On 6 June 1991, 43-year-old Penny Bell was found murdered inside her car at the Gurnell Leisure Centre car park in Greenford, west London. She had suffered numerous stab wounds, and despite an extensive police investigation, her killer has never been identified. The case became one of Britain's best-known unsolved murders and was featured on Crimewatch.
Penny had left her home in Denham, Buckinghamshire, that morning and was believed to have arranged an appointment, but investigators were never able to establish conclusively who she intended to meet. This has remained one of the central mysteries of the case.
Over the years police have investigated numerous leads and appealed for information, but nobody has been convicted of Penny's murder. More than three decades later, the question of who she met that morning and why she was killed remains unanswered.
Cases like this show why even small pieces of information can become important years later. Do you think Penny knew the person who killed her, and could advances in forensic technology eventually provide the breakthrough investigators need?
