A Rowland Heights doctor was convicted of second-degree murder Friday in connection with the overdose deaths of three patients, capping a landmark case that was closely watched by medical professionals across the country.

Dr. Hsiu-Ying “Lisa” Tseng, the first doctor charged with murder in California for prescribing drugs to patients who fatally overdosed, was accused of ignoring “red flags” about her prescribing habits, including the overdose of a patient in her clinic and nine phone calls in less than three years from authorities informing her that patients had died with drugs in their system.

During the trial, which lasted nearly two months, Deputy Dist. Atty. John Niedermann told jurors that even after some patients — among them an undercover agent — told Tseng about their heroin addiction, she agreed to give them powerful narcotics without asking follow-up questions.
