University of Southern California Grad Student Charged With Drugging and Raping

A University of Southern California graduate student who police say is a serial sexual predator has been charged with drugging and raping multiple women as investigators look for additional victims, Los Angeles authorities said.

Sizhe Weng, a 30-year-old Chinese national also known as Steven Weng, was arrested Aug. 28, though the district attorney and police just released statements about the case on Wednesday.

Weng has pleaded not guilty to eight felony counts including forcible rape and sodomy by controlled substance or anesthesia, according to the LA County District Attorney’s Office.
