Texas Governor Greg Abbott released the following statement: "With heavy hearts on this Thanksgiving, Cecilia and I express our most honest condolences to the family, colleagues and friends of the trooper who was callously killed today in the line of duty".
Investigators say the shooting happened during a traffic stop.
Black, 45, was apprehended in Hempstead, more than 100 miles from the scene of the shooting, by the Waller County Sheriff's Department. Authorities say Allen was shot with a rifle and died at the scene.

The informant said that he, Lopez-Abrego and eight other MS-13 gang members lured the victim to Wheaton Regional Park this spring. They said he had a "missing bottom tooth near the front of tooth" that "would have been obvious when he was speaking or smiling".
Texas Attorney General Ken Paxton has released a statement that says: "I am saddened to hear of the tragic death of a Texas Department of Public Safety trooper killed today in Freestone County". Officials say Black is being treated for non-life-threatening injuries. According to online jail records, Black is also being held on no bond on a charge of evading arrest in Anderson County, along with bonds totaling $400,000 dollars on Smith County charges of evading arrest and aggravated assault of a public servant.
The suspect has been identified as 32-year-old Dabrett Black. The gunman then fled.
Following news of the trooper's death, Waller County Sherrif's Office said on Facebook that they were saddened by the death of a "brother".
Freestone County is about 90 minutes south of Dallas. After the trooper returned to his patrol unit, DPS officials believe the suspect fired multiple shots at the trooper.
