MCALLEN, Texas (KVEO) — A U.S. Border Patrol agent was killed in an incident while on duty, federal authorities announced Wednesday.

At about 1 a.m. Wednesday, a Border Patrol agent on an all-terrain vehicle assigned to the McAllen station was tracking a group of people suspected of crossing the border illegally, the agency said. While on the vehicle, the agent was involved in a crash near Mission, Texas.
