ABC NEWS EXCLUSIVE

Stunning new details about the deadlock jury that after seven days of deliberations could not unanimously decide whether to hold Lindsay Clancy responsible for killing her children. I think we felt defeated. You wanted to come to a conclusion. Right. And you spent seven weeks, you know, all of our lives dedicated to it. On this trial, almost two months. Of our lives. At first, Nick Dargie, juror number 10, told us several jurors lean toward a guilty verdict, but eventually, there was just one holdout who he said expressed doubt about the case, but voted to convict Clancy anyway. It was definitely frustrating, mainly when he, uh, explicitly said, you know, I don't know if the prosecution or the defense proved their case. He expressed that. Take me inside the deliberation room. There were times where, uh, our vote was different than the last day. But I think ultimately, once we laid out all the evidence and how we saw it, that really brought everyone kind of on the same page except for this one juror. There were several times that I would ask him to show us, like, evidence or, you know, describe a witness testimony that helped to prove their case, and he couldn't. And he couldn't. There is nothing wrong with somebody having a completely opposite opinion, like that, you know, that is our justice system. But he wouldn't engage or couldn't find something to support his view. There were times he wouldn't engage, like, he'd be scrolling on his phone while people are talking to him, while people are talking to him, you know, things like that. Darji told us one time he confronted the holdout after the deliberation. He picked up what Clancy used to strangle her kids, an exercise band out of the bag and tied the band around the water bottle and pulled it. Did he explain why he did that? No. I, I assume so, yeah. Was that a mimic of how she killed the children? Yeah. I assume so, yeah. What did you think when he did that? I was shocked. It didn't make any sense to me. We're not in here to play detective or, you know, it's serious. I asked him, why are you doing that? That's a band that was used to strangle a child. It's disgusting. Darji is 25. He was serving in the military overseas and knew nothing about the case before he was picked as a juror. Now he says it haunts him. I can't close my eyes without imagining his kids, you know, sitting through all that evidence, sitting through all that witness testimony that helped to prove their case, and he couldn't. And he couldn't. I thought she was not guilty by reason of insanity. No doubt in my mind. No doubt. I think if they tried the trial again, the way they did, I think nine times out of 10, a juror would come back not guilty by reason of insanity. And the mis trial. The state has to decide whether to put her on trial again. What do you think? I think if they tried the trial again, the way they did, I think nine times out of 10, a jury would come back not guilty by reason of insanity. He also heard the bloodcurdling call Patrick Clancy 911 one when he discovered his children. So harrowing, the judge refused to release it. Darji said it's seared into his memory. I'll never forget that. That was frightening. I've never heard something like that scream like that come out of someone's mouth. Patrick Clancy. Right. You know now. That the internet is a wash in theories that he had something to do with the deaths of his kids. I don't believe in that. I don't believe that he was the one who did it. I think if everyone heard that 911 call, they would change their mind. If prosecutors decide to retry Clancy, a new jury would have to hear it all again. As a result of the deadlock and the mistrial. Aaron Katersky speaks with Nick Dargie, one of the three male jurors in the Lindsay Clancy trial, as he describes the tense deliberations and deadlock that led to a mistrial. He said he found the prosecution's case inconsistent. The defense experts more believable. And he said he was moved by Susan Clancy's testimony, standing by her daughter-in-law.
