The name of the late actor Corey Haim was found on a fraudulent prescription for a powerful painkiller that authorities said was obtained through a major drug ring.
California Attorney General Jerry Brown's office said Friday records of the prescription in the name of the former teen heartthrob were found during an investigation of the ring that illegally obtained prescription pads and used the stolen identities of doctors to fill them out.
Los Angeles County coroner's officials, however, said they have not yet determined what killed the 38-year-old Haim on Wednesday.
State law enforcement authorities said they were investigating the drug ring and how the name of Haim, who battled addiction for years, appeared on the prescription.
Authorities have not yet confirmed that Haim actually filled the prescription or if someone was using his name to acquire the prescription.
Assistant Chief Coroner Ed Winter said four prescription drug bottles bearing Haim's name were found in the apartment where he collapsed, but all those drugs had been provided by a doctor who had been treating the actor.
