Dr. Khristine Eroshevich Challenges Search Warrants

Lawyers for Dr. Khristine Eroshevich, the psychiatrist of Anna Nicole Smith under investigation in the Playmate's death, are challenging the validity of search warrants used in last Friday's raid on her home.

According to TMZ, the home of Khristine Erosovich was one of the locations raided by state officials as part of an investigation into the doctors who prescribed medications to Smith, who died in Florida February 8.

In L.A. County court, Erosovich's lawyers challenged the officials' search warrant as "overly broad" and requested the return of some of the psychiatrist's personal items, including CDs and DVDs that had been seized in the raid.

Attorneys for Khristine Erosovich also made arrangements to view all seized materials. We've learned the judge may appoint a Special Master to the case.

This is to ensure there was no inappropriate seizure, and analyzes material seized to determine what is protected by doctor-patient privilege and what is not.

In addition, the judge signed several additional search warrants - what those are for is not yet known. They'll be back in court December 5.

Several agencies made searches in connection with a Medical Board of California investigation into whether Anna Nicole Smith was over-prescribed medication.

Also under investigation is Dr. Sandeep Kapoor.
