Dr. Khristine Eroshevich, a psychiatrist to Anna Nicole Smith
, was booked Monday on seven felony charges for allegedly conspiring with another doctor and Smith's boyfriend to prescribe excessive drugs under fake names.
Eroshevich, 61, who also was Smith's neighbor in Studio City, Calif., traveled extensively with Smith before her death in February 2007 of an accidental drug overdose.
Last week, the psychiatrist was charged
along with Howard K. Stern, 40, and Dr. Sandeep Kapoor, 40, with participating in a conspiracy to furnish the former Playmate with toxic drugs – including methadone, chloral hydrate and clonazepam – often by using fake names or by prescribing the drugs to Stern.
Bail for all three was set at $20,000 each, and arraignment is scheduled for May 13. Stern and Kapoor turned themselves in Thursday night in Whittier, Calif., posted bail and were released. Eroshevich surrendered at the Los Angeles police station in Van Nuys, Calif.
Adam Braun, an attorney for Eroshevich, says his client committed no crimes.
"Anna was the center of a cruel tabloid feeding frenzy," Braun says. "In the face of this, Dr. Eroshevich did her best to help the patient while protecting what little privacy Anna had left. Any actions were done with the patient's well-being in mind and were certainly not criminal."
