The cause of a fire that destroyed the JP Enterprises Indoor Auto Auction & Sales building, 3301 1st Ave. S., has been ruled undetermined.
The fire, which razed the property on March 21, left behind insufficient information to determine an exact fire cause, according to Fire Marshal Mike Spini.
Billings firefighters and police responded to the fire around 8 p.m. at First Avenue South and South 33rd Street, where three buildings went up in flames.
The fire began on the east side of the building, Spini said.
About 20 firefighters, four engines and a ladder truck fought the blaze.
Firefighters spent more than four hours putting out the fire.
A lot of combustible material was contained inside the property.
“Tires, oil, 15 vehicles, furniture, you name it,” Spini said.
Fire crews returned to the scene several times over the next two days to put out flare-ups in the debris.
The majority of the property was uninsured.
