For three days straight, Marines stood watch over the body of 2nd Lt. James Cathey, taking periodic breaks in a room within the mortuary, where Staff Sgt. David Rubio rubbed his eyes after a nap. Rubio was sent to represent the Marines from the University of Colorado, where he first met Cathey. "I've never stood that kind of duty," Rubio said. "When you're in college, you're so detached from what's happening in Iraq ... The more we talk about it the harder it seems to get."
