Criminal Probe Opened Into LA Explosion

LOS ANGELES (AP) – Police and fire investigators have launched a criminal probe into the cause of an explosion at a hash oil manufacturer in Los Angeles that injured a dozen firefighters. They are trying to determine what might have sparked the blast that shot a ball of flames out of the downtown building Saturday and sent crews running for their lives. Eight firefighters remained hospitalized Sunday: two were in critical condition, but all are expected to survive. A fire captain described the business where the explosion occurred as a maker of “butane honey oil.” Butane is an odorless gas that is used to extractáthe chemical THC from cannabis to create a highly potent oil.
