On the night of April 11, 2012, Qu and Wu stayed late at the University of Southern California, separately studying for projects at the library. At about 1:00 a.m., Bolden and Barnes approached the car, openly wielding firearms. Qu managed to get out of the car and run to a nearby home where he pounded on the door but was shot several times in the head. Wu was killed by a single shot to the chest while she was sitting in the front passenger's seat. At the time of the shooting, it was raining heavily, creating challenging conditions at the crime scene. Qu and Wu were both taken to
California Hospital Medical Center in downtown Los Angeles, where they were both pronounced dead on arrival. On May 18, 2012, tracking of the device led to the arrest of Bryan Barnes, 20 years old, who was living near USC's campus in the South Los Angeles area. A second suspect, 19-year-old Javier Bolden, a resident of
Palmdale, was detained that day. They were both charged with two counts of murder. Bolden and Barnes were also charged with attempted murder in an unrelated shooting in December 2011 at a party in South Los Angeles, which left a woman seriously wounded and a man
paralyzed. Officials also suspect Barnes of firing multiple rounds at a party on February 12, wounding a 20-year-old man. ==Aftermath==
