On the night of December 11, 2025, on a private ranch in Starr County that other outlets have placed roughly 5.7 miles west of the Rio Grande City port of entry, a 31-year-old man from a poor, rural stretch of southern Mexico lay bleeding from three gunshot wounds while a Border Patrol agent radioed for backup. He had crossed the river for the first time in his life. He had no criminal record in the United States. He had no family here waiting for him. Within the hour, Isaias Sanchez Barbosa was dead.

Six days later, U.S. Customs and Border Protection posted a short notice online. Agents had been conducting "targeted enforcement." They had spotted a group of people "in camouflage" near the riverbank. When agents approached, the notice said, the group "attempted to abscond to Mexico." A struggle broke out. An agent shot Sanchez Barbosa. CBP called it self defense and moved on.

Eight months later, that six-day-old press notice is still almost everything the public knows. A Starr County grand jury declined to indict the agent involved in June 2026. District Attorney Gocha Ramirez says the criminal case is closed. But the Texas Rangers and CBP's own Office of Professional Responsibility are still investigating, for what officials describe only as "administrative reasons," and neither agency has released the body camera footage, the dash cam video, the radio traffic, or the incident reports that would let the public see what actually happened on that ranch. Reporting by the Texas Tribune and KRGV, drawing on autopsy records, a search warrant, and on-record interviews with the district attorney and outside experts, has pieced together more of the story than CBP ever volunteered. It is still an incomplete picture, and the agency that controls the missing pieces has shown no urgency about filling it in.

Starr County's relationship with federal immigration enforcement runs deeper than almost anywhere else in Texas. The Rio Grande City Border Patrol station polices ranch land, brush country, and river crossings that make up one of the more active stretches of the Rio Grande Valley sector, and local law enforcement works alongside federal agents as a matter of routine. That proximity cuts both ways. It is why Texas Rangers, a state agency, were the ones deputized to run the criminal investigation into a federal agent's shooting, a common arrangement in officer involved shooting cases across Texas because it puts the review one step removed from the agency whose agent pulled the trigger. But the county district attorney's office still sits inside that same web of daily cooperation. Ramirez telling reporters the criminal case is closed, without his office having spoken to the victim's family, fits a pattern local prosecutors in border counties have followed for years: a fast, quiet resolution that keeps the working relationship with federal agencies intact.

CBP's Office of Professional Responsibility, the branch of the agency reviewing the shooting for what DPS spokesperson Ericka Miller called "administrative reasons," answers to CBP leadership, not to an outside civil rights body. It is not a court. It does not hold public hearings. Its findings, when it produces them, are not automatically released to the public or to the family of the person an agent killed. That structure is not unique to this case. It is how CBP has investigated its own agents' use of force for years, and it is the reason a shooting can clear the criminal system in six months while the only body examining the underlying policy questions, whether the agent followed training, whether deadly force was proportional, whether Flores should still be armed and patrolling, operates on a timeline it sets for itself and answers to no outside deadline.

The paper trail that does exist tells a specific story. An autopsy obtained by the Texas Tribune from the district attorney's office describes close range gunshot wounds to Sanchez Barbosa's right and left chest and his right forearm, a fractured left rib, and both lungs torn. He was found in a green, torn, blood stained shirt, black underwear, and black tennis shoes. CBP's own account puts the entire encounter, from the moment agents approached the group to the moment an agent radioed for help reporting a fight, at about four minutes.

Texas Ranger Bryan Rodriguez, the lead investigator, sought a search warrant in December looking for "bludgeons, clubs, club like instruments, and blunt like instruments," the kind of evidence that would support CBP's claim the agent faced a physical threat. Ramirez has confirmed that search turned up no weapons. That is not a small detail. It means the government's own criminal investigation, the one it now calls closed, could not find a weapon to back up the reason it gave for using deadly force.

Court records reviewed separately by the Tribune and by KRGV identify the agent who fired the shots as Armando Flores. CBP has never named him publicly. In fact, in the hours after the shooting, another Border Patrol agent, Jawuan Wallace, was fingerprinted at the scene at 11:25 p.m. CBP later confirmed Wallace was not the shooter, but the agency has declined to answer basic questions about Flores directly: how long he had been with Border Patrol, what training he had received, whether he was interviewed as part of the internal review, and whether he remains on active duty patrolling the same stretch of river. Eight months after the shooting, CBP has not answered any of it.

Sanchez Barbosa's own family could not be reached by either newsroom that reported this story. The Mexican consulate that arranged to repatriate his body did not respond to questions from reporters, and neither did Mexico's Foreign Affairs Ministry. No attorney has surfaced publicly to represent the family. That silence is its own kind of finding. A man crossed into Texas for the first time, was shot three times by a federal agent, and eight months later there is no public record of his family's account of who he was, why he crossed, or what they have been told about how he died. The people with the least power in this story, a family in rural southern Mexico with no legal representation and no fluency in the U.S. system that killed their relative, have had no voice in it at all.

The people who have spoken are outside experts with no direct stake in the case. Chris Magnus, who ran CBP under the Biden administration, told the Tribune he questions whether the shooting was proportional to the threat CBP described. "Somebody is trying to run from you back to Mexico," Magnus said, "how would deadly force be a proportional response?" He also asked the more basic question CBP's own notice never answered: "Was there any attempt made to avoid the use of force?" David Bier, who studies immigration enforcement at the Cato Institute, put the case in a broader frame. "This case had all the hallmarks of those later cases," Bier said, "an apparently unarmed victim who was retreating, a quick DHS statement exonerating the agent, and very few other details." Bier's use of the word "later" is worth sitting with. He was describing a pattern that Sanchez Barbosa's death came before, and that other deaths have since confirmed.

That pattern is documented, not speculative. Since President Trump's second term began, federal immigration officers have fatally shot at least five people nationwide, and Sanchez Barbosa's death is one of them. Renee Good, a U.S. citizen, was shot by an ICE officer in Minneapolis on January 7, 2026. Alex Pretti, also a U.S. citizen, was shot by CBP in Minneapolis on January 24, 2026. Silverio Villegas Gonzalez, a 38 year old Mexican national, was shot by federal agents in Chicago on September 12, 2025. Keith Porter, a 43 year old U.S. citizen, was shot by an off duty ICE agent in Los Angeles on December 31, 2025. At least eight more shootings by immigration officers caused injuries without killing anyone, in cities including Portland, Chicago, and communities in Arizona and Minnesota. Separately, 32 people died in ICE custody in 2025, described by researchers as a two decade high.

Texas has its own smaller pattern inside the national one. In March 2025, an ICE agent shot Ruben Ray Martinez, a U.S. citizen, during a traffic stop on South Padre Island. A grand jury declined to indict that agent too, but the Texas Department of Public Safety released body camera footage from that shooting relatively quickly. In July 2026, an ICE agent in Houston shot and killed Lorenzo Salgado Araujo, again claiming self defense, again with no body camera footage available because, according to reporting, the involved officers were not wearing one. Sanchez Barbosa's case sits inside that same pattern, an unarmed man, a claim of self defense issued within days, and a records vacuum that has now lasted eight months. The Department of Homeland Security's general public position is that its officers use only the "minimum amount of force necessary." Critics, including researchers who track these cases nationally, argue that federal immigration enforcement operations under the current administration are producing violent confrontations by design, not by accident.

Here is what accountability requires and what has not happened. The Starr County grand jury heard whatever evidence Texas Rangers and CBP chose to present, in secret, and declined to indict. That process, whatever its outcome, is now closed to public scrutiny by law. What remains open, and what the public still has a right to see, is different: the body camera footage if it exists, the radio traffic from the four minutes CBP itself says the encounter lasted, the incident reports Rangers wrote, and a straight answer about Agent Armando Flores's status today. CBP's Office of Professional Responsibility, the agency's internal affairs arm, is reportedly still reviewing the case for "administrative reasons," a phrase DPS spokesperson Ericka Miller used without further explanation. Eight months is a long time for an internal review with no public deadline and no public findings. Neither the Texas Tribune's reporting nor KRGV's found any indication that the FBI or the Justice Department's Civil Rights Division has opened an independent review of the shooting. If no outside federal civil rights investigation exists, the only bodies examining a federal agent's decision to use deadly force on U.S. soil are the same agencies he works for and the county DA who works alongside them every day. CBP did not answer reporters' questions about Flores's training, his interview status, or his current assignment. That refusal is itself an answer, just not the kind that closes a case.

Somewhere in southern Mexico, a family that has never spoken publicly is living with a green, torn, blood stained shirt as one of the last images of a son, a brother, or a father who crossed a river for the first time and did not live to explain why. CBP's own account says the whole encounter lasted about four minutes. Eight months later, the government has offered the public less information than it took the agent to reload.
