The estranged wife of Dabrett Black, the alleged gunman who shot and killed DPS Trooper Damon Allen, told Channel 6 News she saw warning signs and paranoia from Black for a long time.

"I've been trying to tell people this for years," Black's wife, who spoke with Channel 6 News on terms of anonymity to protect her family, said. "I don't know why (Black) was released ... recently. He's had nothing but history. I really feel for that cop's family because now their Thanksgiving is ruined every year."

Public records show Black had ties with Central Texas.

Black was previously arrested in Bell County for possession of less than two ounces of marijuana.

Records also indicated Black was in the Army for a number of years, and his estranged wife said Black served three tours in Iraq. She said Black "returned a changed man."

Black was captured Thursday evening in Waller County, northwest of Houston.

Shots were reportedly fired in the area where Black was spotted fleeing on foot. Texas DPS troopers and multiple law enforcement agencies cornered Black before he was safely taken into custody at about 9 p.m. Thursday.

Black was booked into Brazos County Jail and charged with capital murder of a peace officer. His bond was set at $500,000.
