Richard Allen Rhyne, 23, of Angleton, Texas, was last seen on March 22, 1977. He left home that morning intending to go to his workplace in Freeport to check on his job and drove a distinctive 1969 Chevrolet 210 pickup with a white top, green body and a gold passenger door and fender, Texas plates HR3152. Neither Rhyne nor the truck was seen again.

Rhyne had epilepsy and needed medication, and his body bore a scar on the forehead plus healed fractures to his left arm and right hand. Authorities have said they believe foul play may have been involved, but no definitive answers have emerged and the case remains open. Anyone with information is asked to contact the Brazoria County Sheriff’s Office.
