FAIRFIELD, Texas — The Texas Department of Public Safety has identified the trooper who was shot and killed during a traffic stop in East Texas Thursday afternoon.

DPS released a statement on its Twitter page identifying the trooper as 41-year-old Damon Allen. The agency says Allen joined the department in 2002 and was married with three children.

"Trooper Allen's dedication to duty, and his bravery and selfless sacrifice on this Thanksgiving Day, will never be forgotten," the department said.

The department also says it will file capital murder charges against the suspect, 32-year-old Dabrett Black. He was taken into custody Thursday night in Waller County, more than 100 miles south of where Allen was shot.

Authorities say Black is being treated for non-life-threatening injuries following his apprehension.

The shooting occurred about 4 p.m. Thursday south of Fairfiled, along Interstate 45 in Freestone County.

Texas Attorney General Ken Paxton issued the following statement:

I am saddened to hear of the tragic death of a Texas Department of Public Safety trooper killed today in Freestone County. This trooper died selflessly serving Texas. Please join Angela and me as we pray for the trooper’s family and for the entire Department of Public Safety.
