Jackie Malton revisits the case of Scottish serial killer Peter Tobin, who had a criminal record dating back to his childhood. She travels to Glasgow to meet officers, forensic scientists, and the legal team who were instrumental in putting him behind bars – most have never talked about these cases before. British original true crime series “The Real Prime Suspect” – Tuesdays 10pm only on CBS Reality. I filmed the B camera for four days on this job.
