LOS ANGELES, California (CNN)  -- One of two doctors charged with conspiring to furnish drugs to Anna Nicole Smith before her fatal overdose in 2007 surrendered to authorities and was jailed Monday, authorities said. Anna Nicole Smith's boyfriend Howard K. Stern was among those charged last week. Dr. Khristine Eroshevich surrendered at the Van Nuys, California, jail, said police and jail officials. Bail was set at $20,000, but Eroshevich had not posted bail as of Monday afternoon. Eroshevich was charged last week along with Howard K. Stern, Smith's longtime partner and attorney; and Dr. Sandeep Kapoor. Stern and Kapoor were arrested and released from a Los Angeles County jail Thursday night after each posted a $20,000 bond.
