The Bill

When Justice Isn't Enough (Part 2) (21x95)

:

Powell's death sends shockwaves through the team. Morrell initially suspects Josh Hill of being involved when CCTV shows him speaking to Powell shortly before the murder, but DNA evidence soon rules him out. Suspicion then falls on barman Michael Keanan, who gave Powell a lift home, but again DNA evidence rules him out. The focus soon switches onto John Lord, whom Manson identifies as the man who tried to interrupt Keanan's initial interview. Hunter manages to connect a further incident previously investigated by Valentine and Kapoor to the killer, where a young man was tied up and bound to his bed, but survived after the attacker was spooked by a phone call.
