Abstract: At 4:41 p.m. on Monday, January 10, 2022, an employee was driving a Freightliner truck and was dropping off a trailer at a trailer yard. The employee backed up the trailer into a vacant parking spot and parked. The employee did not set the parking brakes for the truck when he exited his cab to disconnect and uncouple the trailer. The employee pulled out on the 5th wheel lock control handle to release and uncouple the truck from the trailer. As the employee pulled the handle, the truck began rolling forward. The employee quickly reacted to truck rolling forward by running to the front of the it and leaned up against it in an attempt to stop it. Located directly behind the employee was another stationary trailer. As the truck continued rolling forward, the employee and truck began moving closer and closer to the stationary trailer until it crushed him against it. The employee suffered crushing injuries to his body resulting in death.
