(MPD) Dr. Walker Wright, pastor of White Stone Missionary Baptist Church, says he was there during the incident. He says he was shocked after saying he had just left the couple to go inside to call for help for the medical incident. When he got back, the truck was already gone, and the couple injured. "I don't think he meant to hurt them, people. I just can't believe he meant to hurt them because if he wanted to hurt them, he would've hurt them," Wright said. "He didn't kill them; he didn't hit them. He just took the truck, and they were too close to the truck. I hate that he did that. Hopefully, he can turn himself in, hopefully, the lady lives." The husband says his wife is now doing better, but says this impacted their ability to get around the city. The truck was a red and white 1991 GMC pickup, Tennessee tag BHV3108. Police are still looking for it. This story will be updated.
