The vehicle they’d targeted belongs to Norman Woodley.

“This homeland security person who lives next door in the neighborhood spotted them, and I guess they shot him in the arm,” Woodley told WWJ Newsradio 950 at the scene. “He’s, I guess, in the hospital recovering; thank God. And that’s all we know.”
