Psychiatrist Khristine Eroshevich, who is charged with conspiracy for allegedly funneling drugs to Anna Nicole Smith in the years leading up to her death from an accidental prescription medication overdose, turned herself in on Monday.

According to police spokeswoman Rosario Herrara, Eroshevich presented herself at the Van Nuys police station shortly after 11 a.m. She was released several hours later after posting $20,000 bail. For six months prior to her death, Khristine Eroshevich, a licensed psychiatrist who practices in Anaheim and Los Angeles, treated the 39-year-old reality TV star following the death of her son, Daniel.

Eroshevich was the third person to be charged in the case, alongside Smith's boyfriend and attorney, Howard K. Stern, and another of her doctors, Sandeep Kapoor. They were charged with "unlawfully prescribing a controlled substance" and conspiring to "commit the crimes of prescribing, administering and dispensing controlled substances to an addict," according to the offices of the California attorney general and the Los Angeles County district attorney.

Both Stern and doctor Sandeep Kapoor, who was famously photographed with Smith on a float in a gay pride parade, were booked last week and released on $20,000 bail each.

According to reports, Attorney General Jerry Brown said that Stern was the "principal enabler" in the alleged conspiracy. The doctors wrote prescriptions in fictitious names and prescribed unwarranted amounts of highly addictive medications to Smith, knowing that she was an addict.

Smith, 39, was found dead in her hotel room in Hollywood, Florida, on Feb. 8, 2007, of an accidental overdose of methadone, antibiotics, anti-anxiety medication and other drugs, shortly after the birth of her daughter and death of her son, who also died of a drug overdose.
