both were former students in tara's history class. >> why would ryan duke have murdered tara grinsteadryan and he know. >> i knew that he probably would have served the rest of his life in jail, but that family's peace to me was more important than his freedom. >> that's when brooke went to authorities, telling them she knew what happened to tara grinstead and where her remains could be found. then she confronted beau. >> i said you need to confess, own confess, i said, because ha family deserves to know. >> what does beau say. >> he says i just want her family to know. >> ryan duke was arrested and charged with murder. beau dukes who is not related was charged with concealing her death and is expected to be the star witness against ryan. >> so did he confess and is she still with him, that's what i want to know. >> beau did confess. he told his deep dark secret and that led to ryan's arrest, and, yes, they are still together. brooke who is a pharmacist, very bright woman loves him and is proud of him for coming forward after all of these years to help solve this crime. >> thanks, pete
