Marine Sgt. Jeremy Kocher stands watch near the body of Lance Cpl. Evenor Herrera in Eagle, Colo., as children and adults from the area poured in to pay their respects. Like many of the Marines stationed at Buckley Air Force Base in Aurora, Kocher says the funeral detail is the most difficult mission he's ever done. "I actually start thinking about it the moment I wake up. It's such an important job that I just don't want to mess it up," he said. "I just want it to be perfect."
