proof enough that the prosecution s argument didn t hold up. when you walk in the house, there s no way that there s even 12 feet there. reporter: what s more, according to the defense team, conrad never told the police heidy shot herself in the bathroom. instead he told them he had no idea where she was when he heard the shot. tell me your theory of what happened here. we believe that heidy truman shot herself in this very area, and we believe that she fell right in the area directly in front of me on the ground, and that s the very area where she was found when law enforcement entered the home that night. reporter: which they also said was completely consistent with the m.e. s testimony that heidy would have fallen after only a step or two. she would have gone to the ground immediately. reporter: your argument is she did fall down. exactly! reporter: and she fell right about here. yes. that s exactly what our argument is. reporter: according to moffat, this was no
thanks to conrad, heidy had firearms experience. can you think of any way it could have been an accident? no. heidy wouldn t have been so careless. reporter: so what about suicide? she s completely naked. we don t see a lot of women that commit suicide naked. that s not common. reporter: did you find anybody that heidy had spoken to about suicide or about being depressed? no. reporter: neither heidy s mother janet nor her sister autumn could imagine heidy even thinking about taking her own life. heidy would never do that. in fact, heidy was against that. she had a friend who committed suicide, and she thought it was selfish and, in her words, dumb. reporter: heidy ever tell you she was depressed? no. reporter: ever act depressed? no. she was probably one of my happiest, most upbeat kids. reporter: that left wallace with homicide, and it put conrad back in the police crosshairs. wallace decided to speak to the officers first on the scene
gunshot residue on him. conrad s attorneys were working hard to establish reasonable doubt. that s your case right there. you would think. i mean, if he has reasonable doubt, hard to argue a jury shouldn t. exactly. the medical examiner told the jury in the final analysis he didn t know the manner of heidi truman s death. i finalized the autopsy report with the cause of death as a gunshot wound and manner of death as could not be determined. the m.e. also testified how in his experience, a contact wound like heidi s is rare in homicide cases. after 15 days of testimony, the jury began deliberations.
in the process of transposing numbers from actual measurements at the scene to the crime scene program, numbers were just transposed wrong. reporter: wallace admits the error but says it was minor, that conrad truman did not deserve a new trial. it s not that significant as they made it out to be. reporter: did those incorrectly entered measurements change your opinion of conrad truman s guilt? should they change anyone s opinion? they didn t change my opinion. reporter: nor did it change the opinion of the deputy d.a., tim taylor, who decided to take on the task himself of prosecuting conrad once again. i think craig had been into the case for a long time, so i wanted fresh eyes. so i went through all the evidence. and even with the medical examiner changing his opinion, i still felt that there was enough to go forward. but we knew going into it, it was going to be tough. reporter: at trial the prosecution s case was familiar. starting with the officers who testified a
prosecution s case was familiar. starting with the officers who testified about conrad s rambling often incoherent description of what had happened that night. the core of our case were his inconsistent statements. the story was hard to follow. it was jumping around all over. it wasn t making sense to me. so it was hard to follow. reporter: those officers also told the jury about conrad s threats. he was telling us that we were going too slow and we needed to hurry up or he was going to kill us. i ll [ bleep ] kill you if you don t save her life. if you are making these violent threats to people who are there trying to help your wife, how are you treating your wife when it s only you and her alone? reporter: taylor then tackled the theory of suicide by calling witnesses to testify heidy was not suicidal. in your experience as heidy s mother, was she a sad or depressed person? no. i didn t see her that way.
