Key keywords: Chad Eberle, Texas police officer, Mexico custody battle shooting, triple homicide in Mexico, US-Mexico border arrest, cross-border custody dispute, US law enforcement criminal suspect, international extradition request On Tuesday, 34-year-old Texas law enforcement officer Chad Eberle was taken into custody by U.S. Customs and Border Protection (CBP) agents as he attempted to cross back into the United States from Nuevo Laredo, Mexico, just 12 hours after authorities say he fatally shot three people during a heated custody battle over his 4-year-old daughter on Mexican soil. According to official reports from Mexican law enforcement, Eberle traveled into Mexico without prior notification to local authorities on Monday evening, to meet with his former partner, 32-year-old Maria Gonzalez, who had been granted full legal custody of their daughter by a Mexican family court in March 2024 following a two-year legal dispute. The pair had been scheduled to attend a mediated custody modification hearing in a Laredo, Texas, court next month, but Eberle reportedly chose to travel to Gonzalez’s family home in Nuevo Laredo unannounced to demand unsupervised access to the child. Witnesses told investigators that the conversation between Eberle and Gonzalez quickly turned hostile, and when Gonzalez’s 46-year-old brother Carlos Gonzalez and 52-year-old mother Rosa Mendez attempted to intervene to de-escalate the situation, Eberle pulled his service weapon and fired multiple shots at all three adults. All three victims were pronounced dead at the scene, while Eberle fled the residence with his daughter before crossing back toward the U.S. border. The 4-year-old child was found unharmed in Eberle’s vehicle when he was stopped by CBP agents at the Laredo World Trade Bridge port of entry. The San Antonio Police Department, where Eberle had served as a patrol officer for 5 years, released a statement on Wednesday confirming that Eberle has been placed on immediate administrative leave without pay, and that the department is fully cooperating with both U.S. federal authorities and Mexican law enforcement in the ongoing investigation. Mexican officials have formally submitted an extradition request to the U.S. Department of Justice, seeking to have Eberle returned to Mexico to face three counts of first-degree homicide, as the crimes were committed on Mexican territory against Mexican citizens. Local community groups in Nuevo Laredo have held small vigils for the three victims, calling for a transparent judicial process and accountability for Eberle regardless of his background as a U.S. law enforcement officer. As of Thursday, Eberle is being held in a federal detention facility in Laredo, Texas, pending an extradition hearing scheduled for next week.
