there is sparking unrest throughout the country, in the road. they re more than 900 people were arrested. for now, back to dateline! were arrested. the investigation was, literally, closer to home now. that is to say that the detectives investigating the murder of nancy began looking at anybody who had access without permission, to nancy ncyeah but they had to start somewhere. mr. styler s an anesthesiologist. mrs. styler, from all accounts, was an intelligent woman herself. keith morrison: trey and nancy met in the anesthesiology department at a denver hospital, he, a resident, and she, an instructor. nancy styler: i heard him go up to a woman on a gurney and say, hello, i m dr. styler. i ll take care of you as though i were taking care of my mother, and i love my mother.
and if it wasn t nancy, couldn t have been trey either. because he was frail, yes, said, nancy, but also because he was never alone to do it. you were never without him. you were always together. yeah, i said we were always together. keith morrison: what did make sense, said attorney krulewitch, is that someone else killed nancy pfister and planted the evidence against the stylers in an attempt to frame them. the final piece of it was that the owner s closet key magically appears on the sidewalk near the stylers motel room the day they get arrested. keith morrison: it was a thought that crossed investigators minds as well. lisa miller: we would have been amiss had we not looked at the possibility that someone was setting these people up. keith morrison: and so even with the stylers in jail, charged with murder, investigators were still quietly looking for other suspects, for someone with motive and means to kill nancy and the foresight to frame the stylers, someone close to nancy,
why? well, the trash bag containing so much incriminating evidence, for example, the one the diligent city worker just happened to stumble on i really think that this was actually pure luck. i don t think anyone wanted that to be found. i think, really, the simple explanation here is really the right explanation, which is that we had a great break in the case and thank goodness for that. keith morrison: the only conspiracy theory assistant da andrea bryan was buying was one that involved the stylers and kathy carpenter, all of them together committing the murder, the two women perhaps bonding over their shared frustration with nancy pfister s behaviors. it appears that they almost built, at times, a bit of a friendship around that mutual anger toward nancy pfister. keith morrison: and trey, pushed to his financial and emotional limits, was most likely the one to wield the hammer, reasoned the assistant da, while the women helped hide the body and clean up the bedroom.
keith morrison: and then, it was just over two weeks later, nancy took a call. trey had something to tell her. his letter wasn t quite true, he said. in fact, he and he alone murdered nancy pfister. kathy carpenter had nothing to do with it. it was took my world and just flipped it upside down. felt like my whole life had been a lie. my whole life with him had been a lie. so what did he say about being able to withhold that information from you? i said to him, why didn t you tell me, why didn t you tell me. and he said, i was able to tuck it in a small part of my brain where i tried to admit that it wasn t there. and i said, because if you had told me, i would have brought you down to the police station and said, he needs help. give this man the help he needs. and can you imagine that i slept next to him
