Yonkers, 1976. Above the Hudson sits the ruin of what was once the grandest garden estate in America, its terraces gone feral, its old stone gatehouse renamed the Devil's Cave by local teenagers. And through 1976 and into 1977, people walking the trails keep finding dead German shepherds. Nobody calls it a case, because it isn't one. A year later, a man from this same neighborhood confesses to eight shootings and blames a demon that lived in a dog. The city files that under madness and moves on. But the park is still there. So are the questions.
This is Part 3 of our three-part Summer of Sam series, the finale, and it's everything that refused to stay closed after the guilty plea.
Kathryn and Gabriel are upfront about what this episode is: some of it is documented record, and some of it rests on the word of one convicted, self-admitted liar and the lifelong work of one investigator. We hold both against the light and tell you exactly where the documentation stops.
We start with the recant. Two years into his sentence, after surviving a throat-slashing in prison he refused to explain, David Berkowitz told the psychiatrist who examined him that the demon-dog story was an invention, built for an insanity defense he never used. He knew what he was doing. He did it anyway. That recant kills the demon, but it also proves, from his own mouth, that this man can lie convincingly for years, which stamps a warning on every word he says afterward, including everything still to come. We follow his 1987 conversion, his "Son of Hope" rebrand, and his decades of mostly declining to seek his own parole.
Then the reporter. Maury Terry, a corporate writer who couldn't accept an answer with a hole in it, spent his life on the anomalies: police sketches that never matched each other or Berkowitz, a small yellow car at the final scene that was never his, timelines he couldn't make work for a single shooter. We're honest that anomaly-hunting on a huge case always yields loose ends, and also that Terry wasn't a lone crank, the Queens DA formally reopened his files in 1979 and publicly doubted the lone-gunman finding, though nothing was ever charged. Terry's 1987 book advanced a stark claim: not a man, but a network, an occult circle operating out of Yonkers with Berkowitz as one hand among several.
We walk that chain link by link and mark every weak one. The Carr family, whose son John's real childhood nickname, "Wheaties," appeared in a Son of Sam letter a year before anyone connected the killer to that family, and who, with his brother Michael, died within twenty-six months of the arrest, one a ruled suicide, one a ruled car accident, neither ever questioned. We are explicit that these are dead men, never charged, and that the theory naming them as shooters comes largely from Berkowitz. We cover the park, the aqueduct trail, the dead dogs, and the real but never-charged Process Church at the far end of Terry's chain. And we stage the honest reckoning: in the 1990s prison tapes, Berkowitz assigned triggers only to people who were dead, sued, or otherwise unable to answer, and the single most checkable claim of the whole theory, that the network committed the 1974 Arlis Perry murder in California, collapsed in 2018 when DNA identified a lone Stanford security guard with no connection to any of it.
We end where a case like this has to: unresolved. A closed case you can build honestly, one man and one gun. An open one you can build too, on real ground with soft patches. What you cannot do, fifty years on, is force both into one clean story. And we give the last human word to the survivors, who never got a hearing to skip.
This concludes our three-part Summer of Sam series.

The documented public and legal record of the David Berkowitz case, including his conviction and the 1979 Attica assault; the interviews and correspondence in which Berkowitz recanted the "demon" account to psychiatrist David Abrahamsen, and Abrahamsen's published work; the 1979 reopening of the Queens District Attorney's files under John Santucci and his stated doubts about a lone gunman, which produced no charges; Maury Terry's investigation and his 1987 book The Ultimate Evil, cited here as the source of contested claims rather than of established fact; the documented deaths of John Carr (February 1978, Minot, North Dakota, ruled a suicide) and Michael Carr (October 1979, Manhattan, ruled an accident); public information on the Process Church of the Final Judgment, including its founding, its American presence, its dissolution, and the litigation over its portrayal in a book on the Manson case; the 1990s televised prison interviews between Terry and Berkowitz and the claims Berkowitz made in them; the handwritten margin notes Berkowitz mailed regarding the 1974 murder of Arlis Perry, and the Santa Clara County Sheriff's 2018 announcement that DNA identified Stephen Crawford, who died by suicide as a warrant was served; the 2021 documentary series built from Terry's archive and the 2025 series built from Berkowitz's prison audio; New York parole records, including the denials since 2002 and the skipped 2026 hearing; and public statements from survivors including Robert Violante, Carl Denaro, and Jody Valenti. Claims resting on a single source are attributed as such throughout.

Content warning: This episode discusses murder, a prison assault, suicide, animal cruelty, and occult themes, and it examines an unresolved theory about a series of killings.

David Berkowitz was convicted of and pleaded guilty to these crimes, and that conviction is not in dispute here. This episode also examines a decades-old theory that Berkowitz did not act alone. That theory is not established fact. It rests substantially on the claims of Maury Terry and on statements by Berkowitz himself, who confessed, then admitted fabricating his original account, and who is therefore, by his own conduct, an unreliable narrator; his later claims are presented as his claims and should be weighed accordingly. Where the episode discusses an alleged network or specific alleged participants, it presents allegations and interpretation, not proof, and the hosts reach no conclusion.
Several people named or described in this episode, including John Carr and Michael Carr, are deceased, were never charged with any crime connected to these killings, and are named here only because they figure in publicly reported claims and theories. Nothing in this episode asserts or should be taken to assert that either brother, or any member of the Carr family, or the Process Church of the Final Judgment, committed any crime; the Process Church was never charged with any offense, and the episode notes its successful legal action over a prior portrayal. The 2018 DNA resolution of the Arlis Perry case, identifying a single unconnected individual, is presented as the documented outcome it is. Deaths ruled suicides or accidents are described as officially ruled, and contested scene details are attributed to their sources. The victims, survivors, and their families are real people, several of them living, and are discussed with respect and without any intent to sensationalize their suffering or intrude on their privacy. References to any person, living or deceased, are made in the context of public records and reporting and are not intended to defame, harass, or cause harm. Any third-party names and trademarks remain the property of their respective owners and are referenced under fair use for purposes of commentary, criticism, and reporting.
