Source-derived summary

On November 4, 2015, 18-year-old student Faisal Mohammad stabbed and injured four people with a hunting knife on the campus of the University of California, Merced, in Merced, California. He was subsequently shot and killed.

Attack

The attack began at about 8:00 a.m. Pacific Time, and was over in about fifteen minutes. The first attacks took place near the center of campus, inside a classroom at the Classroom and Office Building, then continued outside the building until Mohammad was shot by UC Merced police officers. Two of the victims were airlifted to hospital; two were treated on campus for minor injuries.

Merced County Sheriff Vern Warnke stated that the weapon used in the attack was a hunting knife between 8 and 10 inches in length.

The planned attack (see below) was thwarted by a student, Tyler Patton, and construction worker, Byron Price, who was working in a nearby hallway. During Mohammad's initial attack, Patton attacked him with classroom furniture, disrupting the attack. Mohammad then tried to flee the room and ran into Price as Price was entering.
