GRAYVILLE — Authorities are conducting an ongoing death investigation following the discovery of a deceased individual inside a vehicle at the Road Ranger Truck Stop in Grayville.

Officials confirmed that the deceased has been identified as Mark Willoughby of Evansville, Indiana. At this stage, investigators are working to determine the circumstances surrounding the death, and the case remains under active review pending final findings from the coroner’s office.

According to law enforcement, the vehicle was discovered parked at the location for an extended period of time before concern was raised by individuals at the truck stop.
