Karen McDonald, the prosecutor, was reported as saying there was “an additional piece of evidence that hasn’t been released yet”, after detailing a “mountain of digital evidence” against the accused on Wednesday. Reports meanwhile alleged that he wrote on Instagram: “Now I become death – destroyer of worlds – see you tomorrow Oxford.” Oakland County Sheriff Mike Bouchard said a meeting had been arranged by Oxford High School with Mr Crumbley’s parents hours before the attack because of the 15-year-old’s “concerning” behaviour but was allowed to remain in school. Fox2 Detroit meanwhile reported that the school in fact summoned Mr Crumbley’s parents on both Monday and Tuesday, citing violent drawings as well as “concerning” behaviour.
