Not a week goes by that Netflix doesn't release a gripping new true crime documentary, and this is no different.
The Sons of Sam: A Descent Into Darkness will delve into the infamous 'Son of Sam' serial killer, who murdered six people and wounded a number of others in a series of attacks in New York City between 1976 and 1977.
David Berkowitz was responsible for the murders, infamously sending a series of letters to the police gloating about them.

At the time, he claimed he was acting on the orders of his dog Sam, who was, in fact, a demon.
Despite these claims, though, Berkowitz later admitted this wasn't true and there was no demon hiding in his dog.
Using information reported by journalist Maury Terry, who published books on Berkowitz, the series will try to uncover whether or not he acted alone.
Berkowitz randomly murdered half a dozen people between 29 July 1976 and 31 July 1977, shooting them with his .44 revolver.

The first of his victims were teenagers Donna Lauria and Jody Valenti, a pair of friends who were in their cars in Pelham Bay when they were attacked.
His killing spree left New York and its inhabitants in a state of constant fear, but it wasn't until almost a year later that Berkowitz became known as the 'Son of Sam'.
The moniker followed his murder of Alexander Esau and Valentina Suriani, at the scene of which he left a note for the police.
It read: "I am deeply hurt by your calling me a wemon [sic] hater. I am not. But I am a monster. I am the 'Son of Sam'.

"Sam loves to drink blood. 'Go out and kill' commands father Sam."
In 1977, over a year after his first murder, a witness came forward with information that would help lead police to Berkowitz.
The witness reported having seen a man carrying what looked like a 'dark object' while out on the street.

On 10 August, after the witness reported seeing his car to the police, officers found his yellow Ford Galaxy in Yonkers, and Berkowitz was taken in for questioning.
Asking him who he was, Berkowitz reportedly replied: "I'm Sam."
"You're Sam? Sam who?" the officers asked.
To which he replied: "Sam. David Berkowitz."

Following his conviction, Berkowitz was sentence to 25 years-to-life for each of the six killings, and he remains in prison today.
The Sons of Sam: A Descent Into Darkness lands on Netflix on 5 May.
