An 80-year-old man who pleaded guilty to drug charges sold crack cocaine from his house and gave some of the drugs to prostitutes in exchange for sex, his lawyer said. Felix Cocco, of Pittsburgh, pleaded guilty Wednesday to charges of possession of a controlled substance, possession with intent to deliver and possession of drug paraphernalia. Police said Cocco had been dealing drugs for nearly a year when he was arrested in November. Officers seized crack cocaine, a digital scale and packaging materials, police said. Authorities said they caught Cocco dealing again in February. "I was trying to stay alive, your honor — pay my bills," Cocco told the Allegheny County judge.
