Heath Ledger, 28, was found dead in his apartment in New York on Jan. 22. The autopsy results of New York City’s Chief Medical Examiner blamed his death on accidental mixture of prescription drugs.
The Federal Drug authorities want to check with the two doctors in California and Texas to see whether they prescribed the drugs legally
according to People magazine.
The agents have not yet given their findings, but they are expected soon according to a source connected to Federal Drug authorities. The doctors are supposed to have supplied Ledger with OxyContin and Vicodin drugs.
The autopsy also found other drugs in addition OxyContin and Vicodin (Hydrocodone), such as Diazepam (Valium), Temazepam (for anxiety or sleeplessness), Alprazolam (Xanax) and Doxylamine (sedating antihistamine for aiding sleep).
