BROWNSVILLE — Federal immigration authorities are treating Joel Luna, a Border Patrol Agent accused last month of capital murder and drug cartel ties in deep South Texas, as a potential foreign national subject to deportation, The Texas Tribune has learned.
In an unusual move, U.S. Immigration and Customs Enforcement has targeted the federal agent with a “detainer” — basically a civil arrest warrant filed against non-citizens — at the Cameron County jail. As a matter of law, ICE has no civil immigration enforcement authority to arrest or detain a U.S. citizen.
The detainer adds a surprising twist to a case that has already generated national headlines and focused attention on U.S. law enforcement corruption along the southern border.
Luna, two of his brothers and two other South Texas men have been indicted on capital murder and other charges stemming from the murder and beheading of a Honduran national, whose body was found during spring break last year near South Padre Island. Investigators say the men had ties to the powerful Gulf Cartel.
After Luna was arrested last year, the Cameron County sheriff's office said investigators found more than a kilo of cocaine, $90,000 in cash, firearms and Luna’s Border Patrol badge in a safe at the home of his mother-in-law.
The five men are scheduled to be arraigned in state district court in Brownsville on Wednesday. Garcia said Joel Luna will plead not guilty on all charges and ask for a jury trial.
Now a new wrinkle has emerged in this case: Luna has two birth certificates, one from Hidalgo County, Texas, the other from Reynosa, Mexico — right across the Rio Grande River.
ICE did not immediately return phone calls, but Luna’s lawyer, Carlos A. Garcia, said he has no doubt that his client is a U.S. citizen, an ironclad requirement for employment as a Border Patrol agent. Garcia also denied a statement from U.S. Customs & Border Protection asserting that Luna had been "arrested on False Claim To United States Citizenship" on Nov. 12, when the agent was already in state custody in South Texas.
He said any federal arrest would trigger an appearance before a magistrate within 48 hours and notification to him as Luna's lawyer — and "none of that occurred," Garcia told the Tribune.
“He worked for the federal government. No one had ever questioned his citizenship before — until his arrest,” Garcia said. “I don’t put much value in whoever it was that made that determination. You have one person that decided that, you know what, this is worth a second look.”
Garcia said Luna attended elementary school in Mexico, which has stiff paperwork requirements for children who want to enter the public school system there. He said it’s not uncommon for parents or other relatives to fraudulently obtain Mexican birth certificates.
“Mexicans who live along the border can purchase a birth certificate by just showing up one day and saying, 'Hey, my kid was born on this date in this place,'” he said.
In Luna’s case, the U.S. birth certificate was filed two days after his birth on May 20, 1985. The Mexican birth certificate was issued in August of 1988, a little over three years after his birth was reported in San Juan, Texas.
The Texas Tribune has obtained both documents. The Mexican one came from authorities in Ciudad Victoria, the capital of the state of Tamaulipas, where birth certificates are considered public records. Garcia provided the Tribune his American birth certificate. The existence of the Mexican birth certificate potentially suggests that Luna has dual citizenship.
Border Patrol Agent Joel Luna, indicted for capital murder, has two birth certificates, one saying he was born in Mexico, the other saying he was born in Texas. Luna's lawyer says he was born in Texas.
“I don’t know whether or not my client has Mexican citizenship per se, but there is a Mexican birth certificate out there,” Garcia said. "He left Mexico a long, long time ago when he was very young. It’s unfortunate that we have this little wrinkle, but it's there."
It's at least the second recent case involving a federal border agent holding both Mexican and U.S. birth certificates. In another case of alleged law enforcement corruption at the border, the Monitor newspaper of McAllen reported Tuesday that a Customs and Border Protection agent accused of taking a bribe also has competing birth claims on both sides of the border.
