Did I correctly remember the hanging as written in Capote's book?

Rating: Null/10 (1 November 2008)

It has been many years since I read "In Cold Blood" but one incident in it was Capote's depiction of the hanging. In the film the execution is conducted on a scaffold. As I remember the book there was no scaffold and these murderers were hanged from pipes in the basement of the prison. Any input on this would be appreciated. Another interesting incident in one of the recent movies on this story that always baffled me was why the authorities allowed Capote complete access to a men on death row. Capote never wrote of this in his book apparently because one movie had a prison official accepting money allowing such access which would seem to be a felony if revealed at the time. By the time the movies were released the statute of limitations applied and thus rendered this issue moot.
