California Attorney General Jerry Brown’s office said 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. “Corey Haim’s death is yet another tragedy linked to the growing problem of prescription drug abuse,” Brown said in a written statement. Los Angeles County coroner’s officials, however, said they have not yet determined what killed the 38-year-old Haim on Wednesday.
