at the sheriff s office, investigative supervisor tavizon questioned his deputy, sanchez. why hadn t he even dusted for fingerprints? he said, no, he said, it s too clean. to him it wasn t anything that would ve been helpful to the investigation. kind of an assumption there, huh? well, i guess i would that s what you could call it. what s the old expression? to assume makes an ass of you it makes both and me. yeah, exactly. so, with zero physical evidence to point to anyone, the case of the murder in the bathtub went cold. until? until six months later, a particular friend, once suddenly gone, just as suddenly reappeared. time for a pertinent question or two. coming up billy lee back from alaska admitting he and cassy were
detective sanchez claimed by leaving her in the water, it watched any a mint. i thought that she was gonna be dead in the water. we started looking for what happened. there was still water in the drug. we pulled the train and i saw blacks got marks. a case that would see the suspect leave town. and unearthed dark deeds from the past. she would wake up and he was be standing over her. that s creepy. sinister stories! she told me that he was following her. yet justice was anything but certain. you want that smoking gun. uh-huh. and there s just not one. hello and welcome to
what about the polygraph? why that inconclusive result? i can tell you why, instead of you ever been in the house, i said, yes. and she kind of raised her eyebrows because that was our rental house, of course i been in the house, multiple times. maybe they should have asked cassy s family who didn t for a minute suspect billy lee. they would have told the deputies it was long past time to focus on someone new. and who could that be? the person the family had suspected all along. he did it. he killed her. we know he did. coming up disturbing stories about one of the men in cassy s life. she would wake up and he would be in the dark watching over her. then a new theory of the case. he said a cop did this. that this had been done by someone who had been trained in police tactics. when dateline continues.
