ZACHARY – Police say a man charged with the murder of a Zachary High student may have had a criminal connection to the 15-year-old victim. 

Terry Flanagan, 58, is accused of committing a number of other crimes in the weeks leading up to the deadly shooting at his home. Police say Flanagan was involved in numerous thefts at an area Walmart in the month of September, stealing multiple televisions. 

In addition to the new charges, police revealed new details surrounding the night that Flanagan shot and killed 15-year-old Chaldrion Brooke-Spurlock. According to Zachary police, Brooke-Spurlock and two other teens were burglarizing Flanagan's home when he returned from work. Police added that Flanagan and the three teens may have known each other in a criminal capacity.

On Wednesday, the Zachary police chief revealed that Flanagan may have been familiar with the teens who were at his house.

"There's an indication that they knew what he was doing," Chief David McDavid said. "And there's a possible indication they were involved also."

According to police, Flanagan returned home after he received a call at work telling him that someone was apparently burglarizing his property. As Flanagan pulled up to his home, two of the teens were still inside. The third, 15-year-old Brooke-Spurlock, reportedly jumped out of a window upon Flanagan's arrival. Police say Flanagan spotted the teens and shouted "I got you b**ches!" before opening fire on Brooke-Spurlock.

Flanagan allegedly shot the teen in the side, walked up to him as he was lying on the ground and shot him again, killing him. Police say he then moved the body out of his yard and onto a neighboring property.

"We felt like Mr. Flanagan's life was not in danger," Chief McDavid said. "He should have called us... And he probably wouldn't be in this situation he's in right now."

The police chief says Flanagan also opened fired on the other two teens as they too jumped out of a window of his home.

Melvin Brooks, 18, and Dwighttess Thomas, 19, were later arrested in connection with the burglary. According to police, the teens were involved in at least 10 car burglaries throughout the area. Thomas is additionally charged with a drive-by shooting that occurred on Chestnut Street earlier this year.

On Tuesday, the WBRZ Investigative Unit uncovered Flanagan's own extensive criminal history, revealing he was supposed to be serving a life sentence as a habitual offender for various crimes in western Louisiana dating back to 1978.

But Flanagan was released in February 2016 after being transferred from the State Penitentiary to another parish work release program. A provision in the law allowed for his release and assigned him to a near life-long parole.

When asked about Flanagan's previous release during a Wednesday news conference, Chief McDavid said the situation was "very frustrating."

"We've had a lot of individuals here in town who have committed crimes who had no business being out of jail," McDavid said. "I understand they're trying to do citizen reform... They need to take a very serious look at these individuals they're letting out and see if they are dangerous to society. Everyone we've dealt with has been dangerous to society here in Zachary and it's causing a lot of problems." 

Flanagan was arrested and charged with second-degree murder and possession of a firearm by a convicted felon.

The State Department of Corrections said there is currently a parole hold on Flanagan, meaning he won't be allowed out of jail in the near future.
