On September 28, 2019 a semi-truck was traveling eastbound on the 91 Freeway when the trailer detached from the semi-truck and both the truck and trailer came to a stop in the lane of traffic. Arthur was on his way home from a shift as a police officer when he struck the rear of the disabled trailer, causing his vehicle to spin to the right and strike a second semi. Arthur died at the hospital, of injuries sustained in the crash.
