True Crime author, Diane Fanning, had several communications with serial killer Tommy Lynn Sells. Through that correspondence Sells confessed to the murder of a little boy whose mother had been convicted and sentenced for his death. Through the evidence and statements collected, her testimony was instrumental in setting free an innocent woman. She writes about the case in her book Through the Window.  Fanning says Sells went through his religious “phase” in prison, but it didn’t last. Why?
