Families of victims in a February school shooting in Canada filed lawsuits Wednesday morning alleging that OpenAI and its CEO, Sam Altman, were complicit in the gunman’s planning to carry out the attack that killed eight people. 

The lawsuit stems from a shooting in Tumbler Ridge, British Columbia, in which 18-year-old Jesse Van Rootselaar, who police said was biologically male and transitioned to female, killed six children and two adults before dying of a self-inflicted gunshot wound.
