Captain Joseph Borrelli of the New York City Police Department was one of the key members of the Omega Group. Operation Omega was the task force headed by Deputy Inspector Timothy Dowd to find the psycho who was killing women in various parts of the city with a .44 caliber handgun.
The ".44 Caliber Killer" was getting a great deal of press and Borrelli's name had appeared frequently. Now on April 17, 1977, he was looking at a letter addressed to him that had been left at the scene of the latest in this series of murders: With misspellings, it read:
Dear Captain Joseph Borrelli,
I am deeply hurt by your calling me a wemon hater. I am not. But I am a monster. I am the 'Son of Sam.' I am a little brat.
When father Sam gets drunk he gets mean. He beats his family. Sometimes he ties me up to the back of the house. Other times he locks me in the garage. Sam loves to drink blood.
'Go out and kill,' commands father Sam.
