A man named Jorge Zavala and a 22-year-old man were victims of an attack perpetrated by unknown shooters traveling in a dark-colored SUV from a Chevrolet Tahoe, causing them to lose control of the vehicle and crash along the expressway. The local police did not find a motive for the attack, but sources told '' The Monitor'' that Zavala had ties with a faction of the Gulf Cartel in the Mexican border cities of Matamoros and Reynosa, showing signs that his assassination was due to an "internal power struggle" in the organization. Zavala died instantly at the scene, while the other man was taken to the hospital in critical condition. The McAllen Police Department refused to comment on how many gunshots were fired, but the preliminary autopsy revealed that Zavala died of multiple gunshots, not from the crash. Public records prove that Zavala's criminal history dates back to 1995, while sources familiar with the victim stated that he was a close associate of the drug lord

The process did not go as planned and the gang members ended up kidnapping a group of dealers, leading to a shootout incident. The sheriff said that this "represents the only direct spillover" case of Mexico's drug war in South Texas, but stated that it was not directly related to Mexico. After this incident,

, a large-scale prison riot left 20 inmates dead and 12 others wounded. The brawl broke out between two inmates at around 8:00 a.m. but later extended to the rest of the prison. In the turmoil, the Mexican federal police and the Tamaulipas state police were summoned to help the guards regain control of the prison. The Mexican military later took control of the prison at around 10:30 a.m. News videos showed helicopters in the air over the watchtower. Later in the morning, the family members gathered outside the prison to await the news of their loved ones while Mexican authorities set up a booth to take care of their requests and inquires. According to '' The Monitor'', sources confirmed that the prison brawl was related to the fight between the Metros and the Rojos.

Zúñiga Hernández's arrest

On 1 November 2011 in the city of Santa Maria, Texas, José Luis Zúñiga Hernández (''Comandante Wicho''), a high-ranking member of the Gulf Cartel, was arrested in Santa Maria, Texas on 26 October 2011 by U.S. Border Patrol agents. During his arrest, Zúñiga was carrying cocaine, $20,000 US dollars in cash, and a gold, diamond, and ruby encrusted .38 Super Colt handgun. The pistol has the name "Wicho" encrusted on it. He also "freely admitted" to be a Mexican national without documents to reside in the United States, while sources familiar with Zúñiga Hernández indicate that he turned himself in to American authorities. His attorney testified that ICE agents coerced Zúñiga Hernández to confess his crimes and cooperate with them in exchange for protection to his family and immunity from prosecution. The ICE agents denied such claims, however. Zúñiga Hernández was the cartel boss in the city of

Ten bodyguards of Costilla Sánchez were also arrested during the operative. Ernesto Banda Chaires, one of the detainees, is believed to be the regional boss of the cartel in Tampico. In the Wednesday arrest, the Mexican authorities confiscated several assault rifles, pistols encrusted with jewelry, and a number of expensive-looking watches. When asked if he had anything to say about his criminal charges and if he had a lawyer, Costilla Sánchez shook his head.

, had been reclusive and never had a permanent spot, often retreating to one of his ranches where he gives orders. Costilla Sánchez never got involved in the day-by-day operations of the cartel, but it seemed unlikely that he will be replaced, given Mario's arrest and past behavior. In early 2012, the infighting between the Rojos and the Metros that left bloody confrontations and high-ranking arrests has diminished. Nonetheless, the Gulf Cartel had to change its logistics and reconstruct how it manages regional bosses, while other sources say that the Rojos are no longer part of the cartel. In the end, the control fell to the cartel members of the Metros faction, although the Rojos still has significant manpower. The Rojos and the forces loyal to the Cardenas drug family have barricaded in

on 6 August 2012, gunfighting occurred in the city, and the Metros' push in Matamoros is a sign that they are determined to remove people who turned against the organization in the past.

To be sure, any drug trafficking organization is vulnerable to attacks when infightings occur, but the Gulf Cartel's feud with

will compound the problem and make the infighting even more volatile. The infighting and struggle between the Gulf Cartel and Los Zetas has surely weakened both organizations, but Los Zetas continue to control key territories in Tamaulipas and seems to have the advantage of recruiting seemingly limitless gunmen from South America, while the Gulf Cartel is opting for young, less-experienced recruits from its territories.

leaves the Gulf Cartel without a definite successor. Both arrests in effect wipe out the traditional old-time bosses of the cartel, putting an end to a generation of drug traffickers. When Cárdenas Guillén was arrested on 4 September 2012, it looked as if Costilla Sánchez had finally won the leadership of the Gulf Cartel. Throughout the end of 2011 and until the time of his arrest in 2012, Costilla Sánchez had carried out a campaign to put down Cárdenas Guillén and his faction – the Rojos – by reportedly setting up its members to get arrested or killed. His attempts to successfully put down his rivals allegedly gave him the protection of some high-ranking officials in the

reportedly betrayed him and notified the authorities of his whereabouts. It is also possible Cárdenas Guillén's declarations resulted in the apprehension of Costilla Sánchez too. Without a clear successor of Costilla Sánchez, his faction – the Metros – could come to an end, although it is still likely that there are other old-crime boses of lesser importance still trying to keep the Gulf Cartel standing.
