SAN BERNARDINO, Calif. (AP) — Authorities say an explosion that tore apart a Southern California shack, killing one person and critically injuring two others, was caused by a lab illegally making hash oil.
The blast shortly before 7:30 p.m. Wednesday in Muscoy destroyed a 500-square-foot home.
Authorities say the body of 61-year-old Adrian Curiel of Chino was found buried in wreckage in the basement.
A critically injured woman with a head injury was found partially buried by debris in the basement and a burned man, also critically injured, was found walking near the home.
The Riverside Press-Enterprise (http://bit.ly/1vuclis ) says investigators determined that the blast was caused by production of hash oil — also called honey oil — a concentrated form of marijuana that is made by dissolving pot leaves in butane and then cooking it.
