Corey Haim’s mother said the actor had a fever the morning before he died of an apparent drug overdose, his mother told a Los Angeles 911 operator.

Authorities released the 911 tape related to the death last week of the 1980s teen star.

“He’s not breathing,” Judy Haim told the operator. “He’s 38 years old. I don’t know what’s going on. He had a fever this morning.”

During the 10-minute call, Judy Haim answered a series of medical questions before Los Angeles Fire Department paramedics arrived.

The coroner’s office has not listed a cause of death, but the Los Angeles Police Department has said the death appears to be some type of overdose.

State Attorney General Jerry Brown announced Wednesday that his office is investigating the possible connection between an illegal Southern California prescription drug ring and Haim’s death. The actor, whose credits included “The Lost Boys” and “Lucas,” died at a Burbank hospital after being found unresponsive in his apartment.

Brown said an unauthorized prescription under Haim’s name was found during an ongoing investigation of fraudulent prescription drug pads ordered from a San Diego vendor.
