Hector "Macho" Camacho was a brash fighter with a mean jab and an aggressive style, launching himself furiously against some of the biggest names in boxing. And his bad-boy persona was not entirely an act, with a history of legal scrapes that began in his teens and continued throughout his life. The man who once starred at the pinnacle of boxing, winning several world titles, died Saturday back in the Puerto Rican town of Bayamon where he was born, ambushed in a parking lot in a car where packets of cocaine were found.
