Doctors declared former Puerto Rican welterweight boxing champion Hector Camacho brain dead on Thursday.

Director of the Centro Medico trauma center in San Juan Dr. Ernesto Torres, who was treating the famed boxer, said: "We have done everything we could. "We have to tell the people of Puerto Rico and the entire world that Macho Camacho has died, he is brain dead."

Camacho's family members have diverse opinions on whether life support should be taken off him.

Camacho's father was in favor of life support to be taken off the boxer. "This is a very difficult moment," he said. But his mother and a sister were not ready just yet.

Camacho's oldest son will reach the hospital on Thursday night, and then the family will probably take a decision. "Let's remember him as a good man," Camacho's former manager and old friend Steve Tannenbaum said. "He was a good father, a good son."

Tannenbaum added he idolized Camacho as a boxer. "He is one of the greatest small fighters that I have ever seen," he said. "Hector Camacho had a legendary status.

"He was almost like the indestructible man. He had so many troubles with the law, so many altercations in his life. It's a great shame."

Three-time world boxing champion, Camacho, who was popular among fans by the nickname "Macho," was sitting in a Ford Mustang with a friend outside a bar, when two gunmen opened fire on them on Tuesday night.

As per Police spokesman Alex Diaz, they found nine small bags of cocaine in the friend's pocket, and a 10th bag was open inside the car.

Torres said the bullet damaged three of four main arteries in Camacho's neck and it affected blood flow through to his brain.

"That lack of oxygen greatly damaged Macho Camacho's brain," he added.

Torres had claimed late Wednesday that Camacho was still showing irregular and intermittent brain activity.

Camacho won the super lightweight, lightweight and junior welterweight world titles in the 1980s. He has a career record of 79-6-3.
