Becky Swain was the wife of Lisa Swain who died sometime in 2021 after being hit by a car whilst on duty. Following an interview with Lisa and her collegue DC Kit Green over the break-in at Underworld and a brutal attack on Carla Connor within the premises in November 2024, suspect Matty Radcliffe mentioned Becky's name upon his release, leading Lisa to believe that he knew something about Becky's death.
