In the early morning of July 2, 1937, a young woman was found on an open field in Jamaica, South Queensland, United States. Next to the body, there was a little baby girl crying, but she was not hurt. The weapon is a stained concrete that was found not far from the body. At the scene, there was also an electric iron and a man’s shoe, all of them dipped in a pool of blood with a hole in the shoe’s sole.
