Two sisters, 15 year old Barbara and 12 year old Patricia Grimes, disappeared after watching a movie at the Brighton Park Movie Theater in Chicago on December 28, 1956. Less than a month later their nude bodies were found on the side of a highway, covered in snow. There were no fatal wounds to either sister, which baffled investigators. To this day, their murders remain unsolved.
