A reputed gang member has been charged with four counts of attempted murder for allegedly opening fire outside a Halloween party on the University Southern California campus.

Twenty-year-old Brandon Spencer of Inglewood was named in a complaint filed Monday by Los Angeles County prosecutors.

Four people were wounded, one critically. The party attended by hundreds of people was sponsored by a student organization but neither the shooter nor the victims were students at USC.

The felony complaint says the shootings were committed for the benefit and at the direction of a criminal street gang. If convicted, Spencer could go to prison for life.

The shootings occurred despite a strengthening of security following the April slayings of two Chinese graduate students about a mile from the school.
