SAN JUAN — The family of Hector ‘‘Macho’’ Camacho tried to decide Wednesday whether he should be removed from life support after a shooting in his Puerto Rican hometown left the former boxing champion clinging to life and his fans mourning the loss of a dynamic and often troubled athlete.

Doctors at the Centro Medico trauma center in San Juan found that Camacho had irregular and intermittent brain activity late Wednesday, said Dr. Ernesto Torres, the center’s director.
