Answer:
The sadistic psycho referred to as the ".44 Caliber Killer" and "Son of Sam" is David Berkowitz.
Step-by-step explanation:
David Berkowitz, also known as the "Son of Sam," terrorized New York City in the mid-1970s. From 1976 to 1977, Berkowitz targeted couples parked in cars, predominantly in the Bronx. His weapon of choice was a .44 caliber revolver, which earned him the moniker The .44 Caliber Killer.
Berkowitz's crime spree instilled fear in the city, and his taunting letters to the media and law enforcement added to the hysteria. Eventually, he was apprehended in August 1977. Berkowitz later claimed that he was influenced by demonic forces, and he is currently serving a life sentence for the series of murders.
