On 13 May 2025, Peter Sullivan, now 68, walked free from court after the Court of Appeal quashed his 1987 murder conviction—closing one of the most harrowing chapters in British legal history. He had spent 38 years behind bars for the murder of 21-year-old Diane Sindall in Birkenhead, Merseyside, a crime he always insisted he did not commit.
The case was overturned after new DNA evidence emerged, definitively excluding Sullivan as the perpetrator. The court's ruling marks what many legal experts have called one of the longest-running miscarriages of justice in the UK. For Sullivan, it ends decades of waiting. For Diane's family, the question of who really killed her still remains painfully unanswered.
