Rottle Field fire origin remains “undetermined”

MONTESANO — The cause of the fire that destroyed the Rottle Field grandstands at Montesano High School has been officially ruled “undetermined,” according to a press release issued Wednesday by the Montesano Fire and Police Departments.

The fire department recently received lab results from samples sent in for testing, but the results didn’t shed any light on the cause of the Sept. 16 fire. The departments are now asking for anyone who shot video or took pictures of the fire before firefighters arrived to send copies of those images to the fire department.

The investigation into the fire is ongoing.
