An 18-year-old University of California at Merced student smiled as he slashed at people during a stabbing spree that wounded four people on the campus Wednesday, according to a Merced man who is being called a hero for attempting to stop the attack, reports the Merced Sun-Star .
The student, identified as freshman Faisal Mohammad of Santa Clara, "looked scared," Byron Price, a 31-year-old construction worker, told the Sun-Star on Thursday.
