Rodney John Olsen, 32, vanished from his farm northeast of Mason City, Iowa, after leaving home about 1 a.m. on October 18, 1986. He had been living on an 800-acre grain farm with his girlfriend after moving from Britt, Iowa, and kept contact with his ex-wife and son in Britt. He told others he’d be back in an hour and was never seen again.

Several months later Olsen’s black 1978 Pontiac Sunbird was found abandoned in a trailer park in Forest City, Iowa. Investigators reported no clear signs of foul play or evidence at that scene. The case was later classified as endangered because of the unexplained circumstances, but extensive investigations produced no significant leads and it remains unsolved.

Does anyone have information about Olsen, his Pontiac, or sightings in the Forest City area in late 1986?
