A guy I know use to work for UPS years ago. One day while making deliveries, he had to drive through a neighborhood looking for an address. He noticed a lady and a young child walking down the sidewalk headed in the same direction he was. He noticed the lady kept looking back at him and thought it was strange. When he got closer to her, she switched sides with the child. This really set off an alarm with him and he was pretty sure something was up. Sure enough when he got close to them, she suddenly pushed the kid out into the street in his path. Luckily he was on high alert and was able to stop before hitting the child. He immediately called the police but she took off with the child in tow. Don't know if they ever caught her or not. I know it shook him up pretty good.
