Tijuana, Mexico: Former world champion boxer Juan Jose Estrada was stabbed to death over the weekend in what was believed to be a family quarrel in the Mexican border city of Tijuana, authorities said Monday.
Estrada, nicknamed "Dinamita," won the WBC International world championship in the super bantamweight division in 1987, and the WBA title in 1988.
Sources close to the investigation said Estrada was taken to a pharmacy early Sunday with a stab wound, but died before an ambulance arrived to take him to the hospital.
"It's said he had a quarrel at home with some relatives and that led to one of them wounding him, apparently with a knife," an official in charge of the investigation told AFP.
Jose Manuel Yepiz, a spokesman for the prosecutor's office, said no arrests have been made in the case. After retiring from boxing, Estrada ran into trouble with the law, and was jailed in 2005 on a drug charge. At the time of his death, he made a living as garbage collector.
