The forensic scientist examined pieces of broken plastic from the scene of an accident and parts from a 2003 Chevy Silverado truck. Through physical matching comparisons, the scientist found that pieces of gray and black plastic from the scene matched fractures in the truck's grill and headlamp bracket. This suggests the pieces of plastic came from damage to the truck during the accident.
