More Details on Background of Trooper Killing Suspect

BRYAN (ABC/Staff) – We’re learning more about the background of Dabrett Black of Lindale. Black faces a capital murder charge in the shooting of Texas Trooper Damon Allen during a traffic stop on Thanksgiving Day. Black’s friends and parents describe a high school graduate who followed in his father’s footsteps and joined the Army. But after three tours of Iraq and a head injury from a bomb blast, the people around Black noticed memory loss, paranoia and violence. It all culminated on the side of a Freestone County freeway on Thanksgiving Day, when, police say, Black pulled a rifle on the state trooper who’d pulled him over and shot him to death. Allen will be buried Friday.
