The Marion County Sheriff’s Office and the Iowa State Patrol are asking for the public’s assistance. Marion County Sheriff Jason Sandholdt tells KNIA/KRLS that an abandoned vehicle was found, still running, north of Melcher Dallas this morning. There are reports of a man walking, perhaps with his shirt off, north towards Pleasantville and Des Moines. Authorities believe this man may have been the driver of the abandoned vehicle. The Iowa State Patrol is assisting in the search with an airplane, and the Knoxville Fire Department and possibly other agencies are also assisting. If anyone noticed a man walking, towards Pleasantville, Hartford, Knoxville, or Indianola, or picked up a man, please contact the Marion County Sheriff’s Office at 641-828-2220.
