Family's Heartfelt Appeal to Identify Real Killer After DNA Clears Wrongly Convicted Man
The family of a young woman who was brutally raped and murdered nearly four decades ago have made an emotional public appeal to help catch the true 'Beast of Birkenhead.' This comes after a man who was wrongly imprisoned for 38 years was exonerated by advanced DNA evidence, marking the longest miscarriage of justice in British history.
The Tragic Night of August 2, 1986
Bride-to-be Diane Sindall, a vibrant 21-year-old, was ambushed, sexually assaulted, and violently beaten to death after her car ran out of petrol just after midnight in Birkenhead, Merseyside. She had just finished a shift at her part-time job at the Wellington Pub in Bebington, Wirral, where she worked to save extra money for her upcoming wedding to childhood sweetheart David Beattie.
Driving home in her distinctive blue Fiat van, she was forced to abandon the vehicle and was seen walking along Borough Road in Birkenhead town centre between midnight and 12.20am. Witnesses described her wearing a striking white blouse with large green polka dots. Police believe she was either heading to a garage for petrol or trying to find a bus stop to return home to Wallasey, where she lived with Mr Beattie and their pet Labrador.
A Brutal Discovery and Initial Investigation
Tragically, Diane never made it home. Her half-naked, mutilated body was discovered twelve hours later in a town centre alleyway by a dog walker. She had suffered a fractured skull, cuts to her breasts and genitals, and vicious bite marks during the attack. Items of her clothing and a bank paying-in slip were found fifteen days later, burnt in a small fire near Bidston Hill, approximately two and a half miles from the murder scene. A witness reported seeing a man running away from that spot less than twenty-four hours after the murder.
The brutal killing sent shockwaves through the local community, leaving women terrified. Initially, police investigations drew a blank until several weeks later, following an appeal on the BBC's Crimewatch, Peter Sullivan was arrested. Sullivan, then aged 30 and a petty criminal with learning difficulties, was placed near the scene by witnesses, and dental impressions seemed to match bites on Diane's body. After giving confusing accounts, he confessed to the crime but later retracted his statement, claiming he was bullied and beaten by officers into admission.
DNA Evidence Overturns Conviction
Peter Sullivan was sentenced to life in prison in November 1987 but was repeatedly denied parole because he refused to admit responsibility. Last year, advances in forensic science revealed that his DNA was not present in semen samples recovered from the crime scene, leading to his conviction being quashed in May. He was freed after spending 38 years behind bars, expressing deep sympathy for Diane's family and offering to support them in court if the real killer is found.
Merseyside Police have now reopened the investigation, working with the National Crime Agency and employing the latest familial DNA techniques to identify the perpetrator. Detective Superintendent Rachel Wilson, leading the inquiry, believes the killer is a local man with knowledge of the Bidston Hill area, as evidenced by the disposal of Diane's clothing there. She also suspects that a 17-year-old girl sexually assaulted on Borough Road the same night was attacked by the same individual.
Renewed Appeals and Community Efforts
A £20,000 reward has been offered for information leading to the arrest and conviction of the killer. As part of a new BBC Crimewatch Live appeal, Diane's family have urged anyone with information, no matter how small, to contact Merseyside Police. In a heartfelt statement, they described Diane as a 'beautiful soul' full of love and laughter, whose future was cruelly stolen. They emphasized the enduring heartache and the need for closure.
Police are seeking a man seen arguing with a woman, believed to be Diane, on Borough Road that night. He was described as white, in his 20s, around 5ft 10ins tall, wearing a brown leather jacket and blue baggy work jeans. Some locals and members of RASA Merseyside, a charity established in Diane's memory to support rape and sexual abuse victims, suggest that residents of tight-knit communities may have known the killer's identity but feared repercussions.
Detective Superintendent Wilson has made a direct appeal to the public, urging anyone with knowledge to come forward. She stated that officers will leave 'no stone unturned' to bring the perpetrator to justice, highlighting that DNA technology was in its infancy in 1986 and is now a crucial tool in the reinvestigation. A poignant stone memorial at the murder site, adorned with flowers and teddy bears since 1988, stands as a testament to Diane's memory and the ongoing quest for truth.
