Shasta County authorities say a man burned in a Cottonwood explosion was allegedly making hash oil from marijuana. The explosion and fire damaged a First Street home Monday and left 22 year old Jeffrey Bolds with 2nd and 3rd degree burns to his face and hands. A teenage girl and 2 month old infant were also in the house at the time, but were not injured. The child was placed into protective custody. The Shasta Interagency Narcotics Task Force says Bolds was allegedly using a solvent to extract hash oil, when vapors ignited.
