Attorneys are set to deliver opening statements Monday in the trial of a California doctor charged with murder in the deaths of three men who overdosed on prescription painkillers.

Dr. Lisa Tseng has pleaded not guilty to three counts of second-degree murder. The 45-year-old could face up to life in prison if convicted on all charges.

Tseng is among only a handful of doctors nationwide to be charged with murder related to prescription drugs.

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. Three young men taking Tseng's prescriptions died in 2009 in Orange and Riverside counties in California and the Phoenix area.

Tseng's attorney says the deaths were not Tseng's fault.
