BETHEL, Conn. (AP) — A 46-year-old Connecticut man and his 23-year-old daughter told police they weren’t certain they were related before beginning a sexual relationship and having a son together, police said in charging them with sex crimes.

George Sayers Jr. and Tiffany Hartford, of Bethel in western Connecticut, were charged Monday with third-degree sexual assault, obscenity and conspiracy after authorities said DNA tests showed Sayers was the father of both Hartford and her baby. Each pleaded not guilty and was being held on bail.
