The White County Sheriff's Office (WCSO) says the body of Efren Beltran, 51, was found lying along Safely Road in the Judsonia area on Saturday.
During the course of the investigation detectives found that Beltran had driven to the area and shot himself in the chest.
The WCSO says Austin Flynn, 22, and Michael Hollingshead, 43, found Beltran dead in his truck and then pulled his body out before stealing the truck. They are both charged with Theft of Property (Felony) and Abuse of a Corpse and are being held on $25,000 bond.
Detectives are also looking for Steven Earl Raymond, 38, and Levi Garette Flynn, 20, for questioning in the case.
If anyone knows where either of them are, they're urged to call the White County Sheriff's Office Criminal Investigation's Division at (501) 279-6279. They are believed to live in the Judsonia and Bald Knob areas.
