Boise, Idaho (CNN) -- Five American soldiers have been charged with killing Afghan civilians for sport and staging the slayings to look like legitimate war casualties. The youngest of those five -- a now 20-year-old private from Idaho -- came home a changed man, his mother says.
And, said Dana Holmes, the Army not only should have known something had gone dreadfully wrong, but commanding officers should be held responsible.
"The man that came home was not my son," said Holmes. "He was very thin. He'd lost about 50 pounds. He said the Army told him he had a parasite. I made him his favorite sandwich, and it took him two days to eat the whole sandwich. Just couldn't eat; he didn't sleep."
Pfc. Andrew Holmes was a healthy, 185-pound 18-year-old when he joined the Army, his mother said. He came home on leave in April -- weeks before the Army launched an investigation into the suspected illegal drug use by his platoon, Bravo Company, 2nd Battalion, 1st Infantry Regiment, Fifth Brigade.
