Baltazar Sauceda Estrada—known as “El Mataperros” (The Dog Killer)—a leader of the Los Zetas cartel who ordered the 2011 attack on the Casino Royale in Monterrey, filed an *amparo* (constitutional protection) petition because authorities at the Altiplano prison would not allow his family to send him sneakers via courier service.
Sentenced to 135 years in prison for organized crime, drug-related offenses, and aggravated kidnapping, “El Mataperros” sought judicial protection from the Second District Court for Criminal Matters in the State of Mexico (based in Toluca). He challenged the refusal by the director of Federal Social Readaptation Center (CEFERESO) No. 1 “Altiplano” to allow his family to send him sneakers by courier.
However, Azucena Lazalde Íñiguez, the Second District Judge for Criminal Matters in the State of Mexico, dismissed the *amparo* petition filed by Baltazar Sauceda Estrada—one of the masterminds behind the Casino Royale attack, which resulted in 52 deaths.
In July of last year, “El Mataperros” was sentenced to 135 years in prison for organized crime offenses (specifically involving drug trafficking and kidnapping, with roles involving administration, direction, and/or supervision) and for unlawful deprivation of liberty in the form of kidnapping, involving three victims. He was also fined 1,264,327 pesos.
In August 2011, members of the Los Zetas criminal group set fire to the Casino Royale in Monterrey after the owners refused to pay extortion fees—known as *cobro de piso*—to the group, which is one of the most violent in the country.
