The student who wounded four people last year in a campus stabbing at the University of California, Merced, was inspired by "terrorist propaganda" and had visited websites related to the Islamic State in Iraq and Syria (ISIS), according to an FBI investigation.
"Investigators developed information that he may have self-radicalized and drawn inspiration from terrorist propaganda. His laptop contained pro-ISIL propaganda, and he had visited ISIL and other extremist websites in the weeks prior to his attack," according to a press release on the results of the FBI Sacramento investigation, which uses another name for ISIS.
The student had planned the attack at least a week before he carried it out and he acted alone, according to the FBI.
Investigators found a copy of an ISIS flag in the student's backpack he carried at the time of the attack. They also found a plan outlining what the student wanted to do. His plans included taking hostages and killing students and police officers.
"After an extensive investigation of all available evidence, no ties to co-conspirators or foreign terrorist organizations have been found. Every indication is that Mohammad acted on his own; however, it may never be possible to definitively determine why he chose to attack people on the UC Merced campus," the release said.
"We are relieved to finally have a resolution to this very tragic event," Dorothy Leland, the school's chancellor, wrote in a statement.
“I am proud of the way our campus community came together in the aftermath of this incident, and the kindness displayed by so many only reinforced what I already knew to be true about UC Merced. Now, we move to the task of further healing and taking care of the needs of our students, staff and faculty.”
