MEXICO CITY (AP) -- U.S. prison authorities say a Mexican man convicted in the 1985 torture-slaying of DEA agent Enrique Camarena has died at a federal correctional facility in Florida.
Ruben Zuno Arce was serving a life sentence for conspiracy and kidnapping.
Zuno Arce's 1992 conviction drew attention partly because he was a brother-in-law of former Mexican President Luis Echeverria, who governed from 1970 to 1976.
U.S. Bureau of Prisons spokesman Chris Burke said Wednesday that Zuno Arce died Tuesday but did not specify the cause of death.
He said Zuno Arce was 82.
Camarena was kidnapped and killed in western Mexico by drug lords in retaliation for anti-drug raids.
His death sparked a large-scale investigation that toppled some of Mexico's top capos and included allegations that members of Mexico's political elite were involved.
