Soldier's suicide leaves unanswered questions.(the suicide of Jamie Dalton)

The suicide of SPC Jamie Dalton, an infantryman in B Company, 1st Battalion, 15th Infantry Regiment, in 2006 shocked everyone who knew him. Many of the warning signs weren't evident in Dalton's behavior or the things he said to friends.

"I couldn't believe that he had killed himself," said Ronie Dalton, his mother. "It was the last thing I would have ever thought about. I never worried about him ever taking his life."

Soldiers he served with said Dalton was a well-liked, competent Soldier, who was cool under fire and could be depended on.

"If you were in the worst place on earth, he was the guy you wanted beside you," said SSG Robert Buffer, one of Dalton's best friends. "As a Soldier, he knew what he was doing. He knew tactics and weapons, he could drive anything, and he was an expert marksman. There was nothing he couldn't do."

In high school, he was an accomplished student, a national merit scholar and a good athlete, earning a starting position on his high school football team. After high school, Dalton surprised his family by deciding to join the Army.

"He was such an individual we were surprised when he joined the military," his mother said. "He was such a strong-willed person.

"We found that he loved the Army, though. He loved the adventure."
