What started as a stop at a U.S. Border Patrol checkpoint north of Laredo turned into a roughly 150-mile, multi-county high-speed chase Friday, ending in Atascosa County after deputies put down spike strips. Authorities said the pursuit wound through Duval and McMullen counties, at times pushing back toward Freer, before officers disabled the vehicle on Highway 16 just north of FM 140. Two people were arrested and are expected to face multiple felony charges, while two others were taken into federal custody, as per WOAI.

How the chase unfolded

According to WOAI, the chase began when a vehicle was flagged at a Border Patrol checkpoint north of Laredo and sped off toward Freer, drawing in local and state units along rural highways. Atascosa County deputies later deployed spike strips on Highway 16 just north of FM 140, bringing the roughly 150-mile pursuit to a halt. Two people were arrested at the scene and two others were turned over to Border Patrol for processing.

Part of a broader pattern

Long, high-speed chases tied to suspected human-smuggling runs have become a recurring hazard along South Texas corridors, where state troopers and local deputies routinely coordinate with federal agents. Recent episodes, including a DPS PIT maneuver that stopped a smuggling run in Webb County, highlight agencies' reliance on tactics such as PITs and tire-deflation devices, as reported by KSAT.

Why pursuit tactics matter on rural roads

Pursuits that stretch for miles on two-lane rural roads pose particular dangers for bystanders and first responders, and law-enforcement research repeatedly urges caution when deciding how to end a chase. A review of pursuit data and policies by the International Association of Chiefs of Police found that a substantial share of pursuits end in crashes and recommends more restrictive, evidence-based pursuit policies along with rigorous training for PIT and tire-deflation deployments, according to the IACP.

Legal implications

The two people arrested in the Atascosa County stop will face multiple felony charges, though officials had not released formal counts as of the initial reports. The two migrants taken into federal custody will be processed by U.S. Border Patrol, and prosecutors are expected to review the investigative files to determine any state or federal charges, per reporting from WOAI.
