£20,000 reward offered to catch 'Beast of Birkenhead' who murdered Diane Sindall

Key Concepts

• Miscarriage of Justice: A wrongful conviction resulting in imprisonment.
• Forensic DNA Analysis: The use of DNA profiling to identify individuals and analyze biological evidence.
• Cellmark Forensic Services: A UK-based forensic science company specializing in DNA analysis.
• Crimestoppers: An independent charity working with law enforcement to solve crimes through anonymous information provided by the public.
• Beast of Birkenhead: The moniker given to the unidentified perpetrator of Diane Synindal’s murder.

The Diane Synindal Case: A Decades-Long Investigation

The case centers around the brutal 1986 murder of 21-year-old Diane Synindal in Murzyside, UK. Synindal was attacked and killed after running out of petrol on her way home from a late shift at a local pub, driving a blue Fiat. The attack involved rape and severe physical violence, with her body discovered in an alleyway. The case has been marked by a significant miscarriage of justice and ongoing investigation.

The Wrongful Conviction of Peter Sullivan

For decades, Peter Sullivan was believed to be Diane Synindal’s killer and was convicted based on evidence available at the time. However, in the previous year, Sullivan was released from prison after 38 years of incarceration. This release followed new DNA testing conducted on samples originally collected from the crime scene. This makes Sullivan’s case the longest running miscarriage of justice recorded in UK history.

Advancements in Forensic Technology & New DNA Profile

The key to Sullivan’s release and the reopening of the investigation lies in advancements in forensic science. Specifically, collaboration with Cellmark Forensic Services allowed for the identification of a DNA profile from a sample recovered from Diane Synindal at the crime scene in 1986. This profile was not obtainable with the technology available at the time of the initial investigation. The speaker notes that forensic work has continually developed “year and year,” making this re-analysis possible.

Current Investigation & Reward

Currently, Merseyside police are actively seeking Diane Synindal’s true killer. Crimestoppers is offering a reward of £20,000 for information leading to the identification and apprehension of the perpetrator. The investigation hinges on the hope that someone possesses information about the events of that night and will come forward, now that a new DNA profile exists.

Unanswered Questions & Focus of the Investigation

The central question remains: is Diane Synindal’s killer still alive? The investigation is focused on determining if anyone has knowledge of the events surrounding her murder, particularly in light of the newly identified DNA profile. The case highlights the potential for forensic science to overturn wrongful convictions and the enduring pursuit of justice, even decades after a crime has been committed.
