The two groups were vying to control the drug trade within Pascoal Ramos penitentiary in Cuiaba, 980 miles northwest of Rio de Janeiro, said Jose Carlos de Carvalho, coordinator of the Mato Grosso State prison system. Hundreds of riot troops were sent in to end the violence. Carvalho insisted no police were involved in the killings. In a search police said they found two revolvers and 350 packets of cocaine. - --- MAP posted-by: Keith Brilhart
