- Albert DeSalvo: [inside sanitarium] But... I don't belong here.... I-I guess everybody says that, don't they?

- Title card: [opening title card] This is the story of 'Albert DeSalvo', the self-confessed Boston Strangler. The characters and incidents you are about to see are based on fact.

- Sgt. Frank McAfee: What are you trying to tell us, that it was a doctor or an Eagle Scout?
- John Asgeirsson: What about the sex? What did he actually do to them?

- Albert DeSalvo: What did you tell the children where I am?
- Irmgard De Salvo: They haven't asked.
- Albert DeSalvo: What... What do you mean, "they haven't asked"?
- Irmgard De Salvo: Well, they're only... they're only little children.
- Irmgard De Salvo: I know, but... they accept things.

- John Asgeirsson: Come on, Captain, looks to me like a nut's loose.
- Sgt. Frank McAfee: Nuts don't ransack apartments.

- Julian Soshnick: How many have you scored with ?
- Lyonel Brumley: Around two thirds.
- Julian Soshnick: In six months !
- Sgt. Frank McAfee: Any idea why you do it ?
