A 21-year-old man from Reynosa, Mexico, who was arrested crossing the Rio Grande into Mission, Texas, back in July is now facing federal terrorism charges over his alleged role as an armed enforcer for the Gulf Cartel, including allegations that he helped dispose of human remains. Jose Flores Flores pleaded not guilty to the charges during a court appearance in McAllen, and the case marks one of the first tests of a legal strategy federal prosecutors are now using along the South Texas border.
Flores Flores was initially arrested by U.S. Border Patrol agents on July 10 after allegedly crossing illegally between ports of entry, according to Breitbart. Federal prosecutors first charged him with a single count of illegal re-entry tied to prior immigration violations, but prosecutors later obtained a superseding indictment adding terrorism-related material support charges, as reported by KVEO-TV. The escalation reflects a broader shift in how the Southern District of Texas is now pursuing border cases.
What the Indictment Alleges
The superseding indictment accuses Flores Flores of conducting surveillance on law enforcement, working as an armed enforcer, and assisting in the disposal of human remains for the Gulf Cartel in Mexico, per the same account from KVEO-TV. Those allegations form the basis of the material support charges. The Gulf Cartel has been designated a Foreign Terrorist Organization. U.S. Attorney Aaron Reitz announced the charges in a post from the US Attorney SDTX
account, noting that Flores Flores is just one defendant charged so far. Reitz said his office is working to make America safe through the destruction and dismantling of terrorist cartels, and described the Southern District of Texas office as being at the forefront of dismantling terrorist cartels.
The Legal Foundation Behind the Charges
The case rests on Executive Order 14159, under which Secretary of State Marco Rubio designated the Gulf Cartel a Foreign Terrorist Organization on February 20, 2025, according to the Federal Register. Material-support charges were subsequently brought against accused cartel operatives. Flores Flores faces a maximum penalty of up to 20 years in prison. Attorney General Blanche oversees the Justice Department under which the charges were brought, per the US Attorney SDTX announcement.
The criminal prosecutions provide one federal tool for targeting cartel-linked activity.
A Border Hub Across From McAllen
Reynosa, Tamaulipas, is a strategic Gulf Cartel border city where factions engage in migrant smuggling, drug trafficking, and extortion networks along the lower Texas border, according to InSight Crime. That geography places the Flores Flores case within a border corridor where cartel activity on the Mexican side has long spilled into federal enforcement on the U.S. side.
Aaron Reitz now serves as U.S. Attorney for the Southern District of Texas after serving as Assistant Attorney General over the Justice Department's Office of Legal Policy and previously working for Texas Attorney General Ken Paxton, according to the U.S. Department of Justice. Hoodline previously covered Paxton's endorsement of Reitz in his rise to the DOJ post. The office he now leads handles federal cases in the district.
Part of a Broader Enforcement Push
The Flores Flores case follows a string of anti-cartel actions in the district. Hoodline reported last month on enforcement activity in McAllen, and also covered a separate Houston case. Whether prosecutors can consistently link individuals apprehended at the border to organized cartel structures across the river in Reynosa remains a central question for this style of case, as Flores Flores has pleaded not guilty and the matter now moves forward in federal court in McAllen.
