A judge decided Monday that 16 year-old Eric Hainstock will be tried in adult court for the murder of his principal.

Hainstock faces life in prison if convicted. He had asked to have his trial moved into juvenile court, where he would be freed at age 25.

A criminal complaint accuses Hainstock of walking into Weston High School in September and shooting principal John Klang during a scuffle.

Hainstock's attorney says he will "rot away" in prison. She says therapy he would have received at a juvenile facility could have helped him.
