Mystery in West Texas: How did a Border Patrol agent die?

President Donald Trump called it proof of the need to build a wall; Sen. Ted Cruz said it was a “stark reminder” of insecurity along the border.

To everyone, it seemed like a horrendous example of the dangers that Border Patrol officers face as they cover vast, remote and unforgiving territories.

But a month after a middle-ofthe-night incident in which one Border Patrol agent was killed and another, who is said to have no memory of what happened, was severely injured, no one seems to know how the men came into harm’s way off an interstate in West Texas.

It was initially thought to be an attack, perhaps by migrants or drug smugglers. But the FBI says it also was possible the men were hurt accidentally. The Culberson County sheriff, Oscar Carrillo, who is helping with the investigation, seemed to favor that theory when he told The Dallas Morning News that the men could have been hit by a truck.

“If this was an assault, believe me, as sheriff, I’d be the first one out there emphasizing safety in our community and with our deputies, pairing them up,” he told the newspaper. “But from what I know and see, that was not the case here.”

That hypothesis has angered the border agents’ union, The National Border Patrol Council, whose leadership fiercely insists that the men were attacked. Chris Cabrera, a spokesman for the organization, went as far as to call Carrillo a “dingbat” on his weekly podcast.

It was just after 11 p.m. Nov. 18, when, according to the FBI, the two agents at the heart of the mystery responded to unspecified “activity” near a culvert, or drainage tunnel, that carries water underneath Interstate 10 near Van Horn.

One of the agents, Stephen Garland, then called for help. When colleagues arrived, they found both men with major head injuries and broken bones, and took them to a local hospital. The men were flown to a larger hospital in El Paso, where the other agent, Rogelio Martinez, died early the next morning.

Immediately afterward, the FBI said that it would spearhead an inquiry into the incident, which they were treating as a “potential assault against a federal officer,” according to Jeanette Harper, a spokeswoman for the agency. Assaults against Customs and Border Protection officers, including Border Patrol agents, reached 720 in the 2017 fiscal year, the most in at least five years, according to data from the agency.

Harper said the FBI had collected forensic evidence that was being analyzed at its laboratory in Quantico, Va., and was also “aggressively” following up on leads that came into the agency.

One of those led to a search warrant being issued for a car belonging to two brothers. But later, Harper said the agency had not arrested anyone, or even identified anyone “of interest,” in the investigation.

Part of the challenge of establishing what exactly happened to the men is the remoteness of their work. Border agents patrol rocky deserts, often in the middle of the night, where there are very few, if any, other people around. The incident in November happened outside a tiny town of less than 2,000 people. The other agent, Garland, who has been released from the hospital, is said to have no memory of what happened.

Martinez’s father, Jose Martinez, said in an interview shortly after his son died that after seeing his son in the hospital, he thought the injuries were too severe to have been caused by an accident. “I believe someone put a trap,” he said. The elder Martinez said he had often worried about his son working alone in the middle of the night.
