LOS ANGELES (MCT) — The University of Southern California and the Los Angeles Police Department announced sweeping new security measures Thursday, including the addition of 30 police officers to the area surrounding the campus.

The move comes three weeks after the university was stunned by the slayings of two graduate students from China, a case that remains unsolved. The measures go beyond more police on the street to include the sharing of crime data with USC public safety officials, the installation of more security cameras and the addition of a city prosecutor who will focus on cases in and around the campus.
