the investigators checked off what they had so far. a young woman supposedly drowned in the bathtub with a damp head of hair and a dry body. it didn't figure. >> if you're pulling somebody out of a tub of water, it has to be wet. there's no way around it. >> a woman with unexplained bruises. and a husband whose story they didn't believe. >> ryan's story doesn't fit at all. we determined at that point we had a homicide. >> sarah murdered. and the authorities believed her husband ryan did it. how shocking is that to you? >> oh, i can't even tell you. >> they charge ryan with murder. >> i mean, you've got to be kidding me. like why would they think -- why? and i can't even tell you what that was like. so on top of losing this beautiful member of our family, he didn't even get a chance to grieve because now we're scared to death and he's scared to death that he's going to be charged with murder.
