TMZ has learned the California Department of Justice (DOJ) is conducting a criminal investigation into several doctors who prescribed various medicines to Anna Nicole Smith.
Sources tell TMZ the DOJ's Bureau of Narcotics Enforcement has contacted Larry Birkhead, Big Mo (Anna's bodyguard) and others. We're told DOJ is particularly interested in two doctors -- Khristine Eroshevich and Sandeep Kapoor. TMZ broke the story that Dr. Kapoor prescribed methadone to Anna under an assumed name when she was eight months pregnant. Dr. Eroshevich ordered a virtual pharmacy of drugs for Anna, five days after her son Daniel died.
Dr. Eroshevich, who was in the Bahamas with Anna, sent the prescription wish list to Dr. Kapoor. Kapoor's attorney, Ellyn Garofalo, told TMZ "Dr. Kapoor declined the request for prescriptions. He would never prescribe that combination of drugs, in such large dosages, to any patient."
The Medical Board of California launched its own investigation of the two doctors earlier this year. That investigation is pending.
By the way, TMZ has learned Dr. Kapoor is in the process of having twins via a surrogate.
