Answer
There are a lot of people that believe Berkowitz did not and could not have pulled off all these murders by himself. And Berkowitz himself says that he did not act alone but was in fact part of a devil worship cult. But as far as I know he has never named names. If he was part of a conspiracy he has nothing to loose at this point by naming any co-conspirators and as a 'born again Christian' you would think he would feel some obligation to 'spill the beans' .
There has been talk that his neighbor's two sons (Sam Carr the owner of the infamous dog) were with Berkowitz in this Satanic cult and were part of the murders. I have no idea if there is any evidence to back that up and until there is it will remain just talk.
Answer
David Berkowitz would love that you believe in a conspiracy, anything to keep the spotlight on himself. Among other things, Berkowitz is a narcissist, you can see it in his letters. When he speaks of "the cult", he is too vague, too non-specific for someone who knew and worked with these "other people". But if you look at his life style, his personality and habits prior to and during his spree, you can clearly see what a loner he was and how minute the possibility that he could work with others, much less "coordinate an operation". He may have seen the teens that met at the site of the ruin where the satanic symbols were painted on the walls; he may have even had an occasion to speak with one or more of them, but no more than that. His personality did not allow him to interact with others to a greater degree than that.
On a recent network TV program, they said that the furniture in his room had been cleared out the day or day after he was arrested. This is not the case. Many years ago I saw police photos of the room taken right after his arrest. It's true that there was next to nothing in it, but there was the place on the floor where he slept, a table and a bunch of misc. other stuff. You could clearly see in these pictures that this room had not been "cleared out" but that this was how Berkowitz lived. You would be very hard put to find any person who had ever been in this room but Berkowitz before the police went into it. You have to see enough TV reports or read a number of books on a case before you get all the bits and pieces. I don't normally form an opinion from watching or reading just one.
