Decades later, tracking down the remains of Vietnamese prisoners

Organization helps find and identify the graves of those who died in Vietnamese 're-education' camps. Allowing their families a proper burial is crucial closure that many thought would never come

The last time Daniel Dien Luong saw his father was through the fence of a former army barracks in southern Vietnam more than 30 years ago.

His father was being held prisoner by the Communist government, which had arrested thousands of former military personnel to be "re-educated" after the Vietnam War.

The 13-year-old rode his bike two hours to visit his father every Saturday afternoon at 1 p.m. They waved at each other from afar as armed guards stood watch.

One day, the family discovered the barracks empty. It was two months before they received a letter from Luong Van Hoa, about 1,000 miles north of their home in Saigon, now known as Ho Chi Minh City.

In 1977, the letters stopped. The family feared the worst. A death certificate came 10 months later.

Luong, like hundreds of family members of captured South Vietnamese soldiers, has struggled to find out where his father is buried.

Next month, Luong and his mother will travel to Yen Bai province in hopes of recovering his father's remains, 32 years after his death.

They are able to do so with the help of a former South Vietnamese army major who heads a nonprofit called the Returning Casualty that has located and identified unclaimed graves of those who died in the prison camps.

Luong, now 46 and living in Los Angeles, said that finding even a trace of his father would bring closure to his family. In the Vietnamese Buddhist tradition, without a proper burial the spirit is lost, forever wandering.

"For my dad, he never had the chance to come home," Luong said. "His spirit could not come with us. There was always this sense of uncertainty".

Woods surges, but Johnson takes control

(CNN) -- Tiger Woods stormed back into contention at the U.S. Open at Pebble Beach with a third round 66, leaving him in third place, five shots behind new leader, American Dustin Johnson.

Woods looked set to continue his lackluster form of the first two days, opening his third round with consecutive bogeys at the 2nd and 3rd holes.

But the three-time U.S. Open winner responded like the Woods of old and immediately repaired the damage with three straight birdies.

Better was to follow as a faultless back nine, which included five more birdies, saw Woods come home in 31 strokes.

He left his best until last with birdies at the 16th and 17th holes, before producing a stunning second shot at the 18th to set up a simple two-putt birdie.

With 260 yards to the flag and a cypress tree in his way, Woods carved a 3-wood around the branches to 15 feet from the flag to round off one of his best playing days since returning from a five month lay off in April.

Study: Millions in Bangladesh exposed to arsenic in drinking water

(CNN) -- It could be the worst mass poisoning in history. And the terrible irony is that it may all be due to an idealistic push to clean up drinking water for some of the world's poorest people.

A new study published in British medical journal The Lancet says that up to 77 million people in Bangladesh are being exposed to toxic levels of arsenic, potentially taking years or decades off their lives.

An international team of researchers from Chicago, New York and Bangladesh followed 12,000 people over the past decade, monitoring their arsenic intake and mortality rates from contaminated wells.

By the end of the study, one in five deaths were determined to be directly related to elevated arsenic levels in their system. Stretch that over the entire population that takes its water from wells, and the impact is daunting.

The problem has been known about for years, if not the overall deadly impact.

South African doctor invents female condoms with 'teeth' to fight rape

(CNN) -- South African Dr. Sonnet Ehlers was on call one night four decades ago when a devastated rape victim walked in. Her eyes were lifeless; she was like a breathing corpse.

"She looked at me and said, 'If only had teeth down there,'" recalled Ehlers, who was a 20-year-old medical researcher at the time. "I promised her I'd do something to help people like her one day".

Forty years later, Rape-aXe was born.

Ehlers is distributing the female condoms in the various South African cities where the World Cup soccer games are taking place.

The woman inserts the latex condom like a tampon. Jagged rows of teeth-like hooks line its inside and attach on a man's penis during penetration, Ehlers said.

Once it lodges, only a doctor can remove it -- a procedure Ehlers hopes will be done with authorities on standby to make an arrest.

Virginia hospital: Former NBA star Manute Bol dead at 47

(CNN) -- Manute Bol, one of the tallest players in NBA history, died Saturday at the age of 47, a spokeswoman with the University of Virginia Medical Center confirmed to CNN.

The hospital did not disclose the cause of death.

Bol, who was listed at 7-feet-7 inches tall and 225 pounds, played for the Washington Bullets, Golden State Warriors, Philadelphia 76ers and Miami Heat in his 10-year career.

The native of war-torn Sudan was known during and after his career for his charity work for his home country.

"He was a wonderful person. He would always talk about the civil war going on in Sudan, because he was sending all of his money back to Sudan," Charles Barkley, Bol's teammate on the 76ers and an NBA analyst for TNT, told CNN's Don Lemon. "I can honestly say I never played with a better person," Barkley said.

"He never forgot about the Sudan. He would talk to us about it all the time. ... The world is not a better place today; It's worse because we don't have Manute Bol," he added.

Twin suicide car bombings in central Baghdad kill 26

At least 26 people have been killed in a twin suicide car bombing close to a state-owned bank in the Iraqi capital, Baghdad, officials have said.

More than 50 others were also hurt when the vehicles exploded simultaneously outside the Trade Bank of Iraq's headquarters in the Yarmouk district.

The blasts severely damaged the building and the nearby offices of an interior ministry identity-card centre.

There has been increased unrest in Iraq since March's parliamentary election.

The poll produced no outright winner, and a deal between the various parties to form a coalition government has not yet been reached.

Iran executes militant group leader

(CNN) -- Iranian authorities have executed the leader of a Sunni militant group blamed for dozens of attacks in the country, state media said Sunday.

Abdolmalek Rigi, who headed Jundallah (Soldiers of God), was hanged after being convicted of committing 79 crimes, including armed robbery, planting bombs and attacks against police and military forces, Press TV reported.

Authorities arrested him February 23 when he was on a flight from the United Arab Emirates to Kyrgyzstan, Press TV said.

Iran has blamed Jundallah for carrying out deadly bombings, abductions and targeted killings in the southeastern Sistan-Balochistan province, which borders Pakistan. It has accused the group of trying to destabilize Iran with the backing of the West.

Jundallah claims it has no separatist aspirations but rather it wants the predominantly Shiite country to stop persecuting the Sunni Balochis who live in the province.

The province lies about 700 miles (1,100 kilometers) southeast of Tehran.

Mexican officials: Mayor of Guadalupe killed by gunmen

(CNN) -- Gunmen shot and killed the mayor of the Mexican town of Guadalupe as his wife and child watched, the mayor of nearby Ciudad Juarez told CNN.

Mexican federal police confirmed the shooting death of Guadalupe Mayor Jesus Manuel Lara Rodriguez.

Ciudad Juarez Mayor Jose Reyes Ferriz said Lara, who maintained what was apparently a second home in Juarez, was killed outside that house as he walked to his car.

"He was a very good man, a man set on bringing law and order to that city," said Reyes.

"This is a big loss," he said.

Lara, who became the mayor of Guadalupe in 2007, had apparently taken up residence in Juarez to protect his family, Reyes told CNN. He kept his official home in Guadalupe.

Colombians to vote in runoff presidential election

(CNN) -- Colombians will head to the polls Sunday to cast their votes in a runoff presidential election.

Former Defense Minister Juan Manuel Santos, who got 46.5 percent of the votes in the first round of elections in May, is leading in polls. A high-profile hostage rescue by Colombia's military gave another boost to his candidacy last week.

He is facing former Bogota Mayor Antanas Mockus, who received 21.5 percent of votes in the May election.

The winner of the runoff will replace Alvaro Uribe, a two-term president who has high approval ratings for his tough stand against Marxist guerrillas who have been waging war against the government since the 1960s.

Uribe almost pulled off a third run for president, before a court stepped in and put an end to his campaign.

Poles vote to replace president killed in crash

(CNN) -- Poles headed to the polls Sunday to elect a new head of state to replace President Lech Kaczynski, who was killed in a plane crash in April.

The election pits Kaczynski's twin brother, Jaroslaw Kaczynski, against Parliament Speaker Bronislaw Komorowski, who has been acting president since the crash.

The two are among 10 candidates in the election originally planned for the autumn but brought forward after Kaczynski died.

Jaroslaw Kaczynski, once prime minister, is a divisive figure in Polish politics. His far-right Law and Justice party runs on a nationalist platform with the slogan, "Poland comes first".

"Poland has to be a strong country, otherwise it will not exist," he said recently. "I want to tell everyone here that as president I won't just be the head of state -- I will look after the strength of the Polish nation".

Recent polls show him trailing Komorowski, who is in the lead. The Parliament speaker is a moderate running for the center-right Civic Platform.

If I die, who will teach my daughters?

Editor's note: Imagine being a father and finding out you were going to die. Who would be there for your kids? Hear from one man who thought only of his daughters when he was faced with the news. Watch "Dads for My Daughters," a special Dr. Sanjay Gupta documentary to air June 19 and 20 at 8 p.m. ET on CNN

NEW YORK (CNN) -- Bruce Feiler remembers how he felt in May 2008. "I was a healthy person," and he was on the top of the world. Happily married, father to twin girls and a best-selling author. His book "Walking the Bible" was celebrated, and it gave him the nickname, "The Walking Guy". He made a living exploring the world, literally walking in other people's shoes.

But on that day in May, he was stopped in his tracks by a routine blood test. "My doctor says your alk phosphatase number is high," Feiler recalls. "She explains that alk phosphatase vaguely suggesting that there is something wrong with your liver or your bones. Another test, my liver is cleared and she says almost like on a whim, why don't you get a full-body bone scan?"

That test revealed a growth on his left femur, or thighbone. Feiler remembers his doctor was not concerned. "She says. It looks like nothing, don't worry, it's not like you have cancer. I repeated that a lot. 'Don't worry,' I say to my parents. 'Don't worry,' I say to my wife. 'Don't worry,' I say to myself. I don't have cancer".

But Feiler's wife, Linda, had a hunch that something was wrong: "You know as a wife, as a spouse. You know as a parent when something's just off. And he just didn't look himself".

A follow-up X-ray and MRI of his left leg revealed an 8-inch cancerous tumor. The official diagnosis was an osteosarcoma. Osteosarcomas strike just 900 Americans a year. Two-thirds of them are younger than 40. Feiler was 43.
