The story of America's oldest solved cold case

In 1957, Maria Ridulph disappeared from a street corner in her Illinois hometown. She was later found dead — stabbed, stripped, and left under a log miles away. In 2012, a man went to prison for her murder. CNN has a long and well-put-together story about how this killing was solved after so many decades, and the questions people are asking about facts and scenarios that still don't quite add up.
