An autopsy will be conducted Wednesday on a man Billings police believe died of a self-inflicted gunshot wound after shooting his brother on Saturday.

About 8:30 a.m. Saturday, Billings police responded to a possible shooting in the basement of 1132 N. 26th St. Officers located a dead man inside.

A second man was located at St. Vincent Healthcare where he had walked. He was treated for a minor gunshot wound and was released. After interviewing him, detectives learned he is the brother of the deceased.

The deceased male appears to have shot at his brother causing a minor injury, then turned the gun on himself, according to Police Lt. Casey Hafnter.

The autopsy will be conducted in Missoula.

No arrests have been made and the investigation is ongoing.
