The Ultimate Evil: An Investigation into America’s Most Dangerous Satanic Cult – Maury Terry
David Berkowitz, the Son of Sam, was a lunatic who shot and killed a bunch of innocent people. When he was arrested, he admitted to all of the killings. After the arrest, a reporter named Maury Terry started researching the murders and became convinced that David Berkowitz was actually involved with a Satanic cult and that he did not commit the murders alone.
While on his killing spree, the killer (at least one of them) sent letters to the police and the press referring to himself as “the son of Sam”. Berkowitz later claimed that Sam was an ancient demon that had possessed his neighbour’s dog. The neighbour’s name was Sam Carr. Terry became convinced that Sam Carr’s actual sons had been Berkowitz’s accomplices.
I’m no expert on this case, but that idea doesn’t seem absolutely unfeasible to me. Berkowitz was well known to the Carr family, and both sons died unnatural deaths shortly after Berkowitz was arrested. Some people who know lots about the case also believe that Berkowitz did not act alone, and it seems impossible to prove that the Carr brothers were not involved.
I knew that the claims in The Ultimate Evil were controversial before I read it, and I went in assuming that most of it was complete bullshit. I knew that there was a Netlix documentary series about it, and I thought that this series was going to be an exposé on how Terry’s ideas were all nonsense. There’s some stuff in the book (Terry’s decoding of the Son of Sam letters and the Roy Radin stuff) that seemed like utter nonsense as I was reading them, but some of it was actually quite convincing. When I watched the Netflix documentary, I expected it to provide refutations of these ideas, but it doesn’t.
Berkowitz started off claiming he acted alone, but he changed his story after spending a bit of time in prison. To this day he claims that he had accomplices. He doesn’t seem like a particularly reliable person though. He clearly enjoys attention, and the Satanic cult claims were probably the most efficient source of attention for an incarcerated murderer in the early 1980s. Both the book and the Netflix documentary series make it seem like Berkowitz was merely telling Terry exactly what he wanted to hear. This muddies the water, but it doesn’t actually discredit all of Terry’s evidence.
Much of what Terry says is clearly conjecture, but I don’t think the idea that Berkowitz had accomplices should be immediately disregarded. Those Carr brothers were definitely weirdoes. Both were scientologists, and one supposedly had a thing for murdering animals.
The Netflix documentary alludes to the fact that this book fed into the Satanic Panic of the 1980s, and it features clips of Maury Terry being interviewed alongside my old friend Phil Phillips. I wanted to be able to write-off Terry’s theory about the role of Satanism in the murders, but if you look at the letters, the killer(s) clearly had some interest in occultism. I don’t buy any of the “large, organised network of powerful Satanists” nonsense or any of the crap about the links between the Son of Sam and Charles Manson, but Berkowitz did seem to have some connections to occultism. Nevertheless, Terry’s efforts to bring attention to his work by jumping on the Satanic Panic bandwagon seem to have backfired. There’s a couple of parts where he mistakes Iron Maiden lyrics written on walls for Satanic prayers. When he’s trying to decode the letters he does the old “reading it backwards” trick, and at one point he even references James Blish’s Black Easter. So much of this book is dumb that he interesting parts seemed pretty uninteresting.
One of the main reasons I wanted to read this book was because I had read it contained information on the elusive Four Pi cult, an evil group of weirdos led by “The Great Chingon” that I previously came across in Ed Sanders’ The Family and Gavin Baddeley’s Lucifer Rising. The only information in here that Terry adds is that the group split up at the end of the 60s because some members were too horny. Rereading the passage in question, I realised that Terry’s source was actually Peter Haining’s The Anatomy of Witchcraft, a book which David Berkowitz annotated and sent to the Ward County Sheriff’s Department when they were investigating John Carr’s death. (Needless to say, I have already started reading that book for a future post!)

I actually read the revised edition of The Ultimate Evil. It has a little bit extra on Roy Radin’s death and a few other things. Both editions of this book are extremely long, extremely detailed and ultimately extremely boring. The Netflix documentary is a much clearer way to understand Terry’s ideas. There’s really no need for anyone to slog through this unenjoyable mess (that does, admittedly, make a few good points.)
