Dr William Gerald was the surgeon at Weatherfield General who attended both Katy and Tommy Harris after their treatment at the hands of brothers Andy and Nick Morgan in April 2003. The previous year a third Morgan brother Tom, had been convicted of murder when he shot a man in a Sheffield pub where Angela Harris was a barmaid. She gave evidence against the notorious family and the Harrises were put on a witness protection programme and moved to Weatherfield under the assumed name of "Nelson". The Morgan brothers tracked the family down, armed with a gun, kept Katy hostage in No.6 where she was prevented from taking her insulin by Nick and went into a diabetic coma.
