Police are appeal for fresh information to help solve the murder of Debbie Linsley.
She was stabbed to death on a train travelling from Orpington to London Victoria in 1988.
Twenty five years on from the murder of Debbie Linsley, an innocent woman on a train in broad daylight, we are still hopeful that the murderer can be caught.
The passage of time has not diminished the shocking nature of this crime; it has just made it harder to bear for her loved ones, when justice has not been achieved.
We still believe there are people out there with information that could be vital to a breakthrough in the case.
I would urge those people to call us. I can assure them that they will be dealt with sensitively
