The Green Bicycle Case was a murder investigation and trial over the shooting of a young woman named Bella Wright in Little Stretton, near Leicester, England on 5 July 1919. Wright was killed by a bullet wound to the head. Earlier that evening she had been seen with a man on a green bicycle. Ronald Vivian Light was tried for her death but acquitted.
Ronald Light, 34 years old at the time, was a World War I veteran who had returned from the war with shell shock. He did not voluntarily come forth in response to wanted posters for the man on the green bicycle who had been riding with Wright on the evening she was killed, and he made an attempt to dispose of the bicycle. Once arrested he admitted to being with her shortly before her death, but denied killing her. He was successfully defended in court by Sir Edward Marshall-Hall KC.
How on earth was Light ever cleared of this murder? He was the only person seen with the victim shortly before their death, he had tried to dispose of the bicycle, and admitted to owning the gun holster which was found in the canal (along with bullets matching the one which killed the victim), and yet they were able to get him off on some technicality about ballistics and because he was calm and well-spoken in the witness box?
