BILLINGS — Police said Tuesday a man who was fatally shot at a Billings Heights residence was killed while assaulting a woman.
The fatal shooting happened shortly after 4 a.m. Monday at a residence in the 300 block of Nash Lane. Officers found 43-year-old Robert Aven Kolter from Roundup who had been shot. He died after being taken to the hospital.
In a press release Tuesday, police said investigators determined that Kolter had traveled from Roundup to see a 33-year-old woman who was staying at the Heights property. The two were in a relationship, police said.
A 34-year-old Billings man was living in a separate building on the property, police said.
Prior to the shooting, Kolter was assaulting the woman, police said. The woman was strangled and pistol-whipped and Kolter tried to force her to leave with him.
When Kolter put a gun to the woman's head, the 34-year-old man who lived there shot him, police said. The names of the woman and the 34-year-old man have not been released.
The investigation is ongoing, police said, and no arrests have been made.
