Teacher murder: Police did not ask pupils why they didn't report classmate's plan to kill

None of the children who heard Will Cornick boast that he was going to kill Spanish teacher Ann Maguire has ever been quizzed about why they did not tell anyone.
The inquest into Mrs Maguire’s death heard how, in the classes immediately before the tragedy, Cornick told 10 other pupils what he was going to do to the teacher and also his plan to kill other members of staff.
