( CNN ) -- His nickname is `` The Fever . '' Mexican officials say Jose Carlos Moreno Flores was a major drug lord in charge of trafficking and operations for a large Mexican cartel in the coastal state of Guerrero , where the beach resort of Acapulco is located . According to Mexico 's Ministry of Defense , Moreno Flores was caught Sunday in Mexico City 's Tlalpan District . His capture is particularly important because Moreno is allegedly tied to the Sinaloa Cartel led by Joaquin `` El Chapo '' ( Shorty ) Guzman , Mexico 's most wanted man . Guzman , who remains a fugitive , commands such a vast international drug trafficking network and his profits from the illicit trade are so big that he made Forbes Magazine 's list of the world 's most powerful . He appeared at number 60 on last year 's list with an estimated fortune of $ 1 billion . The magazine calls him `` the biggest drug lord ever . '' The U.S. Drug Enforcement Administration is offering a $ 5 million reward for information leading to the capture of Guzman . Mexico 's top drug kingpin lord , who 's reportedly 54 , was captured in Guatemala in 1993 , but escaped eight years later . Officials say Moreno Flores , who was considered one of Guzman 's lieutenants , did business with drug traffickers from Costa Rica and Guatemala from his base of operations in Chilpancingo , capital of the state of Guerrero . From Chilpancingo , Moreno Flores shipped the drugs ( mainly cocaine ) to the United States by land . `` The Fever '' was also allegedly in charge of the cultivation , harvesting and distribution of marijuana in the fertile mountain region of Guerrero state . Violence in Chilpancingo had recently increased because a group of Sinaloa Cartel operatives led by Moreno Flores have been fighting a turf war with a rival group known as `` Los Rojos '' ( The Red Ones ) . When he was caught , Moreno Flores was in possession of three high-caliber weapons , communication equipment and one unspecified vehicle .
