In the summer of 1978, a mother and her four-year-old were stabbed to death in the quiet town of New Castle.
A series of intense trials ensued as Costal was convicted of the homicide.
Sitting in a Lawrence County jail in 1981, convicted serial killer Michael Atkinson accused Frank Costal--a carny, petty thief and Satanist--of having an affair with the Kadunce husband and participating in the murder.
Police suspected the husband, Lou Kadunce, but were unable to find either a weapon or a motive.
