Graphic video has just been released of a deadly accident two years ago involving a barge slamming into a tour boat in Philadelphia.

The security camera video will be entered as evidence as part of a wrongful death lawsuit.

Two Hungarian students were killed when a barge pushed by a tug collided with their disabled duck boat on the Delaware River. The accident dumped more than three dozen people into the river.

The video shows the barge moving toward the drifting duck boat and then running over the smaller vessel.
