Dog shootings and mysterious letters initially put Berkowitz on Intervallo s radar.
On Christmas Eve 1976, Intervallo and Chamberlain were called to probe the shooting of a German Shepherd. By that point, Berkowitz had already shot six people in three separate incidents in the Bronx and Queens, killing one, Donna Lauria. She was 18.
Four months later, the Yonkers cops investigated the shooting of a black Labrador retriever hit by a .22 caliber bullet in the dog s backyard. The Labrador was owned by Sam Carr, the apparent Sam in Son of Sam. Both dog shootings occurred close to Berkowitz s home.
After searching the area, Intervallo and Chamberlain determined the only window that had a direct line to Carr s Warburton Avenue backyard was Berkowitz s apartment 7E.
Ok, we need to talk about The Sons of Sam true crime series on Netflix. At first, it covers what looks like a pretty closed case about serial killer David Berkowitz. But then it dives head first into the huge investigation by journalist Maury Terry, and now a lot of people have been left wondering why John Carr was never properly investigated in the case.
In the summer of 1976, a serial killer was on the loose in New York. Over a year after his first crime, David Berkowitz would be found to be the man who killed six people and wounded seven others. But, investigator and journalist Maury Terry didn’t think he acted alone. Evidence pointed towards a murderous cult – but nobody else was ever convicted in the case.
The latest true crime docuseries on Netflix is The Sons of Sam: A Descent Into Darkness, all about the crimes of serial killer David Berkowitz and journalist Maury Terry’s investigation into the theory Berkowitz didn’t act alone. One of the main parts of the investigation focused around a series of letters which were sent to police and the media, which were signed as being from The Sons of Sam killer.
During the time of the murders, the killer sent a number of letters to the NYPD and local New York media. These taunted the recipients and said he would continue committing his awful crimes. None of the letters are read in full during the Netflix series, and only some show on screen for a few seconds. So, here’s what all The Sons of Sam letters actually said.
