LE MARS, Iowa (AP) — Police are investigating after the body of a Le Mars man was found in his home. Investigators say the death appears to be suspicious. The Sioux City Journal reports that the body of the 57-year-old John Peter Koley was found Wednesday afternoon on his kitchen floor. Officials believe Koley had been dead for several days before his body was found by his son.

Police were unable to immediately determine the manner of death. The body has been sent to the State Medical Examiner’s Office in Ankeny, for an autopsy Friday morning.
