John Riccardi was, and maybe still is, a man of some intrigue. He made millions of dollars pulling off international heists as a cat burglar and lived high on the hog as they say, enjoying fine wines, designer clothes, and expensive cars. Then something in his brain went haywire. He began tormenting a woman named Connie Navarro whom he'd had a brief relationship with. He would not leave her alone. Day and night. He'd break into her house, he'd watch her in public. It ended badly, as you'd imagine. William Noguera knew John Riccardi well, as they served time together on San Quentin's Death Row, and he breaks down the mind of one John Riccardi.
