Somebody really, really wanted to see retired Gen. Mario Arturo Acosta Chaparro dead.

Back in 2010, a gunman intercepted and shot the retired army general in the gut in the Roma neighborhood of Mexico City. He survived.

He didn't survive a second attack, which came Friday afternoon as he descended from his chauffeured vehicle to pick up his Mercedes Benz (how many generals can afford to buy MBs?) in a suburban area of Mexico City. A guy in a motorcycle fired 3 rounds from a 9mm handgun into Acosta's head.

During his military career, Acosta was accused both of human rights abuses in a campaign to quell leftist guerrillas in the 1970s and 1980s and of links to the head of the Juarez narcotics cartel in 2007 a panel of judges overturned his conviction.

Acosta is not the only general to be gunned down in recent years. Last May, gunmen killed the recently retired No. 3 general, Jorge Juarez Loera, in suburban Mexico City. Assailants tortured and executed another retired general, Mauro Enrique Tello, near Cancun in 2009. Tello had just assumed a civilian public security post in the area.
