Sam Carr liked to drink. Actually I don't know if he liked to drink or if he tied up dogs or beat his family. But Son of Sam left a letter at a crime scene with such a complaint. The author was a German Shepard and he barked a lot at David Berkowitz who liked to mind his own business with a .44 calliber handgun. David didn't like dogs. They had too much to say to him.

Dogs have no thumbs so they can't write letters to Jimmy Breslin at the New York Daily News. Berkowitz had to hold the pen in composition. Arf, arf, arf, arf. "Sometimes he ties me up to the back." Arf, arf, arf, arf. "I'll be back. I'll be back."

Son of Sam wrote a letter to Jack Cassara in which he pretended he was Sam and Francis Carr in Yonkers. Jack looked up Sam and called him. They met under these strange circumstances and conversation turned to dogs. Stephen Cassara remembered how a certain David Berkowitz hated the family dog. Funny, the Carrs had a neighbor named David Berkowitz who hated the family dog. They left convinced Berkowitz was a nutter. They thought he was Son of Sam.

It took a while to convince police that Berkowitz was their man. But when officers in Yonkers researched the matter further, the found a perfect profile match. Son of Sam liked to kill people with guns, David Berkowitz liked to kill people with guns... Police moved in and made the arrest:

"Now that I've got you," the detective said, "who have I got?"
"You know," David replied
"No, I don't. You tell me." he countered.
Smiling, he responded, "I'm Sam. David Berkowitz."

Arf, arf, arf, arf. "Sometimes he ties me up to the back." Arf, arf, arf, arf. "I'll be back. I'll be back."

David Berkowitz never terrorized the streets of London. Had he done so, this idea would have been quickly, nipped in the bud.
