The killings took place in the early morning hours of April 23, 2006. Marc and Debra Richardson had forbidden their twelve-year-old daughter from continuing a romantic relationship with Jeremy Steinke, an unemployed twenty-three-year-old who belonged to a local subculture and claimed to be a three-hundred-year-old werewolf. Incensed by her parents' disciplinary boundaries, Richardson exchanged digital messages with Steinke plotting their deaths. During the assault, Steinke fatally stabbed the parents on the upper floor, while Richardson slit the throat of her eight-year-old brother in his bed.
Police arrested both perpetrators within twenty-four hours in Leader, Saskatchewan, roughly eighty miles northeast of the crime scene. The graphic nature of the crime and the cold calculation uncovered in personal emails shattered public assumptions regarding childhood violence. Trial proceedings in 2007 painted a horrifying portrait of coercive codependency, adolescent narcissism, and severe psychiatric enmeshment, forcing the Court of Queen's Bench of Alberta to reckon with an unprecedented judicial scenario.
