Family alleges helicopter gunfire; Navy denies firing
Relatives identified the child as Aranza. She was riding with family members and other children in an SUV near Las Rusias when the vehicle came under fire. A bullet struck her in the head, killing her. Her mother was wounded, reportedly in the foot.
The child's uncle said relatives who were in the SUV alleged that Mexican security forces shot at them from a helicopter. That account has not been independently verified, and investigators have not publicly identified who fired the fatal shot.
Mexico's Navy denied that its helicopter fired or took part in the confrontations. In communiqué 040/2026, issued Oct. 30 by the Matamoros Naval Sector, the Navy said the aircraft was making an administrative personnel transfer and cited flight records in support of its account.
The Tamaulipas Attorney General's Office confirmed Aranza's death and opened an investigation into the shooting, including the family's allegations. State security officials also reported that a child had died during Thursday's violence and that two other people were injured.
Roadblocks linked to fatal crashes
The other five deaths reported by Mexican media involved crashes into vehicles used to block roads. KABB's freelance crew in Mexico independently confirmed that four victims were from Nuevo León. Their vehicle hit a burned bus obstructing the Matamoros-Reynosa highway near Ejido Soliseño. A 3-year-old boy reportedly survived with serious injuries.
Media accounts identified the fifth crash victim as Filiberto. His pickup, reportedly bearing Texas plates, struck a roadblock vehicle near the Los Indios international bridge.
La Jornada also reported a civilian's death in Valle Hermoso after his car hit a burning transport vehicle being used to obstruct traffic. The newspaper reported at least 15 roadblocks involving burning vehicles on Oct. 29 across Matamoros, Río Bravo, San Fernando and Valle Hermoso.
Arrest followed by fires and bridge closures
Federal authorities announced Cárdenas Rodríguez's arrest in Matamoros on Thursday, Oct. 29, 2026, identifying him as the alleged second-in-command of Los Ciclones, a Gulf Cartel faction. He is known as "El Titán" or "Axel." According to Diario Puntual, officers intercepted him in a blue Lamborghini Urus on Avenida Pedro Cárdenas near the Cruz Verde.
After the arrest, armed groups burned vehicles, obstructed major roads and spread spike strips through the streets. Parts of Matamoros ground to a halt. In Río Bravo, businesses shut their doors and schools called off afternoon classes. Authorities also temporarily closed four international bridges linking the region with Texas.
Mexico sent about 450 soldiers and two armed helicopters to the border region in response.
President Claudia Sheinbaum discussed the response to the roadblocks on Friday. "It happened in this particular case. The Defense Ministry and the National Guard have an action plan in case roads are blocked. They have tow trucks and various resources," she said.
Diario Puntual reported that Matamoros Mayor Beto Granados subsequently announced that public transportation was resuming, including city routes and services carrying factory workers. Security forces and civil protection personnel were working to remove the vehicles and debris blocking roads.
Suspect's prior arrest and cartel ties
Cárdenas Rodríguez had previously been arrested on May 7, 2023. In January 2024, a federal judge allowed him to remain free while his case continued.
Security and Citizen Protection Secretary Omar García Harfuch said authorities believe Cárdenas Rodríguez ordered the May 17, 2026, armed attack on federal officers guarding the outer perimeter of the U.S. Consulate in Matamoros. One Mexican officer was killed.
His father is José Alfredo Cárdenas Martínez, known as "El Contador." According to UPI, the elder Cárdenas faces U.S. charges involving trafficking in cocaine, methamphetamine and fentanyl and remains subject to extradition proceedings. Cárdenas Rodríguez is also related to former Gulf Cartel leader Osiel Cárdenas Guillén.
UPI reported that Los Ciclones and Los Escorpiones, another Gulf Cartel faction with ties to the Cárdenas family, have been implicated in the March 2023 kidnapping of four U.S. citizens in Matamoros. The FBI and other U.S. federal agencies investigated that case.
