Police arrested 22-year-old Cameron Lenzini after the August 21 explosion at a house on the 1000 block of Russell Avenue in Santa Rosa, accusing him of illegally manufacturing butane hash oil.[1] Cameron Lenzini was charged with manufacturing a controlled substance, setting fire to an inhabited building and two counts of child cruelty, and he entered a not guilty plea before Judge Christopher Honigsberg.[2] Judge Honigsberg granted Cameron Lenzini pretrial release, with terms meaning he likely would wear an electronic monitor and check in with pretrial services, and set his next court appearance for September 27.[2] The two additional suspects were Trisha Lenzini, the mother of Cameron Lenzini, and her boyfriend Efrain Gomez.[2] Trisha Lenzini, 43, and Gomez, 41, are convicted felons, and investigators believed the guns found in the home belonged to them.[2] Trisha Lenzini and Gomez turned themselves in on August 24 and were jailed on suspicion of committing four felony offenses.[2] Those suspected offenses were possession of stolen property, unlawful possession of a weapon, possession of a firearm by a felon and possession of ammunition by a felon.[2]

Police said they searched the home and found 12 guns, including three assault rifles, one of which was stolen.[2] Police also said they found cases of empty butane canisters, marijuana and more than $57,000 in cash.[2] During the search of the home, officers found 12 firearms including three assault rifles, among them a stolen AK-47 style rifle, along with cases of empty butane canisters, marijuana and more than $57,000 in cash.[1]

The August 21 blast blew the Russell Avenue home’s garage off its foundation, rendered the house uninhabitable and endangered Trisha Lenzini’s two young daughters who were inside.[2] Four adults and two children were evacuated, Santa Rosa firefighters put out the fire caused by the blast, and no major injuries were reported.[2] Hash oil, also known as honey oil, has a high concentration of THC, making it much more potent than regular marijuana.[2] Butane is sometimes used to extract the concentrated oil from marijuana leaves, a process that can fill a room with flammable, highly explosive gas.[2]
