A California college student who stabbed four people at his school in November before being killed by police may have been inspired by the terror group ISIS and other extremist groups, federal investigators said Thursday, NBC News reports.
Faisal Mohammad, 18, "may have self-radicalized and drawn inspiration from terrorist propaganda" before the Nov. 4 attack at the University of California, Merced campus, the Department of Justice said in a statement.
All four people who were stabbed survived.
The Justice Department said the FBI found pro-ISIS propaganda on his laptop and evidence that he visited extremist websites in the weeks before the attack. Investigators also found a photocopied ISIS flag along with a knife and list of supplies after he was killed, the department said.
