The man convicted of the crimes committed by the Boston Strangler is/was named Albert DeSalvo. I do know a number of years ago (in the 80's), he was housed at Walpole prison , about 20 miles outside Boston (I believe the prison is now known as "Cedar Junction" or something like that). At that time there was an observer program where several citizens spent the day observing at the prison. I knew someone who was an observer and they told me that DeSalvo was there and that they had a conversation or two with him.
