Edelio López Falcón

Edelio López Falcón (1965 – 6 May 2003), commonly referred to as El Yeyo, was a Mexican suspected drug lord and former high-ranking member of the Gulf Cartel, a criminal group based in Tamaulipas, Mexico. Prior to his involvement in drug trafficking, López Falcón owned a flower business in Miguel Alemán. He was part of the cartel during the 1990s and was a trusted enforcer of the former kingpin Gilberto García Mena. López Falcón's role in the cartel was managing drug shipments from Tamaulipas to the United States. Security forces believed López Falcón was not a violent crime boss; he preferred to indulge in his personal interests, which included promoting music and entertainment, managing his restaurant chains, and running his horse-breeding business. After joining the cartel, he continued to pose as a legitimate businessman to keep a low profile.

In the late 1990s, López Falcón encountered problems with García Mena, who sought the support of the cartel's leader Osiel Cárdenas Guillén to oust him. López Falcón broke ties with the Gulf Cartel and forged alliances with the Sinaloa, Milenio, and Juárez cartels. The Gulf Cartel reportedly blamed López Falcón for the April 2001 arrest of García Mena and plotted to kill him. He fled to Nuevo León, where he established his center of operations. López Falcón survived an attempt on his life a month later but he was killed in Guadalajara in May 2003. His murder remains unsolved, but investigators believe his killers were probably members of Los Zetas, the Gulf Cartel's former paramilitary group.
