We performed a detailed investigation and analysis that determined the deflagration and ensuing fire were caused by Mr. Collins’ pipe igniting a pool of gas vapors near the floor of his shack. These vapors were from a leaking gas can in his chemical storage cabinet. The chemicals in this cabinet were used in the cleaning & repair of automobile engines. Even though these chemicals could also be used in the production of methamphetamine, and even though Mr. Johnson’s car contained equipment used in and residue from the production of methamphetamine, there was no evidence of production at the time of the deflagration and fire. The murder charges against Mr. Collins were dropped.
