Louisiana Woman Shot Her Son in the Head, Then Tried to Pretend He'd Kidnapped Her: Police

A woman allegedly shot her son and another friend as they were driving home from a casino in Bossier City, Louisiana, on Saturday night, then tried to pretend that she’d been kidnapped, PEOPLE confirms.

Dora Blake, 47, was purportedly celebrating her birthday when she fatally shot her son, 22-year-old Patrick Hollingsworth, in the head and injured the other woman. Authorities have yet to determine a motive, but investigators said Monday that Blake was “quite intoxicated” at the time of the shooting.

“It appears her intoxication played a big role,” Bossier Sheriff’s Office spokesman Lt. Bill Davis tells PEOPLE.

Hollingsworth was behind the wheel of the car when his mother allegedly opened fire, hitting him and the other woman, who was sitting in the passenger seat. The vehicle then crashed into a tree.

Some Good Samaritans pulled over to help after spotting the car. Blake allegedly told them that she had been kidnapped and had managed to shoot her captors. The witnesses then repeated that story to the sheriff’s deputies who arrived to assist with the crash.

But when detectives interviewed the surviving victim, she told them that the three of them had gone to a casino to celebrate Blake’s birthday, which was on Sunday. “The lady in the front seat, she told us what had happened,” says Davis. “Her son was treating her to a birthday celebration and she ended up shooting him.

He adds: “Why [Blake] did it remains to be seen.”

The female passenger is being treated for her injuries and is expected to recover.

Davis tells PEOPLE that Blake had little recollection of shooting her son. “She just seems confused. If she had any ill will towards him, then she was hiding it very well when investigators first interviewed her,” he says. “But it does make you wonder: Why would a mom do that?”
