Bella Wright, a 22-year-old factory worker, was shot in the head the same day as she was seen with a man on a green bicycle.
Ronald Vivian Light, a World War I veteran, was tried for her murder and later acquitted.
During the trial, two young girls testified that Light had chased them on their bicycles the day of Wright's death, and he had previously admitted to two cases of improper conduct with minors.
Light said he had simply helped Wright find a spanner for her bike, and that the blood found near her body was from a crow. On the advice of his lawyer, Light admitted to everything he was accused of except Wright's murder.
However, Light did hide his bike for five months after Wright's death, and he later dismantled it and threw it into a river.
Books have been written about the case, and one claims that Light confessed the crime to a police officer. However, this is unproved.
