An ex-police officer had raised concerns about a series of sexual assaults before the brutal murder of Diane Sindall, known as the ‘Beast of Birkenhead’ case. Peter Sullivan was wrongly convicted of Sindall’s killing and spent nearly four decades in prison before being exonerated based on new DNA evidence.
On the night of August 1, 1986, Sindall, who had just finished her shift at the Wellington pub, ran out of petrol in her blue van. She was later found in an alley off Borough Road in Birkenhead, partially undressed and fatally beaten.
The former officer, who chose to remain anonymous, revealed that he had noticed a trend of similar attacks in the area leading up to Sindall’s murder, indicating a potential serial attacker. Despite his warnings to investigate, he claimed that senior detectives discouraged further inquiry, and Sindall’s tragic death occurred shortly after his concerns were raised.
Merseyside Police stated that there was no current evidence linking Sindall’s murder to other offenses in the area. However, they acknowledged the case’s ongoing review and the consideration of related crimes before and after Sindall’s death.
Recent efforts by a cold case team involving over 20 officers aim to solve the 1986 murder using advanced DNA profiling techniques. A reward of £20,000 has been offered by Crimestoppers for information leading to the arrest of the individual responsible for Sindall’s death.
Authorities are investigating a suspect described by a taxi driver as a white male in his early twenties, approximately 5ft 10in tall, with a slim build, dark hair, and wearing a dark brown leather jacket and jeans. DNA samples have been collected from various individuals across different locations to compare against the killer’s DNA found at the crime scene.
A memorial plaque dedicated to Diane Sindall stands on Borough Road, where she was killed, serving as a reminder of her tragic fate and honoring all victims of similar crimes. The BBC podcast ‘Crime Next Door: The Beast of Birkenhead’ provides further insights into this unsolved case.
