Possible Hash Oil Fire Under Investigation

WESTMINSTER (CBS4) – Investigators in Westminster believe a house fire started as a result of hash oil extraction, but cannot get into the structure to make the exact determination because the chemical levels are too high.
The fire in the 4800 block of West 73rd Avenue began at about 8:15 p.m.
Westminster Firefighters responded to the 911 call placed by residents of the home. When they arrived, they found light smoke in the house and fire in the garage.
