cards was going to collapse in trial. reporter: in october, 2016, more than two years after the death of his son, ross harris went on trial for murder. death. deception. and a double life. reporter: chuck boring, the lead prosecutor, told the jury why ross story had never added up. that chick-fil-a video showed cooper wide awake. that drive that was too short to forget a toddler. the car seat was just inches behind ross. and at ross office there was a photo of cooper and a gift from cooper. he even sent a text to leanna in the afternoon about cooper. when you getting my buddy, it said. none of that jogged his memory? there was just cue after cue after cue that if he had actually forgotten would have triggered something. reporter: and then the prosecution showed what it believed was powerful evidence that ross had to have known that cooper was still in the backseat.
because she believes 100% that it was not intentional. reporter: so there she was in court, not condemning ross, but defending him. tell these folks a little about cooper. cooper was the sweetest little boy. he had so much life in him. he was everything to me. reporter: and everything to ross, too, she testified, as the jury watched family videos of father and son. what are we looking at there, leanna? that s just them in the bed. and that s just kind of a little game that they would play. reporter: leanna said ross was the kind of dad who always played at the park. go. reporter: and made goofy
reporter: having seen the appeal, vic reynolds, the top prosecutor in cobb county believes it won t change the outcome. i have complete confidence in the jury s verdict, complete confidence in the evidence that was presented, and i believe when the day comes, this verdict will, in fact, be affirmed. reporter: but ross harris supporters say there is another tragedy in all this. they believe his conviction will make things worse for parents who make similar, terrible mistakes. this sets the precedent that anyone that does this is a monster. and that s just not the case. this really can happen to anyone. reporter: cooper s family may never stop grieving for the little boy who had just learned to say his dad s name, loved his trucks and loved to smile. what does leanna want cooper s legacy to be? that he was loved. he was very loved by everyone
left him in the car. reporter: it made sense because she knew ross so well. he could be forgetful. and when she saw the video of him with police, she recognized that ross, too. this morning we woke up reporter: the overly-social guy just chatting away. he just would talk to everybody, very outgoing, very vocal. he didn t he never met a stranger. reporter: but leanna also told the jury how ross looked when she first saw him at the police station. she says he was in terrible pain. it was very difficult to see him like that. reporter: this was the true face of ross grief and guilt, the defense said. and leanna explained to the jury why she asked ross that question that made investigators so suspicious. did you say too much?
