HIGHLAND, Calif. — For two decades after her son's bomber went down in the Pacific Ocean during World War II, Vella Stinson faithfully wrote the U.S. government twice a month to ask if his body had been found — or if anyone was looking.

The mother of six strapping boys went to her grave without the answer that finally reached her two surviving sons 65 years later: the remains of Sgt. Robert Stinson are coming home.

Military divers recovered several pieces of leg bone from the wreckage of a B-24J Liberator bomber found at the bottom of the ocean off the coast of the island nation of Palau. DNA testing showed the femur fragments belonged to the 24-year-old flight engineer who died in combat on Sept. 1, 1944.

Stinson's remains arrived under U.S. Air Force escort Wednesday and received a burial Friday at Riverside National Cemetery with full military honors.

"He's not someplace on a little island or at the bottom of the ocean. He's home," said Edward Stinson, who was 9 when his brother died.

For Robert Stinson, the journey home was far from a sure thing.

Stinson's family knew only that his bomber had gone down in the Pacific Ocean after being hit by anti-aircraft fire. The government politely responded to his mother's letters but said again and again that no new information had surfaced.

The family learned that Stinson, who joined the Army Air Forces right out of high school, won several medals in the summer of 1944 for participating in dangerous attacks on Japanese airdomes, military installations and enemy ships. His plane was dubbed "Babes in Arms."

In 1994, a nonprofit group of adventurers and scuba divers began to search for the missing bomber off the waters of Koror, Palau's biggest island. The 15-member group, called BentProp, travels to the island nation each year for a month to search for some 200 missing U.S. World War II aircraft.

Half of the wrecks scattered in the waters around the archipelago's 300 tiny islands have missing crew members associated with them, said Daniel O'Brien, a member of the BentProp team. Stinson's plane had 11 crew members, and there were eyewitness reports of where it went down. Eight crew members went down with the plane; three parachuted out, but were captured by Japanese soldiers and are believed to have been executed.

The group attended reunions of Stinson's bomber squadron and the aging veterans told them where they thought they had seen the plane go down as the rest of the formation raced back to base at 200 mph. BentProp members methodically searched that area for six years, but found nothing.

Then, in 2000, several members of the group doing more research stumbled upon obscure black-and-white aerial photos in the National Archives that were taken by a crew member aboard another bomber just moments after Stinson's plane went down. The team thought it odd the photographer had taken shots when no bombs were falling, and then realized the pictures were probably an attempt to document where the bomber crashed.

The pictures indicated a splash zone eight miles from where BentProp had been looking.

The team dove the site in 2004 and instantly hit a jackpot: a B-24 propeller at 30 feet and then the plane, broken in three parts around a coral head where it had sat for more than 60 years. Debris was scattered at up to 70 feet deep.

The divers turned over their findings to the Joint Prisoners of War, Missing in Action Accounting Command, or JPAC, the government agency on O'ahu that searches for U.S. prisoners of war and missing soldiers.

Military divers soon confirmed the plane's identity and recovered hundreds of items from the ocean floor, including dozens of tiny bone fragments and personal effects.

In 2006, Edward Stinson and Richard Stinson, the other surviving brother, gave DNA samples. On Feb. 1, Richard Stinson got the call: their brother, the 6-foot-4 clown with curly hair and a love of sports and poker, was finally coming home.

Four other missing crew members were also identified through DNA and are being returned to their families. Other remains found at the site were identified as human but were too fragmented to be linked to the three other men aboard, said Air Force Lt. Col. Wayne Perry. They will, however, be memorialized with the entire crew at Arlington National Cemetery next spring.

"There's finally an ending to it," said Richard Stinson, now 87.

With Stinson's remains back home, his brothers are overwhelmed with mem-ories they stored away for decades — memories that, until now, are all they had.

"He has risen," said Edward Stinson. "Welcome home, brother."
