The death of a person discovered with a gunshot wound to the head shortly after 10 a.m. Sunday in the 100 block of Gall Road in Columbia is under investigation.

An Illinois State Police crime scene services unit responded to the scene along with an official from the Monroe County coroner’s office.

Columbia police said having ISP assist at the scene is standard protocol, but no foul play is suspected in this case. A 40-year-old white male was found with what appeared to be a self-inflicted gunshot wound inside a maroon 2011 Nissan Maxima in the driveway of his property.
