1983: Peter Alan Fell, charged with double murder and sentenced to life for the 1982 stabbing of two women dog walkers on Aldershot Common, after he made a series on anonymous telephone calls to the police. But despite spending 12 years in prison, it seems Fell was just an attention-seeker, as he does not match the original descriptions given by witnesses.

1989: Gary Mills and Tony Poole, sentenced to life for murder, after a fight between a group of criminals in a flat in Gloucester resulted in the later death of Hensley Hendrix 'Willy' Wiltshire. Mills claimed he acted in self defence, Poole denied being involved at all. This investigation finds all of the witnesses appear to be unreliable, and that the victim need not even have died.
