(Le Mars) — Plymouth County authorities are investigating what they refer to as a “suspicious death.” At about 4:00 p.m. Wednesday afternoon, the Plymouth County Communications Office received a call about a person found dead in his
home at 34782 Highway 3 of Le Mars. Plymouth County Sheriff Mike Van Otterloo confirmed the deceased is 57 year old, John Koley. Van Otterloo says a family member found Koley dead in the kitchen area of his home.

Crime scene tape has been placed around the Koley residence. Van Otterloo says Koley’s body was taken to the State Medical Examiner’s office in Ankeny where an autopsy is scheduled for Friday morning.

The Plymouth County Sheriff says the condition of the home leads them to believe the death has suspicious circumstances.

The Woodbury County Sheriff’s Crime Scene Team is assisting Plymouth County with the investigation. Van Otterloo says the federal agency of Alcohol, Tobacco, and Firearms (A-T-F) has also been contacted.

Koley is a property owner with several buildings located in downtown Le Mars, as well as he owned various land parcels throughout Plymouth County.
