The violence began inside a classroom at the Classroom and Office Building, near the center of UC Merced's compact campus. Faisal Mohammad, an eighteen-year-old freshman from Santa Clara who had graduated from Wilcox High School just months earlier, attacked a fellow student with a hunting knife measuring eight to ten inches. Another student in the room, identified only by the last name Patton, fought back with what was available - classroom furniture - disrupting the assault and likely preventing worse injuries. Mohammad tried to flee the room and collided with Byron Price, who was entering from the hallway. Price was stabbed in the side. Mohammad then ran down the stairs and out of the building, attacking a university staff member outside and stabbing her several times. He fled across the Scholar's Lane pedestrian bridge at the center of campus, where two UC Merced police officers intercepted him. They gave chase and shot him dead on the bridge.

Price's account of the encounter is striking for its specificity. He described Mohammad as looking scared during the attack, but said he also "looked like he was having fun. He was smiling." Price did not retreat after being stabbed. He tried to confront the attacker, an act that drew immediate public recognition. The California State Legislature gave him and Patton a standing ovation in Sacramento in February 2016. All four stabbing victims - two students, one staff member, and Price - suffered non-life-threatening injuries and recovered fully, with no lifelong effects. In a campus attack where the outcome could have been catastrophic, the combination of a resistant student, an intervening bystander, and a rapid police response compressed the violence into minutes rather than hours.

When investigators searched Mohammad's body, they found a handwritten manifesto detailing plans far more elaborate than what he carried out. He had intended to use duct tape and zip-tie handcuffs to bind students to their desks, then call police and steal a responding officer's gun. His backpack contained the zip ties, two rolls of duct tape, petroleum jelly he planned to spread on the floor to make officers slip, a night-vision scope, and a safety hammer for breaking windows. The manifesto's target was specific: students who had excluded him from a study group. Merced County Sheriff Vern Warnke initially characterized the attack as a personal vendetta with no connection to terrorism, noting that although the manifesto referenced Allah, the motivation appeared to be social rejection. But new information emerged within days, and on November 7 the Sheriff's Department transferred formal control of the investigation to UC Merced and the FBI.

On March 17, 2016, the FBI concluded its investigation and classified the attack as an act of lone-wolf terrorism inspired by ISIS. Investigators found ISIS propaganda on Mohammad's computer and evidence that he had visited extremist websites in the days before the stabbing. His manifesto included plans to behead a victim - a signature element of ISIS propaganda videos circulating at the time. The FBI stated categorically that it had no prior knowledge of Mohammad and that he had never been the subject of a federal investigation. His roommate later described him to investigators as "a loner and an extreme Muslim," adding that he was not surprised by what had happened. The roommate recalled an incident in which a friend had jokingly asked Mohammad what would happen if he touched his prayer mat. Mohammad's response: "I will kill you." Whether the attack was primarily driven by ideology or by the social isolation that made ideology appealing remains a question the investigation did not fully resolve. The FBI's classification settled the legal matter; the human one remains more complicated.

UC Merced opened in September 2005 with 875 students on a former cattle ranch adjacent to Lake Yosemite. By November 2015, it was still the newest and smallest campus in the UC system, still proving itself in a region where many residents had never had access to a research university. The stabbing arrived at a fragile moment. Just weeks after the attack, the UC Regents approved a $1.14 billion expansion plan to double the campus's capacity. The university continued to grow - enrollment surpassed 9,000 by 2023, and in 2025 UC Merced achieved R1 Carnegie research classification, the highest tier of research activity. The attack became a chapter in the campus's early history rather than its defining story. But for Price, for Patton, for the staff member stabbed outside the building, and for every student who crossed the Scholar's Lane bridge that morning, fifteen minutes was enough to change everything.
