A Rowland Heights doctor charged with murder in the overdose deaths of three patients pleaded not guilty Friday.
Hsiu-Ying "Lisa" Tseng, 42, wearing a blue jumpsuit and her hair pulled into a ponytail, was silent throughout her brief arraignment in Los Angeles County Superior Court. Before the hearing began, Tseng met with several new attorneys handling her defense.
Tseng is charged with second-degree murder in the deaths of three men and is accused of recklessly prescribing addictive drugs to patients who had no medical need for them. She is the first doctor accused of murder by the Los Angeles County district attorney's office over the prescribing of drugs.
In June, Superior Court Judge M.L. Villar de Longoria ordered Tseng to stand trial for murder, saying the evidence suggested that the doctor may have "improperly used her prescription pad to cause irreparable harm." Tseng's three-week preliminary hearing included more than 40 prosecution witnesses.
