Jesse Jerome Leopold, 23, of Jewell, Iowa, went missing on October 13, 2016. He was last seen leaving his shift at W&G Marketing, a meat processing plant, saying he needed to pick up medication. He never returned to work and has not been seen since.

Three days later Jesse’s purple Ford F-150 was found unlocked with the keys in the ignition at Ledges State Park, about 35 miles from Jewell. His work boots were inside the truck and his work smock was draped over the steering wheel, which relatives said was unusual for him. No activity has been detected on his phone or bank accounts.

Jesse had a history of bipolar disorder, depression, and anxiety and required medication; there are also reports he may have been self-medicating with street drugs. Authorities have not ruled out foul play, but no significant leads have emerged and searches and investigations have not turned up Jesse.

Anyone who knew Jesse, saw his truck at Ledges State Park in mid-October 2016, or has information about his movements that day is asked to contact the Boone County Sheriff’s Office.
