>> the day after the jack jessee murder, a guy walked into a bar, sat down on the barstool, and told the bartender a story about how the murder happened, about who did it, about what the motive was. the whole story. but of course that was just a story in a bar. detective wyatt didn't hear anything about it. and as he continued to dig for clues he hit an unexpected wall. sandra announced she had now helped as much as she could. she was done. >> i was referred to her attorney and she refused to meet with us again. >> reporter: same thing happened with sandra's kids, jack's stepchildren. while jack's blood relations practically begged to help solve the case. so what happened to that big happy family in the video? a mirage, perhaps? in fact, living with sandra, said jack's daughter cheree and cheryl, was a fairy tale, the kind britain by the brothers grimm. >> she was mean to me. she wanted me completely gone. she did everything she could to try and get rid of me. >> reporter: when it came to her own children, they said, sandra was indulgent, eerily so with son tom.
