When Jeffrey Henthorn, 25, returned from his first tour of duty in Iraq, his family noticed that something was not right. He woke up with nightmares and laughed callously at photos he took of Iraqis who had been shot and dismembered. When he was called up for his second tour of duty, he sobbed to his mother that he didn't want to go back. Two months later Henthorn’s family received the grim news that he had shot and killed himself with an M-16 rifle at an Army camp in Balad, Iraq.

>>In a web video interview, Henthorn's parents talk about the signs they wish they had paid attention to, and the need for an institutional safety net for troubled soldiers.
