According to Human Rights Watch: "on November 14, 2008, Army soldiers entered the home of brothers José Luis and Carlos Guzmán Zúñiga in Ciudad Juárez, Chihuahua, and arbitrarily detained them. The brothers have not been seen since. After conducting an in-depth investigation into the crime, the National Human Rights Commission concluded that "the diverse evidence gathered in the case documents make it possible to prove that the arrest and subsequent disappearance of José Luis and Carlos Guzmán Zúñiga is attributable to Army officials.” However, according to SEDENA, military prosecutors are investigating the case as a crime of “abuse of authority,” which the military defines as “a soldier who treats an inferior in a way that violates legal norms.” More than four years after military prosecutors opened an investigation into the case (on January 14, 2009), no soldiers have been charged, according to SEDENA." ^[+]
