Hit and Run of Mary Doherty

On December 23, 1922, in Blackpool, England a vehicle would run over 66-year-old Mary Doherty killing her. The vehicle would then drive off and the driver would never come forward. It was unbelievable that the killer did not know that they had run over Mary. A search for the vehicle was said to have happened all over Lancashire and Yorkshire, but the driver was never found.
