Los Angeles Times reporters win Pulitzer for investigation

Three Los Angeles Times reporters have won a Pulitzer Prize for their investigation into a gynecologist accused of abusing hundreds of students at the University of Southern California.

Harriet Ryan, Matt Hamilton and Paul Pringle won the prize for their stories about Dr. George Tyndall, which started with an anonymous tip Ryan received.

In the wake of the stories, the university's president resigned, the Los Angeles Police Department launched an investigation and more than 650 women have sued USC, alleging the school failed to protect them from sexual abuse. Tyndall has denied the allegations.
