Well this was certainly a big and tragic mess, but of course the "Italian Journalist" wasn't killed. So how can AP let a headline like this slip through?
Most likely, accidentally on purpose, that's how.
Is this possibly a wishful-thinking slip on their part? Perish the thought!
UPdate 3/14: A couple of days ago I noticed that AP had changed their headline appropriately. It's comforting to know that AP editors are so much on the ball.
