PULLMAN — Investigators were unable to determine what caused the fire that destroyed a storage building and its contents earlier this year on the outskirts of Pullman.

Darren Jones, fire marshal for the city of Pullman Fire Department, finished his investigation into the Feb. 8 blaze. While he was unable to pinpoint what started the fire, he said it was most likely an accident.

The blaze at Express Storage located on the Moscow-Pullman Highway was a costly one. Jones said there was at least $2 million in damages. The fire consumed several units containing motorhomes, vehicles, ATVs, boats, household items, appliances and personal effects.
