Faisal Mohammad, 18, appears to have become self- radicalised, drawing motivation from terrorist propaganda that he found online before launching the November 4 attack at the University of California, Merced, authorities said yesterday.
"Every indication is that Mohammad acted on his own," Gina Swankie, a spokeswoman for the FBI's Sacramento field office, said in a statement. "It may never be possible to definitively determine why he chose to attack people on the UC Merced Campus."
In that case, too, investigators said they were influenced by the Islamic State group, but not directly connected to it. Like Mohammad, they had not raised red flags that put them on a watch list.
In both cases family members said they were unaware of their loved ones' interests in terrorists groups.
In Merced, Mohammad burst into a classroom, stabbing two students. He stabbed a construction worker who intervened, then ran from the building, where he knifed a school employee sitting on a bench. Police shot and killed Mohammad.
During the rampage, Mohammad carried a backpack containing a two-page, hand-written manifesto detailing plans to bind students to their desks with zip-tie handcuffs, authorities have said. Then, he was going to make a fake 911 distress call, ambush responding officers with a hunting knife and steal their guns to shoot a list of targeted classmates.
Mohammad's backpack also held a photocopy of an Islamic State group flag and a list of items he would need for the attack, the FBI said.
