NOBLESVILLE, Ind.  — A 13-year-old boy has shown no remorse for shooting his teacher and a classmate at his Indianapolis-area school, and he should be held at a state juvenile detention center until he is 18 or deemed rehabilitated, an Indiana judge ruled Wednesday.

Hamilton County Circuit Court Judge Paul Felix rejected a request from the boy’s attorneys that he be sent to a private treatment facility after he admitted shooting seventh-grade science teacher Jason Seaman and 13-year-old Ella Whistler during the May 25 attack at Noblesville West Middle School.

Felix said during the teen’s punishment hearing Wednesday that he didn’t think the boy was sincere and that no remorse was shown last week.
