Hector 'Macho' Camacho, 50, died four days after he was shot while sitting in a parked car in San Juan. He was declared brain dead on Thursday. Police are still investigating the incident, which also claimed the life of a friend of Camacho’s.

Camacho was a world champion in three weight classes: super featherweight, lightweight and junior welterweight. Among Camacho’s biggest wins were victories over Edwin Rosario for the WBC lightweight championship in 1986 and Ray Mancini for the WBO junior welterweight championship in 1989. Camacho also defeated Roberto Duran and Sugar Ray Leonard near the end of their respective boxing careers. He lost title fights to Julio César Chávez in 1991, Félix Trinidad in 1994 and Oscar De La Hoya in 1997. He finished with a career record of 79-6-3.
