Meet Holly Schnobrich. The Indiana woman's mind was clear enough to know she was in no state to get behind the wheel of her car Saturday. But her judgment was so clouded--likely by the painkillers and sleeping pills she had been ingesting--that she tabbed her five-year-old son to act as her designated driver. According to the below probable cause affidavit filed in Tippecanoe County Circuit Court, a neighbor watched as a 2002 Mitsubishi sped around the corner and "screeched to a stop in front of her home." At the wheel was the young boy and his passengers: his 24-year-old mother, who was in the front passenger seat, and his three-year-old brother. When her neighbor asked if the child had been driving, Schnobrich replied, "He's a good driver."
