MERCED —

Investigators say a two-page handwritten manifesto found on the dead body of UC Merced stabbing suspect Faisal Mohammad indicated he was angry at students after being kicked out of a study group and planned to do much more damage on campus.

“His plan went haywire because people fought back. And that was his bad luck,” Merced County Sheriff Vern Warnke said.

The Merced County Sheriff’s Department said Mohammad stabbed four people on campus early Wednesday morning.

They say the attack started inside of a second-floor classroom, where Mohammad stabbed a student and a contractor. They say he then stabbed another student in a stairwell, before stabbing the fourth victim, a staff member while running from that building. Once outside, police fatally shot Mohammad.

Warnke said Mohammad planned to zip-tie students to their chairs, and stab a police officer and steal his gun. He said Mohammad’s backpack found at the crime scene contained those zip-ties, along with a night vision scope, a hammer, duct tape and petroleum jelly.

“The petroleum jelly. He planned to cut a hole in the bags of it and squirt it onto the floor of the classroom. As a sort of slip-and-slide. He was gonna use that to make an entrance problem for anybody that came into that room, if they made it that far,” Warnke said.

Students who knew Mohammad told FOX40 he was always building barriers between himself and others.

“I tried to talk to him. I mean there was time after time after time I would try to have conversation with him inside his dorm room. I only ever saw him outside the dorm one time. But he never reciprocated,” Robert Tran said.

Tran lives in the same “Tuolomne” dorm building that Mohammad lived in, he says just three doors separated them.

“The issue was lack of communication and lack of connection for him. which is contrary to their belief that it was like a terrorist attack,” Tran said.

But some people felt they had reason to question a terrorist attack.

“There was a couple references to Allah,” Warnke said.

Warnke clarified that the manifesto’s few references to Allah only referred to Mohammad’s belief in a higher power.

“Well, at least I tried. All I could do was try you know? He just didn’t try back,” Tran said.
