"Cummins killed his victims during regular nighttime blackouts caused by The Blitz. He would do this by strangling them, but in the case of his second victim, Evelyn Oatley, he also slashed her throat post-mortem. His last three victims were also sexually mutilated with a variety of objects, such as a can opener, a razor blade, a knife, and a candlestick."
