Alleged Zetas narco gang member Enrique Aurelio Elizondo admits to participating in 75 murders...in the past 3 years...including the horrific kidnapping and killing of 36 random bus passengers in Cerralvo in January 2011.
Police speculate that he may actually have killed over 100 people.
Los Zetas often stopped intercity buses near the border to force males to become gunmen, demand money and kill rival gang suspects.
