Two men have been cleared of murder in relation to the death of former three-weight boxing world champion Hector Camacho.
The Puerto Rican passed away in hospital after being shot in the face during a gun attack in Bayamon last November.
Camacho was in his car with his friend Adrian Mojica when the incident occurred, with the other man dying at the scene.
Forensic evidence has now proven that two men arrested on suspicion of killing Camacho were not responsible for his death, Reuters reports.
Camacho was one of Puerto Rico's most successful boxers, winning 79 of his 88 fights, including a knockout victory against Sugar Ray Leonard.
