The haunted father of the victim of one of Britain’s most notorious unsolved murders has died before any suspect was ever arrested, MailOnline has learned.

The savage killing of Deborah Linsley on a suburban commuter train as it arrived at London’s Victoria station in 1988 is regularly cited as one of the UK’s most high-profile unsolved cases.

Deborah’s father Arthur, a retired insurance broker, spent more than three decades campaigning for justice for her - regularly appearing in the media to ensure her case was not forgotten and that the police continued to try to find her killer.

But now MailOnline can reveal that Mr Linsley has sadly died before anyone could ever be linked to the attack and prosecuted.

The case was particularly infuriating for detectives as they have a full DNA match for the killer - but no match has ever come up for them or any relative.
