A 42-year-old inmate who experienced medical complications and died in his cell in February died as a result of multiple drugs in his system, a coroner’s release said Monday.

Albert Jurgen’s death the morning of Feb. 13 was an accident, the release said.

He had heroin, methamphetamine and codeine in his system when he died in a single-person cell at Tehachapi’s California Correctional Institution.
