University spokesman James Leonard on Thursday identified Faisal Mohammad of Santa Clara as the attacker who burst into a classroom with a hunting knife. The Merced County Sheriff's Office also confirmed Mohammad's identity.
Mohammad was shot and killed by campus police Wednesday after he ran from the building. Investigators say Mohammad may have killed his intended target if not for the intervention of a construction worker who ran into the classroom to break up what he thought was a fight.
All of the victims are expected to survive. Their identities were not released.
According to a press release from the school, the victims include two students, one staff member and one construction worker. One of the students and the construction worker were treated and released. The other student remains hospitalized but is expected to recover, and the staff member suffered a collapsed lung but was recovering after successful surgery.
Mohammad was a first-year student at UC Merced majoring in computer science and engineering. His suitemate at the college dormitories, Andrew Velasquez, told ABC7 sister station KFSN-TV that Mohammad didn't talk much and kept to himself.
"Every time I would try and say something he would just ignore it," Velasquez said.
The FBI is now part of the case, which is also under investigation by the UC Merced Police Department and the Merced County Sheriff's Office.
