Investigators have conducted DNA tests on over 600 men in their efforts to solve a brutal murder case that dates back 40 years, during which an innocent man spent nearly four decades in prison.
A man named Peter Sullivan, then 30 years old, was wrongly accused of the murder of Diane Sindall, a 21-year-old florist, on August 2, 1986, being labeled as the “Beast of Birkenhead” and “Wolfman.” His conviction was overturned last year after he claimed to have made a false confession under duress from Merseyside officers.
Following the relaunch of the investigation in 2023, new DNA evidence from samples found at the crime scene identified a male match, prompting continued efforts, including collaboration with the National Crime Agency to determine the individual linked to the DNA profile.
A Crimestoppers reward of up to £20,000 remains available for information leading to the arrest and conviction of the person responsible for Diane’s murder.
Detective Superintendent Rachel Wilson, leading the inquiry, emphasized the ongoing commitment to solving the case and bringing closure to Diane’s family and the public. The investigative team has been meticulously reviewing the original case, re-interviewing witnesses, conducting DNA tests, and following up on public tips.
Wilson stressed the importance of the DNA profile in identifying the killer, with 575 individuals eliminated so far and 32 still under review. She urged anyone with information about the case to come forward, emphasizing the significance of cooperation in achieving justice.
The tragic events leading to Diane’s murder unfolded as she was returning home after a part-time shift, only to be found beaten to death hours later in an alleyway. The case sparked a massive manhunt, culminating in Sullivan’s arrest, based on conflicting statements and alleged proximity to the crime scene.
Sullivan’s trial in 1987 centered on bite mark evidence that linked him to the crime, earning him the infamous nickname “Wolfman.” His eventual release was facilitated by a DNA sample analysis method introduced in 2015.
Expressing remorse for the victim’s family, Sullivan offered his support in seeking justice and closure, pledging to stand by them throughout the legal proceedings against the true perpetrator.
