Never heard by the public until now - Dean Webber’s police interview, in the hours after the fatal stabbings, raises more confusing questions about what exactly happened. In this episode, Dean’s account is put under the microscope - challenged by the lawyer representing Tom Davy’s family, and scrutinised by Justin Luke, the officer sitting next to him in the interview room. 
Now no longer in the force, Justin Luke offers a damning insight into how police handled this case - and why this investigation may have gone so wrong.
