EVANDALE, Ohio (CNN) - John Dyer remembers being unable to sleep.
"I woke up at 4 in the morning and walked around the neighborhood. Part of my mind was just torn with anger. I wanted to go to Iraq and find those people who had done this and kill them," he said.
Two and a half years have passed since the knock on Dyer's door. The Marine flag still flies outside his suburban Cincinnati, Ohio, home, the Gold Star banner in the window a reminder of the message delivered by two Marines that August day.
