Michael Slobodian, a 16-year-old student at the school, had been cutting classes, and teacher Margaret Wright had called his parents to inform them of the issue.

"[1] Ross Bronson was a physics teacher who had recently vetoed one of Slobodian's entries in a science fair.

[3][4] He began by firing at three boys in a washroom, killing fellow student John Slinger and wounding the other two.

Another witness was Scott Thompson, of the Kids in the Hall, who was in the same English class with Slobodian that was taught by Wright.

[5] Thompson has stated that the 24-year-old Wright, who was six months pregnant, had been his favourite teacher and the first person to encourage his writing talents.
