Young couple goes on van tour of US, boy comes back with van - no girl

when someone snaps are they not capable of killing someone in any manner...crime of passion....he was absolutely guilty of what he did...i do not excuse a thing about that. All i am saying is i think he snapped and did the unthinkable. how many of us have been pushed to far and we started to do the unthinkable. Something we would never do when we are calm and about our wits. well most of the time we stop ourselves in time but you see it all the time in the news those that didnt catch themselves in time.
