Police released video showing the truck, which has a blue cab and white trailer.

“We believe the truck’s make is Freightliner, and may be from a model year from 1998-2001,” police said. “The truck may have minor damage to its passenger side, and may have white paint transfer from the cruiser on it (the cruiser was a white unmarked vehicle).”
