In a manifesto on the eve of his massacre, school shooter Ethan Crumbley proclaimed, “There is no God. … I am the demon … I’m gonna open fire on everyone in the hallway.”

Months later in jail, he cried out: “Why didn’t you stop it, God? Why didn’t you stop it when it happened? … I’m sorry, God!”

These two versions of Crumbley were portrayed in court Tuesday during a hearing to determine whether life in prison without the possibility of parole is an appropriate sentence for the teenager accused of killing four classmates and injuring seven others in the 2021 mass shooting at Oxford High School in Michigan.

Ethan Crumbley having ‘a break with reality’

The hearing, which adjourned Tuesday until Aug. 18, included never-before released video of Crumbley in jail, where he is seen strapped to a chair in a highly distressed state, jerking about. He is wearing a hood designed to protect jail workers from spit. In another video, he is heard blaming God and crying out in distress repeatedly, “He could have stopped it” and “He could have saved her,” while authorities try to calm him down.

According to a psychological expert who testified on behalf of the defense, the video highlights the mental illness that Crumbley long battled without any help.

“What we just witnessed — someone saying, ‘God, why didn’t you stop it?’ That’s exactly how psychosis works,” psychologist Colin King testified. “Somehow you don’t understand the outcome of the consequences. He’s having a panic attack and a break with reality.”
