In a bid to solve a 40-year-old murder case, detectives have conducted DNA tests on over 600 men. This investigation aims to uncover the truth behind a brutal crime that led to the wrongful imprisonment of an innocent man for 38 years.
Peter Sullivan, then 30 years old, was wrongly accused of murdering 21-year-old florist Diane Sindall in a frenzied sexual assault on August 2, 1986. He was dubbed the “Beast of Birkenhead” and “Wolfman” during this ordeal.
Following his release last year, after asserting that he had given a false confession due to mistreatment by Merseyside officers, the authorities have reignited their efforts to apprehend the actual perpetrator before the anniversary of the tragic event.
The investigation into the Wirral murder case was reopened in 2023 when DNA tests matched a male profile from samples collected at the crime scene. Collaborating with the National Crime Agency to identify the individual linked to the DNA profile, the inquiry is still ongoing.
A reward of up to £20,000 offered by Crimestoppers for credible information leading to the arrest and conviction of Diane’s murderer is still valid and open exclusively to the charity.
Detective Superintendent Rachel Wilson, heading the investigation, expressed determination to bring closure to Diane’s family and the public by relentlessly pursuing the elusive killer. The investigative team has meticulously reviewed past leads, re-interviewed witnesses, conducted DNA analyses, and followed up on new tips from the community.
Wilson emphasized the importance of the DNA profile in solving the case, highlighting the elimination of 575 individuals from suspicion while 32 others are under current review.
Appealing to potential witnesses or informants, Wilson encouraged anyone withholding information out of fear or misplaced loyalty to come forward and assist in bringing justice to Diane’s memory.
Diane, a part-time pub worker in Bebington, tragically met her demise while heading home after her shift. Her life was cut short in a brutal attack as she walked along a well-lit road towards Tranmere, sparking a massive police investigation.
Discovered by a passerby in an alleyway, Diane had suffered severe injuries consistent with a violent sexual assault, resulting in her tragic death. The case garnered significant media attention and led to Sullivan’s arrest, based on conflicting accounts of his whereabouts.
Sullivan’s trial in 1987 featured dental evidence linking him to bite marks on Diane’s body, contributing to his wrongful conviction known for the infamous “Wolfman” reference.
The breakthrough in Sullivan’s case, leading to his exoneration, came from DNA evidence utilizing modern technology not available during the original investigation. Sullivan expressed remorse for Diane’s family and offered support in their pursuit of justice.
