The amount and combination alarmed the pharmacist, who later recalled thinking, 'They are going to kill her with this.' He phoned Smith's internist and said he had no intention of filling a prescription that amounted to 'pharmaceutical suicide.' Less than five months later, on Feb. 8, 2007, 39-year-old Smith overdosed on prescription medication in a Florida hotel room. The account of the pharmacist's warning is contained in recently unsealed affidavits written by state officials investigating what role Smith's physicians and a companion may have played in her drug use. The affidavits document similar admonitions from two other pharmacists and allege that Smith's psychiatrist, Dr. Khristine Eroshevich, and internist, Sandeep Kapoor, ignored obvious dangers in providing a smorgasbord of powerful and addictive drugs to a woman with a history of substance abuse. The documents also cite evidence that both doctors separately transgressed professional boundaries by having sexual contact with their patient. Los Angeles prosecutors charged the doctors and Smith's boyfriend and lawyer, Howard K. Stern, in March with conspiring to illegally provide her with controlled substances. All three have pleaded not guilty. A preliminary hearing is set for next month. In court papers filed last week, prosecutors indicated they planned to call as witnesses people close to the former Playboy Playmate, including bodyguard Larry Birkhead, the father of her daughter, Dannielynn.
