Well, to make a long story short, David Berkowitz is not Jewish! he was born Jewish, but he later on converted to Christianity, which makes him not Jewish.
Since David Berkowitz's mother is Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes him Jewish (though once again, he was later on converted to Christianity, which makes him not Jewish after all). His father is Jewish too.
David Berkowitz (whose full birth name is Richard David Falco) was born on June 1, 1953 in Brooklyn, New York, US.
He is known as the Son of Sam and the .44 Caliber Killer, an American serial killer convicted of a series of shooting attacks that began in the summer of 1976. Perpetrated with a .44 caliber Bulldog revolver, the shootings continued for over a year, leaving six victims dead and seven others wounded.
