Eddie Guerrero [SEP] Introduction
Eduardo Gory Guerrero Llanes (October 9, 1967 – November 13, 2005) was an American professional wrestler. He was a prominent member of the Guerrero wrestling family, being the son of first-generation wrestler Gory Guerrero. Guerrero performed in Mexico and Japan for several major professional wrestling promotions, and in the United States performed for Extreme Championship Wrestling (ECW), World Championship Wrestling (WCW), and most notably World Wrestling Federation/Entertainment (WWF/WWE). Guerrero's gimmick was that of "Latino Heat", a crafty, resourceful wrestler who would do anything to win a match. His catchphrase became "I Lie! I Cheat! I Steal!" and was used in one of his entrance themes; he partly used this phrase in the title of his 2005 autobiography, "Cheating Death, Stealing Life".
