The Bellevue Fire Department has not been able to determine the cause of a fire that ripped through the AutoNation Ford dealership on 116th Avenue Northeast last month, and evidence collected by firefighters is now being analyzed by the dealership’s insurance company.

While the cause of the fire is unknown, Bellevue Fire Lt. Rich Burke said a point of origin was found in the service area of the Ford dealership and investigators do not believe arson was involved. There was a lot of debris and burned out vehicles — around 30 — that needed to be removed after the fire on April 25, in order to begin investigating the blaze.

Burke said AutoNation’s insurance company has better tools for handling a forensic investigation of the evidence collected by the fire department, which it will use in determining what the dealership will receive for its financial and structural losses.

“We don’t have the type of high-tech forensic capacity to be able to do that,” Burke said.

AutoNation Ford employs more than 70 people, and has committed to financially supporting them while managers work on the site to establish temporary operations for services and sales, according to a news release issued a few days after the fire. Such operations have not restarted at the site at this time.
