Murder Detective with Graham Hill S01E05 - Episode 5: Dean Mayley

Dean Mayley was an innocent man with learning difficulties doing his best to become an independent adult. His newly found independence saw him become the victim of a horrific attack by four teenage boys aged 17-19 in broad daylight.

In February 2014, whilst walking home alone, Dean encountered the group, who taunted, mugged, and stabbed him with such force that the knife passed through his body and came out the other side.

Hill discusses the case with SIO Matt Bonner, who was motivated by a desire to bring justice to those involved in this extreme and cruel-natured crime. He waded through CCTV footage, undertook interviews, pressured prime suspects, and uncovered phone records until he found his culprits.
