Officials with Michigan’s Oxford High School should have conducted a threat assessment into Ethan Crumbley's behavior prior to a shooting that left four students dead and others wounded, an independent investigation concluded.
Crumbley's conduct included viewing bullets, watching violent video on his cellphone during class, and writing statements like “blood everywhere,” a more than 500-page report said. That suggested “not suicide, but homicide,” according to the report released Monday, a month shy of the two-year anniversary of the Nov. 30, 2021, shooting.
