A Walmart shopper steps up to help police catch a shoplifter on the run. It’s captured on surveillance video and it appears the shopper times his moment just right and rolls his shopping cart into the path of the shoplifter. What stands out in the video is the concentration on the part of the shopper. He watches and waits and then sends his cart rolling. Later video shows other shoppers helping him to pick up purchases that are thrown all over the parking lot. And the video shows a pat on the back from the police. He is a mystery otherwise. And Peachtree City police say they appreciate his help. “He was able to help us take him into custody without injury to anyone including the offender,” said Sgt Chris Hyatt with Peachtree City Police.
