California's attorney general said he believes Corey Haim's tragic death this week is linked to a "illegal and massive prescription-drug ring" already under investigation in the state.

"Corey Haim's death is yet another tragedy linked to the growing problem of prescription-drug abuse," Attorney General Jerry Brown said Friday, according to CNN. "This problem is increasingly linked to criminal organizations, like the illegal and massive prescription-drug ring under investigation."

Even though the coroner has not ruled on what killed Haim on Wednesday, Brown's office says the the former child star's death has already played a part in their ongoing investigation into illegal prescriptions outside of Los Angeles.

The statement says "an unauthorized prescription under the former child star's name that was found during an ongoing investigation of fraudulent prescription-drug pads ordered from a vendor in San Diego."

Brown said the ring uses stolen doctor's identities to order prescription-drug pads that are used to write counterfeit prescriptions.
