On February 4, 1976, the body of Carol Wudarcki was found in Worth Township. She had been struck by a snow plow mere minutes before being discovered by Mark Ernst, making it near impossible for investigators to determine her cause of death. What was curious, however, were the marks found on her ankles and wrists. Just what does Ernst have to do in all of this, and is it possible that he may (or may not) have murdered others, including Iris Johnston and Gladys Barron?
