I did not see a thread for Melvin, so I thought I would start one. He's a Vietnam Vet.

Around 4:30 a.m. early Sunday morning, November 17, 1974, a passing Farragut truck driver discovered a body lying along Iowa Highway 42 near the foot of a hill about three miles west of Riverton, Iowa. He notified authorities, who identified the body as that of 26-year-old Melvin Price.

Price’s driver’s license listed his residence as Phoenix, Arizona, though he most recently had been living in Lincoln, Nebraska.

Fremont County Attorney Robert Leonard initially told media Price died of head injuries but refused to elaborate. A witness reported that Price appeared to have been beaten with a crowbar.

Fremont County Sheriff Bob Jenkins investigated the case along with the Iowa Bureau of Criminal Investigation.
