Smith III — a college student who was attacked in the living room where she went to class last week, fatally stabbed herself in her sleep on Aug. 10 — was widely reported among teachers on Friday, a day after another high school student was stabbed and killed by a suspect on campus. The killing of the 23-year-old freshman, identified as Matthew W. Smith III of Oakdale, who was attacked Thursday is the third in as many months where a student has been killed by an intruder and the second over the last couple of months. On Friday, a student assaulted a man at a local college in California, one of three high schools in California where many students were stabbed on campuses from March 2009 to September 2014. The assailant shot the man and injured four members of the community. Jody Smith III had worked as a janitor, and had also been a janitor at the local High School two-year ago.

A week prior to her murder, a man was stabbed for no apparent reason in the cafeteria at St.
