Speaking of ghosts El Azul could be also still alive one of the founders of Sinaloa Cartel.
Originally a member of the Federal Directorate of Security (DFS), he founded the Guadalajara Cartel in the 1970s along with other major drug traffickers in Mexico. After its disintegration in 1980, he led the Juárez Cartel , allying it with the Sinaloa Cartel.
His death is presumed to have occurred in a Mexico City hospital due to cardiac arrest, but authorities have not yet been able to confirm or deny this theory.
I think its pretty much known that El Azul is actually dead, but you never know with these guys. A lot of speculations were about death of Heriberto 'Z-3' Lazcano, some people still believe he is alive.
