MANAGUA, Nicaragua -- Alexis Arguello, who fought in one of boxing's most classic brawls and reigned supreme at 130 pounds, was found dead at his home early Wednesday.

Coroners were conducting an autopsy to determine the cause of death. Sandanista Party's Radio Ya and other local media were reporting it appeared to be a suicide. The La Prensa newspaper reported that Arguello -- elected mayor of Nicaragua's capital last year -- was found with a gunshot wound to the chest.

The 57-year-old Arguello retired in 1995 with a record of 82-8 and 65 knockouts and was a champion in three weight divisions. He was perhaps best known for two thrilling battles with Aaron Pryor and fights with Ray Mancini, Bobby Chacon and Ruben Olivares.
