The accused shooter at Oxford High School, Ethan Crumbley, was in court Tuesday as a judge weighs moving the 15-year-old out of an adult jail and into juvenile hall.
Crumbley allegedly killed four classmates and injured seven others last November.
“In his journal he described the type of gun he needed… who his first victim would be… and ultimately he expressed that he would surrender so that he could witness the pain and suffering that he caused.” said Assistant Prosecutor Markeisha Washington.
Washington says Ethan also had outlined plan to rape and kill a female classmate.
The defense says the isolation Crumbley is experiencing is harmful to his mental health.
The judge is expected to issue his ruling by the end of next week.
James and Jennifer Crumbley will appear in court later this week when their preliminary hearing resumes. The couple is facing charges of involuntary manslaughter for allegedly missing red flags in their son’s behavior.
