Mario Arturo Acosta Chaparro

Mario Arturo Acosta Chaparro Escápite (19 January 1942 – 20 April 2012) was a Mexican Army general who was shot dead in an incident in Mexico City. He had been incarcerated in the year 2000 for allegedly having ties with the Mexican criminal group known as the Juárez Cartel; he was later released in 2007 for lack of evidences against him. Acosta was also accused of 143–500 disappearances during Mexico's "Dirty War" in the 1970s.

Acosta Chaparro, son of the Mexican Army general Francisco Acosta Chaparro, was "one of the most controversial military men in Mexico's modern history." He was also one of the most "ferocious" persecutors of guerrilla groups during the presidencies of Luis Echeverría and José López Portillo. Provided by Wikipedia
