A Wisconsin mom died in a suspected road rage incident over the weekend while teaching her teenage son how to drive, authorities said. Tracey Smith, 46, was giving her 17-year-old son a driving lesson on Friday evening when the pair got into what investigators described as "a minor accident," according to the Milwaukee Police Department. Things took a tragic turn when Smith, a sergeant with the Wisconsin Department of Corrections, got out to confront the driver who ran into them. The two exchanged words and Smith was shot during the encounter, according to police.
