Corey Haim Death Investigation: 20 Doctors Subpoenaed

The L.A. County Coroner's office confirms that they have subpoenaed the medical records from 20 doctors as they continue their probe into the death of Corey Haim.

According to the coroner's office, he had obtained drugs using prescriptions written under the names of the 20 doctors whose records they've subpoenaed.

The late actor is linked to an investigation into a prescription drug ring, as an unauthorized prescription in Haim's name was found during an investigation into fraudulent prescription pads, according to California's Attorney General.
