Accused Oxford High School shooter Ethan Crumbley plans to plead insanity in the criminal case accusing him of killing four students and wounding six others and a teacher during a Nov. 30 attack, according to a court filing Thursday.
Crumbley, 15, a sophomore at the high school, has pleaded not guilty to accusations he committed the nation's deadliest school shooting since 2018.
A one-sentence notice of insanity defense was filed early Thursday in Oakland Circuit Court, signed by defense attorneys Paulette Michel Loftin and Amy Hopp. Neither have returned telephone calls.
