After 26-year-old Nicki Collingbourne evicted her half-sister, 52-year-old Yvonne Caylor, from her flat, the pair's already tumultuous relationship worsened. Just seven months later, Nicki was found dead in her home.
Caylor was swiftly taken into custody, but detectives were left baffled at the revelation of an apparent mystery man spotted in the vicinity by CCTV cameras wearing a high-vis jacket and glasses.
