Calif. doctor pleads not guilty in patient deaths

LOS ANGELES (AP) -- A California doctor has pleaded not guilty to charges of second-degree murder in the prescription drug overdose deaths of three patients.

Dr. Hsiu-Ying "Lisa" Tseng wept profusely during Friday's arraignment in Los Angeles Superior Court, where the judge decided to keep her in jail in lieu of $3 million bail.

Tseng is charged with 21 other counts in addition to the deaths involving painkillers.

The Drug Enforcement Administration says Tseng wrote more than 27,000 prescriptions over a three-year period starting in January 2007 -- an average of 25 a day. The three patients who died were otherwise healthy men in their 20s who came to her with complaints of pain and anxiety.

The defense sought a quick preliminary hearing, but the earliest date available was April 30.
