A WORK VAN TOWING A HOMEMADE TRAILER caused a fatal accident in Kent County, Michigan, yesterday.  The trailer carrying scrap metal came apart from the hitch and then went airborne into the oncoming traffic lane where it flew over one car and crashed through the windshield of the following vehicle, killing the driver.

WOOD-TV Grand Rapids has the video:

Investigators are trying to determine why the hitch pin came out from the receiver tube and whether or not the van had the required safety chains attached.  The van operator could be facing vehicular homicide charges if negligence was a contributing factor.
