Corey Haim’s suspected overdose death earlier this week is now under investigation, and has been linked to an illegal, massive drug ring, according to reports.

Investigators say that an illegal drug prescription for Haim was found during an investigation of a ring responsible for thousands of illegal pharmaceutical sales.

The investigation linked more than 5,000 fraudulent prescriptions to the drug ring so far, officials said after combing a database of prescriptions in California.

investigators found one in Mr. Haim’s name for OxyContin. The ring is based in San Diego, where the county district attorney is currently prosecuting the case.

“This is a massive prescription drug ring,” Attorney General Jerry Brown said. “They get prescription drug pads, get illegal drugs, then sell them on the street.”

Corey Haim’s death shed new light on an illegal drug ring.

The assistant coroner for L.A. County said four prescription drug bottles bearing Mr. Haim’s name were found where he collapsed at his mother’s Burbank apartment.

Vicodin and Valium were among Haim’s drugs that were found.

The cause of the actor’s death has not been determined, adding that a toxicology report could take up to two months. There was no sign of foul play, officials say.

Police detectives have turned the investigation over to the coroner’s office after an autopsy Thursday showed Haim with an enlarged heart and water in his lungs.

Haim was undergoing treatment for prescription drug addiction at the time of his death, said the actor’s agent, Mark Heaslip, and had not taken any pills for a year.
