On June 13, 2021, officers of the Bozeman Police Department were asked to check the welfare of a male whom the caller had recently been unable to contact. Officers went to an address in the 100 block of N 9th Street in Bozeman to check on the welfare of the 79-year-old male. After not receiving a response, they entered the residence and ultimately found a male, later identified Steven Jay Kilwein, deceased on the floor.

The initial investigation indicated the death may have been the result of a construction accident. However, the continued investigation and an autopsy, conducted on June 15, indicated the death was the result of a criminal act.

At this time, it appears the suspect was known to the victim and that this was not a random act. It does not appear there is a general public safety concern.

Although no arrests have been made at this time, detectives are actively investigating the incident and have developed a possible suspect. Anyone with additional information regarding this incident is encouraged to contact Detective Ben King at 406-582-2035, Crimestoppers at 406-586-1131 or email crimetips@bozeman.net. Information leading to an arrest in this case may be eligible for a Crime Stopper’s reward.
