Case Description

Summary based on the NamUs case record (MP10207) and 14 other sources
Rodney John Olsen, a 32-year-old farmer from Mason City, Iowa, went missing on October 18, 1986. Olsen lived on an 800-acre grain farm northeast of Mason City with his girlfriend, having recently moved there from Britt, Iowa. He maintained contact with his ex-wife and son, who continued to live in Britt, often traveling to visit them. On the night of his disappearance, Olsen left his home around 1 a.m., stating that he would be back in an hour. However, he was never seen again.

Several months after Olsen went missing, his black 1978 Pontiac Sunbird was discovered abandoned in a trailer park in Forest City, Iowa. There were no indications of foul play or evidence at the scene to suggest what might have happened to him. Despite thorough investigations and the passage of decades, no significant leads have emerged, and Olsen’s case remains unsolved. His family, including his father, Myrlen Olsen, continued to hold onto hope for answers for many years, keeping in touch with the Cerro Gordo County Sheriff's Office.

Olsen’s case is classified as endangered due to the mysterious circumstances of his disappearance, but despite extensive investigations, it remains a cold case, leaving many questions unanswered about his fate.
