Wrongful conviction of Peter Sullivan

Peter Sullivan is a British man who was wrongfully convicted of the murder of Diane Sindall in 1987. He served 38 years in prison before being exonerated by DNA evidence on 13 May 2025, at the age of 68. He is the longest-serving known victim of a miscarriage of justice in British history. As of 2026, the identity of the murderer is unknown, with him believed to be a serial rapist who operated around the area, known as The Beast.

Murder and investigation
On the morning of 2 August 1986, the body of 21-year-old Diane Sindall, of Seacombe, Merseyside, was found half-naked in an alleyway off Borough Road in Birkenhead. Her head and face had been beaten with a blunt object, theorised to have been either a crowbar or a carjack, she had been stabbed repeatedly in the chest and genitals, and had been raped. Large sections of her body had been mutilated when the attacker bit her. The night before, Sindall had left The Wellington Hotel in Bebington where she was working as a barmaid to save money for her forthcoming wedding. She had intended to drive home, but ended up walking along Borough Road after running out of fuel in Birkenhead. Sindall was seen walking along Borough Road near the Mersey Tunnel by passing drivers, with the last known individual seen with her was a man of a similar age, walking backwards and speaking with her, with Sindall seeming uncomfortable. He was wearing a leather jacket, jeans, and had a haircut similiar to a crew cut. This is believed to be the only sighting of the serial rapist and murderer known as "The Beast of Birkenhead". Witnesses reported hearing screaming, and seeing and hearing a couple arguing, between midnight and 2am on 2 August. Sindall had sustained a fractured skull and injuries to her face consistent with being beaten repeatedly with a blunt object, and had been sexually assaulted, with mutilation of the breasts and lacerated genitals. It was thought that Sindall had remained alive for some time after the attack. The cause of death was brain haemorrhage, probably caused by multiple blows to her head. The murder caused revulsion, fear and anger in Merseyside, with many women afraid to be out alone on the streets. The murder investigation which followed was the largest in the history of Merseyside Police. == Arrest and conviction ==
Arrest and conviction
Sullivan, an unemployed labourer from Birkenhead, was arrested on suspicion of Sindall's murder on 23 September. He was arrested on circumstantial evidence; he reportedly gave conflicting statements to his whereabouts on 1 and 2 August. According to Sullivan, while in custody he was beaten, denied food, sleep and legal representation, and threatened with rape charges if he did not confess. On 24 September, he reportedly broke down in tears and confessed to the murder before withdrawing the confession. Sullivan pleaded not guilty, but was convicted and sentenced to life imprisonment with a minimum term of 16 years. He continued to maintain his innocence throughout his imprisonment. == Exoneration ==
Exoneration
In 2008 the Criminal Cases Review Commission (CCRC) rejected an application for Sullivan's conviction to be reviewed, saying that there was little chance that new DNA evidence could be recoverable from the stored forensic samples. Sullivan's application to the Court of Appeal in 2019 was also rejected. In May 2025, Sullivan's conviction was quashed in the Court of Appeal by Lord Justice Holroyde, Mr Justice Goss, and Mr Justice Bryan; he became eligible for immediate release from prison, at the age of 68. Merseyside Police are now investigating the DNA profile, which does not match anyone from Sindall's family nor her fiancé. They plan to request samples from other people who were investigated during the original investigation. Sullivan is the longest-serving known victim of a miscarriage of justice in British history, having served 38 years in prison before being released at the age of 68. However, UK legislation requires that he must still prove that he is innocent "beyond reasonable doubt" if he wishes to claim compensation from the government. Labour MP Kim Johnson, the chair of the all-party parliamentary group on miscarriages of justice, called for an independent inquiry into the case. == Renewed search ==

In January 2026, a £20,000 reward was offered for information leading to a conviction of Sindall's killer. == See also ==
