According to Laura Foreman's Serial Killers, Dennis almost immediately confessed to the crimes after being arrested, telling officers: "It's a long story; it goes back a long time. I'll tell you everything. I want to get it off my chest. Not here — at the police station." When he was asked if anyone else lived at his flat, he added: "Fifteen or sixteen, since 1978." Speaking about why he killed so many people, he reportedly said: "I wished I could stop, but I couldn't. I had no other thrill or happiness."
