KALKASKA COUNTY, MI -- Police are investigating an alleged home-invasion in which the homeowner shot an intruder following a struggle over a rifle in Kalkaska County.

A 26-year-old Kalkaska man is recovering Monday, April 15, at Munson Medical Center after undergoing surgery for a gunshot wound to the chest.

Police arrested the homeowner -- a 23-year-old Rapid City man. He was questioned and later released. The case will be forwarded to the Kalkaska County Prosecutor’s Office for review upon completion by the Kalkaska County Sheriff’s Office.

The incident began around 9 p.m. Saturday, April 13, when a 26-year-old Kalkaska man went to the residence of his ex-girlfriend’s current boyfriend, where she lives with him.

Police said the homeowner told the ex-boyfriend to leave. He complied, but then allegedly sent threatening messages to his ex-girlfriend and her current boyfriend.

“The messages declared that he was going to return to the residence to fight the current boyfriend,” police said in a report.

The Kalkaska man returned around 3:30 a.m. Sunday, April 14. He was met by the rifle-wielding homeowner, who demanded he leave the residence.

Police said the Kalkaska man forced his way into the residence and a struggle ensued over the rifle. The intruder gained control of the rifle “for a short time” and then a second struggle for the rifle began.

At one point, the homeowner produced a small caliber pistol and shot the Kalkaska man once in the chest. He was transported to Munson Medical Center for treatment.

The Kalkaska County Sheriff’s Office was assisted on scene by the Michigan Police Crime Lab and detectives, Clearwater Township Fire Department and Kalkaska EMS.
