Why Was Maury Terry Convinced Berkowitz Didn't Act Alone?
After being captured by police in 1977, Berkowitz confessed to the shootings and pleaded guilty, later being handed down six life sentences (which he is still serving today). Berkowitz would later tell police that it was his neighbour Sam Carr's "possessed dog" that ordered him to commit the crimes, however, Terry wasn't convinced he acted alone.
Despite Berkowitz not matching the "tall and blonde" description the Son of Sam survivors provided police, it was Terry uncovering John and Michael Carr, who were quite literally sons of Sam, that had him convinced the killings weren't done by a single person. The brothers were the sons of Sam Carr, Berkowitz's neighbour.
In fact, in one interview conducted between Terry and Berkowitz, he alleged the brothers were his accomplices—although, it's important to note they were never formally under police investigation.
After creating the docuseries, Zeman spoke out about what he believes really happened.
“There’s a preponderance of evidence to suggest that Berkowitz didn’t act alone,” he said, per The Wrap. “I have been told the names of those individuals, some of whom are still alive. So, you know, that remains to be seen… I think that I think there’s obviously enough doubt to suggest that it’s worth looking into."
Who Were John And Michael Carr, And What Happened To Them?
Besides the brothers being literally sons of Sam, the sons of Berkowitz's neighbour, Sam Carr, Terry spent decades trying to link the pair to the crimes that took place in New York City in the '70s.
Although their connection to the case would become difficult to prove, with both brothers passing away in the years following Berkowitz’s arrest in 1977—which many believe to be under suspicious circumstances.
John Carr was shot in the head in North Dakota in 1978, with his death sparking a conspiracy theory that'd he'd died after learning police were investigating his possible connection to the case. Although, that theory has never been proved.
Interestingly, following John's death investigators would discover he had been writing the son of Sam symbol—which the killer had taunted police with following the killings—on telephone books.
Michael Carr similarly died in mysterious circumstances in 1979 in a car accident in Manhattan, two years after Berkowitz confessed to the crimes and the same year police allegedly began looking at potential connections between the Carrs and Berkowitz.
