A Border Patrol agent driving a marked vehicle gave chase to a pickup truck spotted loading people near the Rio Grande in Laredo, Texas. A Border Patrol statement notes that the agent had lost track of the truck, which later collided into another vehicle (original link):
The pickup immediately left the area at a high rate of speed, causing several people to fall from the vehicle. The BPA radioed to additional BPAs in the area as he attempted to catch up with the white pickup truck. The BPA lost sight of the vehicle and radioed to other agents notifying them that he could not locate the vehicle.
The pickup collided into a SUV at the intersection of Main Avenue and Jefferson Street, approximately 16 blocks northwest of the BPA’s location. Border Patrol EMTs, Laredo Fire Department Emergency Medical Services (EMS), and Laredo Police Department (LPD) responded to the scene of the collision. No Border Patrol units were pursuing the white pickup truck at the time of the crash. The first Border Patrol unit arrived on the scene within a minute and came from the opposite direction without its lights and sirens activated.
The accident killed three people aboard the pickup truck and injured eight. Border Patrol noted, “This incident is being reviewed by the Webb County Medical Examiner’s Office and CBP’s Office of Professional Responsibility and is being investigated by the Laredo Police Department.”
