Very similar to events in 2006 when the Cartel del Golfo arranged a celebration of children on Dia del Nino, at that time organized by Osiel Cardenas Guillen, El Mata Amigos, Sicarios under the orders of El Flaco Sierra, Juan Gabriel Sierra, toured some sectors of Reynosa delivering gifts.


This has also been done in this area by Los Zetas, during the PAN leadership of the city. The gifts were well received on social networking.

It was not received well by all though with Carmen Electra tweeting the following:
" The toys that were presents from El Flaco Sierra are pools of blood of innocent people, and from the earnings of kidnapping".




In respect of the 2006 event, the Secretary of the City Council, Horacio Ortiz Renan, who is today President of the Superior Court of Tamaulipas, permitted capo Osiel Cardenas Guillen to have a celebration of the Dia del Nino in the Admiral Adolfo Lopez Mateos stadium, counting on the complacency of the then mayor Garcia Cabeza de Vaca and Ortiz Renan, the same notary  who had office in 2016.

Valor Tamaulipeco reports on some of El Flaco Sierra less altruistic and more nefarious activities

In social networks circulated audio recording of reported gun battles in the Rincon de Las Flores, Viaducto, and Lopez Portillo colonias and early in the morning in Puerta Grande, Juarez and La Esperanza colonias among others.

The confrontations started that afternoon in the Vista Hermosa colonia when a convoy of armed subjects confronted the military and had one of their members killed. Later in the colonia Loma Bonita, two armed groups started the first criminal on criminal confrontations of that day.

According to social groups, the confrontations derived from the invasion of an armed group headed by El Flaco Sierra into the El Charco common ground, where they fired on ranches and started fires.

Apparently the territory was defended by the group headed by Petronilo Moreno Flores, El Panilo, who later sought revenge with a caravan of more than 20 vehicles into the south zone of the city which provoked more gun battles.

Otis: this may be a case of mistaken identities, with some claiming that El Flaco Sierra is not Juan Gabriel Sierra, but Juan Gabriel Montes Zermeno, Gabi Montes, or Commandante Sierra, leader of the south zone of Tamaulipas for the CDG, detained in Guadalajara in 2012 and allegedly set free last year.

The internal struggle that El Panilo now has is with Luis Betancourt alias Flaco Sierra originally of San Fernando in charge of a sector of Reynosa and detained in March of 2014 and recently set free at the end of 2017.
