Greater Manchester Police are offering a £50,000 reward to identify the killer of 14-year-old Lisa Hession, who was sexually assaulted and strangled in 1984. Lisa’s body was discovered near her home shortly after she went missing while walking home from a party. Despite advances in forensic techniques, no one has been charged in the case. The head of the cold case unit emphasizes the importance of public information in solving this decades-old crime, which remains unsolved.
