Prosecutors say Smith's lawyer and boyfriend Howard K. Stern, 40, her psychiatrist and neighbor, Khristine Eroshevich, 61, and her physician, Sandeep Kapoor, 41, fed a steady stream of deadly drugs to the famous model, who died two years ago at age 39.
"I do find the proof is sufficient to bind them over for trial," Los Angeles Superior Court Judge Robert J. Perry ruled as he brought the trio's preliminary hearing to a close Friday.
Stern is charged with 11 felony counts, including prescribing a controlled substance to an addict; obtaining a prescription by deceit; fraud and conspiracy. Eroshevich and Kapoor each face six felony counts.
Witnesses who testified during the preliminary hearing included a pharmacist who said that he refused to fill a prescription written by Eroshevich because the high doses of medication amounted to "pharmaceutical suicide."
Also in court, a witness read the following from a June 13, 2005 entry in Kapoor's journal: "I was making out with Anna, my patient, blurring the lines ... I gave her methadone, Valium. Can she ruin me?"
The three defendants return to court Dec. 11.
