that an aide to Thompson said he authorized the letter orally, but was not fully informed about its contents.

After the story broke, speculation mounted on Twitter among media watchers that Thompson’s position at The Times might be in jeopardy.

“The odds on Mark Thompson staying as CEO of the New York Times just changed,” Jay Rosen, a journalism professor at New York University, tweeted.

At the very least, it appears that reporters at the paper have taken to heart Public Editor Margaret Sullivan’s charge to cover the BBC scandal aggressively.

“As the BBC has found out in the most painful way, for The Times to pull its punches will not be a wise way to go,” Sullivan wrote.

As Thompson, still nursing Purdy’s uppercut, just found out, The Times looks ready to put some muscle into it.

The Neediest Cases: Emerging From a Bleak Life to Become Fabulous Phil

For years, Phillip Johnson was caught in what seemed like an endless trench of bad luck. He was fired from a job, experienced intensifying psychological problems, lost his apartment and spent time in homeless shelters. At one point, he was hospitalized after overdosing on an antipsychotic drug.

“I had a rough road,” he said.

Since his hospital stay two years ago, and despite setbacks, Mr. Johnson, 27, has been getting his life on track. At Brooklyn Community Services, where he goes for daily counseling and therapy, everybody knows him as Fabulous Phil.

“Phillip is a light, the way he evokes happiness in other people,” his former caseworker, Teresa O’Brien, said. “Phillip’s character led directly to his nickname.”

About six months ago, with Ms. O’Brien’s help, Mr. Johnson started an event: Fabulous Phil Friday Dance Party Fridays.

One recent afternoon at the agency, 30 clients and a few counselors were eating cake, drinking soft drinks and juice, and grooving for 45 minutes to Jay-Z and Drake pulsating from a boom box.

Mr. Johnson’s voice rose with excitement when he talked about the party. Clients and counselors, he said, “enjoy themselves.”

“They connect more; they communicate more,” he continued. “Everybody is celebrating and laughing.”

The leadership Mr. Johnson now displays seems to be a far cry from the excruciatingly introverted person he was.

As an only child living with his single mother in public housing in Bedford-Stuyvesant, Brooklyn, he said, he tended to isolate himself. “A lot of kids my age would say, ‘Come outside,’ but I would always stay in my room,” he said. He occupied himself by writing comic books or reading them, his favorites being Batman and Spiderman because, he said, “they were heroes who saved the day.”

After graduating from high school in 2003, he worked odd jobs until 2006, when he took a full-time position at a food court at La Guardia Airport, where he helped to clean up. The steady paycheck allowed him to leave his mother’s apartment and rent a room in Queens.

But the depression and bleak moods that had shadowed him throughout middle and high school asserted themselves.

“My thinking got confused,” he said. “Racing thoughts through my mind. Disorganized thoughts. I had a hard time focusing on one thing.”

In 2008, after two years on the job, Mr. Johnson was fired for loud and inappropriate behavior, and for being “unpredictable,” he said. The boss said he needed counseling. He moved back in with his mother, and in 2009 entered a program at an outpatient addiction treatment service, Bridge Back to Life. It was there, he said, that he received a diagnosis of schizophrenia and help with his depression and marijuana use.

But one evening in May 2010, he had a bout with insomnia.

He realized the antipsychotic medication he had been prescribed, Risperdal, made him feel tired, he said, so he took 12 of the pills, rather than his usual dosage of two pills twice a day. When 12 did not work, he took 6 more.

“The next morning when I woke up, it was hard for me to breathe,” he said.

He called an ambulance, which took to Woodhull Hospital. He was released after about a month.

Not long after, he returned to his mother’s apartment, but by February 2011, they both decided he should leave, and he relocated to a homeless shelter in East New York, where, he said, eight other people were crammed into his cubicle and there were “bedbugs, people lying in your bed, breaking into your locker to steal your stuff.”

In late spring 2011, he found a room for rent in Manhattan, but by Thanksgiving he was hospitalized again. Another stint in a shelter followed in April, when his building was sold.

Finally, in July, Mr. Johnson moved to supported housing on Staten Island, where he lives with a roommate. His monthly $900 Social Security disability check is sent to the residence, which deducts $600 for rent and gives him $175 in spending money; he has breakfast and lunch at the Brooklyn agency. To assist Mr. Johnson with unexpected expenses, a grant of $550 through The New York Times Neediest Cases Fund went to buy him a bed and pay a Medicare prescription plan fee for three months.

“I was so happy I have a bed to sleep on,” he said about the replacement for an air mattress. “When I have a long day, I have a bed to lay in, and I feel good about that.”

Mr. Johnson’s goals include getting his driver’s license — “I already have a learner’s permit,” he said, proudly — finishing his program at the agency, and then entering an apprenticeship program to become a plumber, carpenter or mechanic.

But seeing how his peers have benefited from Fabulous Phil Fridays has made him vow to remain involved with people dealing with mental illnesses or substance abuse.

He was asked at the party: Might he be like the comic-book heroes he loves? A smile spread across his face. He seemed to think so.

The iEconomy: As Boom Lures App Creators, Tough Part Is Making a Living

Daniel Rosenbaum for The New York Times

Shawn and Stephanie Grimes’s efforts have cost $200,000 in lost income and savings, but their apps have earned less than $5,000 this year.

ROSEDALE, Md. — Shawn and Stephanie Grimes spent much of the last two years pursuing their dream of doing research and development for Apple, the world’s most successful corporation.

But they did not actually have jobs at Apple. It was freelance work that came with nothing in the way of a regular income, health insurance or retirement plan. Instead, the Grimeses tried to prepare by willingly, even eagerly, throwing overboard just about everything they could.

They sold one of their cars, gave some possessions to relatives and sold others in a yard sale, rented out their six-bedroom house and stayed with family for a while. They even cashed in Mr. Grimes’s 401(k).

“We didn’t lose any sleep over it,” said Mr. Grimes, 32. “I’ll retire when I die.”

The couple’s chosen field is so new it did not even exist a few years ago: writing software applications for mobile devices like the iPhone or iPad. Even as unemployment remained stubbornly high and the economy struggled to emerge from the recession’s shadow, the ranks of computer software engineers, including app writers, increased nearly 8 percent in 2010 to more than a million, according to the latest available government data for that category. These software engineers now outnumber farmers and have almost caught up with lawyers.

Much as the Web set off the dot-com boom 15 years ago, apps have inspired a new class of entrepreneurs. These innovators have turned cellphones and tablets into tools for discovering, organizing and controlling the world, spawning a multibillion-dollar industry virtually overnight. The iPhone and iPad have about 700,000 apps, from Instagram to Angry Birds.

Yet with the American economy yielding few good opportunities in recent years, there is debate about how real, and lasting, the rise in app employment might be.

Despite the rumors of hordes of hip programmers starting million-dollar businesses from their kitchen tables, only a small minority of developers actually make a living by creating their own apps, according to surveys and experts. The Grimeses began their venture with high hopes, but their apps, most of them for toddlers, did not come quickly enough or sell fast enough.

And programming is not a skill that just anyone can learn. While people already employed in tech jobs have added app writing to their résumés, the profession offers few options to most unemployed, underemployed and discouraged workers.

One success story is Ethan Nicholas, who earned more than $1 million in 2009 after writing a game for the iPhone. But he says the app writing world has experienced tectonic shifts since then.

“Can someone drop everything and start writing apps? Sure,” said Mr. Nicholas, 34, who quit his job to write apps after iShoot, an artillery game, became a sensation. “Can they start writing good apps? Not often, no. I got lucky with iShoot, because back then a decent app could still be successful. But competition is fierce nowadays, and decent isn’t good enough.”

The boom in apps comes as economists are debating the changing nature of work, which technology is reshaping at an accelerating speed. The upheaval, in some ways echoing the mechanization of agriculture a century ago, began its latest turbulent phase with the migration of tech manufacturing to places like China. Now service and even white-collar jobs, like file clerks and data entry specialists or office support staff and mechanical drafters, are disappearing.

“Technology is always destroying jobs and always creating jobs, but in recent years the destruction has been happening faster than the creation,” said Erik Brynjolfsson, an economist and director of the M.I.T. Center for Digital Business.

Still, the digital transition is creating enormous wealth and opportunity. Four of the most valuable American companies — Apple, Google, Microsoft and I.B.M. — are rooted in technology. And it was Apple, more than any other company, that set off the app revolution with the iPhone and iPad. Since Apple unleashed the world’s freelance coders to build applications four years ago, it has paid them more than $6.5 billion in royalties.

Veteran L.A. County sheriff's deputy charged with murder

After spending much of his life putting people behind bars, a veteran L.A. County sheriff's deputy stood in handcuffs Thursday, charged with gunning down a former neighbor who apparently got into a fight with his son.

Francisco Gamez, 41, is accused of shooting Armando "Cookie" Casillas, a well-known figure in his blue-collar neighborhood in Sylmar.

Gamez was off duty, sitting in his car, when he allegedly fired two shots on the night of June 17, killing Casillas and narrowly missing a second man, prosecutors said.

Gamez, a 17-year veteran who worked as a detective in West Hollywood, was allegedly furious over a fight between his 20-year-old son and Casillas, 38, prosecutors said. The younger Gamez had called his father to the scene, authorities said.

Casillas was later found by relatives lying near his home, and died later at Providence Holy Cross Medical Center.

Gamez was removed from duty in July after witnesses and evidence tied the detective to the slaying, authorities said. He was arrested Wednesday and led handcuffed from his San Fernando home by his former co-workers.

On Thursday he was formally charged with murder, attempted murder and discharging a firearm from an occupied vehicle. Gamez could face 75 years to life in prison if convicted of all charges.

In court, where he stood handcuffed in a plexiglass cage, sheriff's deputies peeked into the room to gawk at their former colleague. Sheriff Lee Baca described the whole thing as "deeply disturbing."

Gamez is being held on $4-million bail.

On Beaver Street in Sylmar, where the shooting occurred, Casillas' photo sat in a frame in the midst of a makeshift memorial, along with a cross and a potted plant with U.S. and Mexican flags and candles.

"He was a sweetheart, and very generous," said Patsy Telles-Cabrera, who lived across the street from Casillas for years. "He would check in on my parents." She left a box of chocolates at the growing shrine.

"It never should have happened," said one neighbor. "This is a family neighborhood."

Russia's Stealth Fighter Could Match U.S. Jets, Analyst Says

Russia’s T-50 stealth fighter prototype, the first radar-evading warplane outside the U.S. when it debuted in January 2010, is slightly less stealthy than the American F-22 and about equal to the smaller F-35. But in several other respects the new warplane from the Russian Sukhoi design bureau is actually superior to the American models.

That’s the surprising conclusion of the first-ever public scientific analysis of the T-50′s Radar Cross-Section (RCS), completed this week by Dr. Carlo Kopp, an analyst with the independent think tank Air Power Australia.

“The shaping of the T-50 is inferior to that of the F-22 Raptor,” Kopp writes in his dense, jargon-heavy report. But the F-35 and T-50, he adds, exhibit “similar … RCS behavior.”

But Kopp’s assessment of the T-50 comes with caveats. Quite a few of them, actually. To match the stealthiness of the Lockheed Martin F-35 — to say nothing of the company’s F-22 — Sukhoi’s engineers will have to, among other changes, modify the T-50′s engines to a less obtrusive fitting and add a layer of radar-absorbing material to the plane’s skin.

With the revised engines and skin, the T-50′s “specular RCS performance will satisfy the Very Low Observable (VLO) requirement that strong specular returns are absent in the nose sector angular domain,” Kopp writes. Translated into plain English, Kopp’s saying that an optimized version of the Russian jet could be very, very difficult to detect by most radars as it’s bearing down on them.

Major refinements are standard practice as stealth prototypes go through development, it’s worth noting. The F-22 and the F-35 underwent big design changes as each was developed over 15 years or more. The T-50, only four of which have been built, has been flying for just under three years and isn’t scheduled to enter frontline service until 2016 at the earliest. There’s time for the Russians to finesse the design, just as the Chinese are doing with their stealth planes.

Granted, by 2016 the Americans could possess hundreds of combat-ready F-35s plus the roughly 180 F-22s already in service. The T-50 could make up for its lateness with impressive performance that in some ways exceeds even the F-22′s vaunted capabilities.

One Russian advantage is what Kopp calls “extreme plus agility” — a consequence of the T-50′s “advanced aerodynamic design, exceptional thrust/weight ratio performance and three dimensional thrust vectoring integrated with an advanced digital flight control system.”

The second advantage: “exceptional combat persistence, the result of an unusually large 25,000-pound internal fuel load,” Kopp writes. The T-50 could keep flying and fighting long after the F-22 and F-35 have run out of gas.

Moreover, the T-50 will dodge certain radars better than others, according to Kopp — and U.S. sensors are among the worst at detecting the T-50′s unique shape, he contends. Kopp’s breakdown of T-50 RCS by radar type shows Chinese “counter-VLO radars,” specifically designed to spot American stealth planes, detecting the T-50 best.

The next best sensors to use against the Russian fighter is the UHF radar aboard the U.S. Navy’s E-2 early-warning planes. American fighter radars, including those aboard the F-22 and F-35, are of middling effectiveness against the T-50, Kopp asserts.

“No fundamental obstacles exist in the shaping design of the T-50 prototype which might preclude its development into a genuine Very Low Observable design,” Kopp concludes.

In other words: Watch out, America! You’re now only one of three countries with a truly radar-evading warplane in the air.

NBC to replace “Today Show” producer, source says

(Reuters) – NBC is expected to name Alexandra Wallace, a senior vice president of the network’s news division, as the executive in charge of “The Today Show,” the latest reshuffling of the show’s personnel after it slipped to second in ratings this year behind “Good Morning America.”

Wallace, who would be the first woman in charge of the long-running NBC show that pioneered early morning TV in the United States, will be named along with a producer to replace Jim Bell, according to a person familiar with the decision.

Bell, who has headed the show since 2005, was blamed this year for the controversial firing of Ann Curry as anchor alongside Matt Lauer.

Curry was replaced by Savannah Guthrie in June.

“Good Morning America” or GMA, produced by Walt Disney‘s ABC unit, closed the gap with “Today.”

“Today,” the top-rated morning show for 16 consecutive years, started the current TV season number two. In late October, NBC drew 7,000 more viewers than GMA among 25 to 54 year-old viewers, the age group advertisers most want to reach, its first lead since September 10. GMA still led among overall viewers.

The first two hours of “The Today Show,” from 7 a.m. to 9 a.m., collected $ 485 million in ad revenues in 2011, up 6.6 percent from 2010, according to Kantar Media, which provides data to advertisers. GMA took in $ 299 million last year.

It is unclear when the changes at “The Today Show” will take effect, according to The New York Times, which first reported the shakeup.

Bell this summer produced NBC’s Summer Olympics coverage and is expected to become the full-time executive producer of the network’s ongoing Olympic coverage.

NBC, a unit of Comcast Corp., is also in the midst of layoffs at its entertainment unit, shedding 500 positions primarily at its cable channels. Jay Leno’s late night TV show cut about two dozen of its crew members about two months ago.

For Alzheimer’s, Detection Advances Outpace Treatment Options

Joshua Lott for The New York Times

Awilda Jimenez got a scan for Alzheimer’s after she started forgetting things. It was positive.

When Awilda Jimenez started forgetting things last year, her husband, Edwin, felt a shiver of dread. Her mother had developed Alzheimer’s in her 50s. Could his wife, 61, have it, too?

He learned there was a new brain scan to diagnose the disease and nervously agreed to get her one, secretly hoping it would lay his fears to rest. In June, his wife became what her doctor says is the first private patient in Arizona to have the test.

“The scan was floridly positive,” said her doctor, Adam S. Fleisher, director of brain imaging at the Banner Alzheimer’s Institute in Phoenix.

The Jimenezes have struggled ever since to deal with this devastating news. They are confronting a problem of the new era of Alzheimer’s research: The ability to detect the disease has leapt far ahead of treatments. There are none that can stop or even significantly slow the inexorable progression to dementia and death.

Families like the Jimenezes, with no good options, can only ask: Should they live their lives differently, get their affairs in order, join a clinical trial of an experimental drug?

“I was hoping the scan would be negative,” Mr. Jimenez said. “When I found out it was positive, my heart sank.”

The new brain scan technology, which went on the market in June, is spreading fast. There are already more than 300 hospitals and imaging centers, located in most major metropolitan areas, that are ready to perform the scans, according to Eli Lilly, which sells the tracer used to mark plaque for the scan.

The scans show plaques in the brain — barnaclelike clumps of protein, beta amyloid — that, together with dementia, are the defining feature of Alzheimer’s disease. Those who have dementia but do not have excessive plaques do not have Alzheimer’s. It is no longer necessary to wait until the person dies and has an autopsy to learn if the brain was studded with plaques.

Many insurers, including Medicare, will not yet pay for the new scans, which cost several thousand dollars. And getting one comes with serious risks. While federal law prevents insurers and employers from discriminating based on genetic tests, it does not apply to scans. People with brain plaques can be denied long-term care insurance.

The Food and Drug Administration, worried about interpretations of the scans, has required something new: Doctors must take a test showing they can read them accurately before they begin doing them. So far, 700 doctors have qualified, according to Eli Lilly. Other kinds of diagnostic scans have no such requirement.

In another unusual feature, the F.D.A. requires that radiologists not be told anything about the patient. They are generally trained to incorporate clinical information into their interpretation of other types of scans, said Dr. R. Dwaine Rieves, director of the drug agency’s Division of Medical Imaging Products.

But in this case, clinical information may lead radiologists to inadvertently shade their reports to coincide with what doctors suspect is the underlying disease. With Alzheimer’s, Dr. Rieves said, “clinical impressions have been misleading.”

“This is a big change in the world of image interpretation,” he said.

Like some other Alzheimer’s experts, Dr. Fleisher used the amyloid scan for several years as part of a research study that led to its F.D.A. approval. Subjects were not told what the scans showed. Now, with the scan on the market, the rules have changed.

Dr. Fleisher’s first patient was Mrs. Jimenez. Her husband, the family breadwinner, had lost his job as a computer consultant when the couple moved from New York to Arizona to take care of Mrs. Jimenez’s mother. Paying several thousand dollars for a scan was out of the question. But Dr. Fleisher found a radiologist, Dr. Mantej Singh Sra of Sun Radiology, who was so eager to get into the business that he agreed to do Mrs. Jimenez’s scan free. His plan was to be the first in Arizona to do a scan, and advertise it.

After Dr. Sra did the scan, the Jimenezes returned to Dr. Fleisher to learn the result.

Dr. Fleisher, sad to see so much plaque in Mrs. Jimenez’s brain, referred her to a psychiatrist to help with anxiety and suggested she enter clinical trials of experimental drugs.

But Mr. Jimenez did not like that idea. He worried about unexpected side effects.

“Tempting as it is, where do you draw the line?” he asks. “At what point do you take a risk with a loved one?”

At Mount Sinai Medical Center in New York, Dr. Samuel E. Gandy found that his patients — mostly affluent — were unfazed by the medical center’s $3,750 price for the scan. He has been ordering at least one a week for people with symptoms ambiguous enough to suggest the possibility of brain plaques.

Most of his patients want their names kept confidential, fearing an inability to get long-term care insurance, or just wanting privacy.

L.A. County sheriff's deputy held in fatal off-duty shooting

A veteran Los Angeles County sheriff's deputy was arrested Wednesday for allegedly shooting and killing a man in Sylmar while off-duty in June, authorities said.

The deputy, Francisco Gamez, 41, has been with the department for 17 years and was last working as a station detective in West Hollywood.

Law enforcement sources told The Times that the deputy's son got into a dispute with another person. The son, they said, called his father to the scene. The deputy allegedly drove up soon after and exchanged words before opening fire from inside his car, striking one man, the sources said.

He then allegedly drove a short distance before shooting at a second person, added the sources, who asked for anonymity because the investigation is ongoing.

That person was not injured, according to authorities.

The other victim, Armando Casillas, 38, was taken to a hospital, where he was pronounced dead from a gunshot wound to the chest just before midnight on June 17.

---

FOR THE RECORD:
An earlier version of this article misspelled the victim's first name as Armondo.

---

Neighbors said Gamez and Casillas lived a block apart.

In August, a person who identified himself as the victim's brother commented on the website of the Los Angeles Times, saying he suspected a deputy was responsible.

"We think he is a L.A. COUNTY SHERIFF," the comment stated. "The reason we think he is a Sheriff is that he shouted to my Brother "L.A. COUNTY SHERIFF WHERE YOU FROM" as if the sheriff was in a gang."

The person who wrote the comment could not be reached Wednesday evening.

At the time of the killing, authorities said the victim got into an argument with an unknown person. At some point, the other person left the area only to return and shoot Casillas in a drive-by, authorities said then. Now they are saying that the shooter was not the same person who initially got into the argument.

LAPD officers arrested Gamez on suspicion of murder, attempted murder and use of a firearm in the commission of a felony. He was booked into the LAPD's 77th Street station Wednesday in lieu of $4-million bail, officials said. He has not been charged.

Casillas' sister said that the family was thankful for the arrest, but that they were not prepared to discuss the events that led to the fatal shooting.

In a statement, Sheriff Lee Baca called the incident "deeply disturbing."

His spokesman Steve Whitmore said the department placed Gamez on leave July 3 after learning from the LAPD about the investigation.

"He's been stripped of all law enforcement power," Whitmore said. "It casts a pall over the scores and scores of deputy sheriffs that every day do their job."
