A U.S. Border Patrol agent shot and killed a man suspected of human smuggling in Texas after he struck an agent with his vehicle while trying to escape the scene, federal authorities said Saturday.

Border Patrol agents, Immigration and Customs Enforcement officials and the Webb County constable's office intercepted a tractor-trailer and a vehicle dropping off a large number of people in Laredo around 9:30 p.m. Friday, Chief Patrol Agent Matthew Hudak said.

The people, believed to be in the U.S. illegally, were being loaded into the tractor-trailer, according to Hudak. While agents were interviewing suspects at the scene, a second vehicle arrived on the scene.

“As it got close enough to realize the smuggling load had already been intercepted, the driver aggressively put his vehicle in reverse, trying to flee the scene,” Hudak said.

The vehicle hit a parked car, pinning a Border Patrol agent and a suspect he was interviewing between the two vehicles.

Other agents then opened fire, shooting the driver, who was pronounced dead at the scene. Two others inside the vehicle were injured and taken to a hospital. The injured agent was rushed to a hospital with “significant” leg injuries, and was released Saturday, Hudak said.

“Over the last couple of weeks, we talked about the aggressive tactics being used by smugglers, and this is a very dangerous example of those tactics being escalated to an extremely dangerous level,” Hudak said.

The shooting is being investigated by Laredo police, the FBI, the Border Patrol and ICE.

It was the second fatal shooting involving Border Patrol personnel on Friday.
