god. what did i do? and, oh, there s that pillow in her i m going to get rid of that pillow, then the arms are already up. reporter: and you think that s what happened? yes. reporter: but then came, perhaps, the most anticipated testimony for the prosecution. lyndsay, curtis own daughter, took the stand. two times, over a span of eight years, she told police her mother was alive that morning. she said she had felt better. reporter: but on the stand, with her dad s life on the line, she changed her story. telling jurors she was no longer sure her mom was alive that day. don t remember any of it. reporter: but it doesn t stick in your memory? nope. reporter: and yet, detective baird s notes, you do tell him the story about seeing your mother. and then with the videotaped interview with detective gibson, you seem quite clear about that morning, and yes, you saw her and went off to school. what had happened in the interim between your statement and going into tria
remembers seeing her mom alive, but then she backs away from it and says, i think i can t remember really. i don t know what s in lyndsay s head and in her heart. one day she was happy and then everything changed. reporter: the prosecution still had to explain why the two oldest boys were adamant their mom was alive that morning. parkinson told jurors there was a two-day gap between cory s death and the first police interviews with the kids. ample time he suggested, for the boys to be influenced by their dad. i think the children were confused as to which day. after all reporter: how about coached? do you think that he told him a story? he had custody of the children from the moment of her discovery until thursday afternoon. so from tuesday till thursday afternoon, i don t know what was said. reporter: dr. jane turner, the pathologist detective gibson hired to review the case, took the stand and said science is where the truth lies. she concluded the most reasonable e
how was your parents relationship, do you remember? they would fight. it was an interesting relationship. there were times we were like the perfect family, we d do like fun family stuff. and then there were times i do remember being woken up at night by my parents fighting. reporter: for the first time, someone inside the lovelace family was revealing the turmoil before cory s death. but then the detective asked lyndsay to describe that tuesday in 2006 when her mother s body was found. tuesday morning, before you went to school, what do you remember? the answer seemed to take the air out of his theory of the case. she was up and walking around she had made breakfast. i don t remember what we had for breakfast. but she had like made us breakfast and she was helping us get ready for school because we all had our little valentines day boxes. the young woman candid about her parent s troubled marriage was nonetheless supportive of her father s account. cory ha died minu
he told me everything would be okay. and that we were gonna have to to fight some things. reporter: christine was a wreck. her husband was in jail and she was dumbfounded as to why the police had taken the boys out of school and then interviewed them without parental permission. she felt better about this though the two oldest boys backed their dad s story they had seen their mom cory alive valentine s day morning, just like curtis said. they saw their mother alive that day. the and that s that s the gist of their story. yes, i saw her alive that morning yes. when dad took us to school. uh-huh. so there it was valentine s day. so therefore she couldn t have been dead upstairs and right. dying and rigor mortis setting in. right. because we saw her alive. uh-huh yes. reporter: the boys sister lyndsay, had also told police two separate times her mom was alive that morning, had seen her off to school on valentine s day. she was standing in t
courtroom. it s clear to me it didn t matter what i did. as far as the prosecution was concerned. their only concern was that they needed to create a crime and they needed for me to look bad in order to do that. reporter: curtis didn t necessarily need prosecutors help to look bad. some of his own actions the day cory died were at the very at least unusual. including never calling 911. reporter: he called who? his boss. reporter: his wife is dead in the bed? yes. reporter: and he calls his boss? yeah. and said, my wife is dead. so his boss, said, well, would you like me to call the ambulance people? yes. would you do that? reporter: cory s mom, marty didriksen, who lived just a few houses away, testified that curtis broke the news of her daughter s death in what she thought was the most callous way. there was a knock at her door and curtis was standing there with 4-year-old larson. i open the door and he hands me larson. reporter: and says? oh, and
