Dr. Torres says Camacho went into cardiac arrest in the pre-dawn hours Saturday. He was then taken off life support and died shortly thereafter.
Camacho was declared brain dead on Thursday following a shooting in his hometown of Bayamon.
The former world champion was 50.
Family and friends of Hector “Macho” Camacho had held vigil Friday. His mother said she would decide to pull the clinically brain dead former boxing champion off life support once the rest of his sons arrive at the hospital in San Juan, Puerto Rico.
Doctors pronounced Camacho clinically brain dead Thursday after a shooting earlier in the week in his hometown of Bayamon. The family had been torn over whether to keep him on life support.
“I lost my son three days ago,” his mother, Maria Matias, said during a news conference. “He’s alive only because of a machine. My son is not alive. My son is only alive for the people who love him.”
Camacho, who won four world titles, one each in the featherweight and lightweight divisions and two in the welterweight class, has four sons from different relationships.
Camacho was shot in the face as he and a friend, Adrian Mojica Moreno, sat in a car parked outside a bar Tuesday night. Police spokesman Alex Diaz said officers found nine small bags of cocaine in Moreno’s pocket and another bag open inside the car. Moreno died in the attack.
