Juan Francisco Murillo Díaz
Juan Francisco Murillo Díaz, also known as "El Güero Jaibo" (Mexican Spanish slang: "Tampico Whitey"), was a member of the Tijuana Cartel (Arellano Félix Organization), believed to be one of the masterminds and shooters behind the assassination of Cardinal Juan Jesús Posadas Ocampo in Guadalajara, Jalisco, in May 1993. Although he was never arrested, Murillo was identified as the actual shooter, along with Édgar Nicolás Villegas, AKA "El Negro" (The Negro).
Other cartel members
Murillo's nephew, Ulises Murillo Mariscal, also a member of the Arellano Félix Organization, was arrested in 1994 at his home in Guadalajara, Jalisco, for possession of cocaine and several firearms. Still at large and unidentified is Murillo's other nephew, known only as "El Tiburón" (The Shark). He is believed to be living in the United States, in either San Diego or Chula Vista, California.
In August 2006 the D.E.A. and U.S. Coast Guard captured the suspected leader of the Arellano Félix Organization, Francisco Javier Arellano Félix, AKA "El Tigrillo" (The Wildcat), along with his lieutenant Arturo Manuel Villareal Heredia, AKA "El Nalgón" (The One with Big Ass).
