Hector "Macho" Camacho, the brash and charismatic boxer who once sat at the apex of his sport, was pronounced dead Saturday after doctors took him off life support at his family's direction. He was 50.

"He excited boxing fans around the world," promoter Don King said.

Camacho (76-6-3) fought for three decades, from his debut against David Brown in 1980 in New York to a forgettable swan song against Saul Duran in May 2010 in Kissimmee, Fla. He fought some of the biggest stars, including Sugar Ray Leonard, Oscar De La Hoya, Julio Cesar Chavez and Roberto Duran.

Camacho was ambushed in a parking lot in his Puerto Rican hometown of Bayamon on Tuesday night. He never regained consciousness and was declared brain dead Thursday.

Cocaine was found in the car in which he and Adrian Mojica Moreno were shot and killed. No arrests have been made.

"He revolutionized boxing," Chavez said.
