Authorities in Tennessee say a 74-year-old man was arrested on suspicion of killing his wife and a male victim inside of a garage in Cumberland County earlier this week.

According to WKRN, the incident took place at a garage on Genesis Road in Crossville, which is used by the Cumberland County schools.

Police were called to the scene of the shooting on Friday. After arriving, they reportedly discovered the bodies of 58-year-old Joy Nostom and 54-year-old Mark Gunter.

The suspect was also located at the scene. He was injured from what police believe was a self-inflicted gunshot wound.

Warren Nostom was transported to an area hospital via air ambulance.

After he received treatment for his injuries, police transported him to the Cumberland County Jail, where he was booked into custody with bail set at $4 million.

According to the Tennessee Bureau of Investigation, the case remains open and no additional information was immediately available.

“I want to express my deepest sympathy to the families and loved ones of the victims involved in today’s shooting at the Cumberland County Bus Garage,” wrote Cumberland County Mayor Allen Foster in a public statement shortly after the discovery.

Authorities say Warren Nostrom is expected to face criminal charges including two counts of first-degree murder.
