According to Maury Terry's New York Times bestseller The Ultimate Evil, it would have been virtually impossible for the two not to have been aquainted. They were part of the same nation-wide satanic cult known as the Process and have mutual friends and connections. Manson II, aka William Metzner, like Berkowitz before him, is spending time (in a California prison) for the cult related murder of Hollywood producer Roy Radin and a Hollywood prostitute named June Mincher.
Known as the Cotton Club murders, Mentzer and an accomplice named Alex Marti, were sentenced to death, meaning they will die by lethal injection in California's death chamber at San Quentin Prison, once the appeals process has run it's course. There were at least two others involved in the murder plot of Radin but only Mentzer and Marti recieved death sentences.
Manson II or David Berkowitz was convicted for the murders or a New York producer and a Madam. He was sentenced to life in Prison without any parole in 1991, in the state of California.
Manson II is the name given to an unknown person involved first with a Satanic cult known as the Process, and was involved with Charles Manson before and during the Tate-LaBianca murders, and second, responsible for crimes associated with this same cult on a nation-wide scale including, but not limited, to the Son of Sam murders in New York, with David Berkowitz as the 'scape goat'. After re-opening the S of S murder cases and further investigation the conclusion was that Berkowitz was responsible for only the killings in the Bronx area of NYC in 1976 to 1977 when he was finally arrested. Investigative reporter Maury Terry's decade long probe into the Son of Sam murders led him on a disturbing journey, begining in 1977 (the summer of Sam), to the west coast and the crimes of the Manson family, to the midwest where the Process has affiliates, to Texas and back again to NYC. Terry's book The Ultimate Evil is his wakeup call to Americans, delving into the underbelly of Satanic cults that have sprung up in the US, some gaining respectablity such as The Church of Scientology, which has it's founder, L. Ron Hubbard, a self-proclaimed Satanist.
The total can only be guessed at. William Metzner, incarcerated in a California prison for the murders of Hollywood producer Roy Radin and Hollywood prostitute June Mincher, may have killed others, and it seems likely that he has. Once thought by some to even be the serial killer named Zodiac, the California killer of the 1960's and 1970's, but has been all but eliminated as a suspect for those murders. Metzner, exposed as author Maury Terry's 'Charles Manson II', Mentzer's ties to a nation-wide satanic cult that involved many bizzare murders including the 'Son of Sam' murders by fellow cultist David Berkowitz. Terry's bestselling expose' of the alarming rise in satanic cult crimes involved an investigation that spanned a decade and involved David Berkowitz, many movers-and-shakers of the movie industry, Charles Manson, the music industry including Dennis Wilson of the Beach Boys and other big names in recording, and investigated for years by not only Terry but by other notables such as FBI special agent Ted Gunderson, an authority on crimes connected with cults. I believe other killings that may be connected to Manson II are being investigated quietly in the hope that some old cases can finally be closed and the extent of satanic cults can finally be revealed. Whether this will mean more prison time for Manson II is hard to determine at this point. We will have to wait and see what happens next. Mentzer is going nowhere, at least for now.
