Kirsty Williams is a member of the Williams family who targeted the Patrick family in 1998. Gina Patrick had witnessed a stabbing committed by Kirsty and ended up being called to testify in her trial. The Williamses targeted Gina's family, who had recently moved into 1 Stockton Lane with Jill Patrick's new partner Jack. The flat was targeted by the Williamses and Gina's sister Kate was threatened with an acid attack, so Gina decided not to testify. However, Gina was arrested for failing to appear in court and ended up giving evidence in February 1998.
