St. Pius X High School was the scene of one of North America's first school shootings. On October 27, 1975, student Robert Poulin went on a shooting spree in the school. Poulin, an 18-year-old St. Pius student, opened fire on his classmates with a shotgun killing one and wounding five before turning the gun on himself and committing suicide. Poulin had raped and stabbed his 17-year-old friend Kim Rabot to death prior to the incident. A book entitled Rape of a Normal Mind was written about the incident.
