On the afternoon of 23 March 1988, Deborah Linsley was murdered on a train between Petts Wood and London Victoria stations in Greater London. Although there were about 70 people on the train, and Linsley apparently fought and injured her attacker, only one passenger reported hearing anything suspicious. The killer has not been identified. Stored blood evidence from the scene allowed the case to be re-examined a decade later using DNA technology, and in 2002 it was re-opened with a major publicity campaign. A police reward is on offer.
