Crimes That Shook Britain (2008)

S9E6 Lee Pomeroy

A seemingly innocent father-son journey to the capital turned tragic when 51-year-old Lee Pomeroy was mercilessly attacked on a commuter train. In a shocking act of violence, he was stabbed 18 times within just 25 seconds, succumbing to his injuries in front of his 14-year-old son. The assailant, previously known to law enforcement and mental health services, fled the scene as British Transport Police launched a manhunt. Once captured, it became the responsibility of investigators to demonstrate that Lee's murder was both ruthless and unprovoked.
