The first group of Texas National Guard troops moved into a new 80-acre base being built in Eagle Pass as part of Texas' $11 billion border initiative.
On April 14, a National Guardsman assigned to Operation Lone Star "discharged a weapon in a border-related incident," the Texas Military Department said.
Authorities said the Guardsman turned around at a Border Patrol checkpoint and fled, leading to a 15-mile chase at speeds of more than 100 miles per hour.
