Does Anyone Know the Name of this Movie?

It was something to do with a few guys of college age. One of them ends up accidentally shooting a girl he's making out with in a car on the beach while the others are near by. They all agree to bury her but 10/15 years later a building site is about to go up in that spot. So they have to go and dig up the body. They find out it was all a prank (staged death) and that one of the guys was in on it with her, and that very guy ends up getting killed for real by one of them as they are out looking for the body.
