On Tuesday afternoon, Jesse Van Rootselaar, an 18-year-old, stole two firearms from his home and, according to authorities in British Columbia, fatally shot his mother and 11-year-old brother. He then traveled a mile to Tumbler Ridge Secondary School, where he killed five students and an educator before taking his own life. This mass shooting, which also left two children injured by gunfire, has shocked all of Canada where such extreme violence is infrequent, and has devastated the small rural community of 2,400 residents.

An investigation into Van Rootselaar's online life reveals a chronicle of his gradual descent into mental health crises and radicalization towards extreme violence. His online presence suggests a teenager who transformed from one fascinated with firearms to abusing a range of prescription and illegal drugs, eventually venturing into some of the darkest corners of the internet, where he consumed and interacted with violent content.

This horrific incident raises significant concerns about mental health and the influence of online extremism, underscoring the need for addressing the factors that may lead young individuals to commit such acts of violence. The community's response and the broader national discourse on gun control and mental health resources will certainly be critical in the aftermath of this tragic event.
