Welcome to Dateline True Crime Weekly. I'm Andrea Canning. It's September 10th, and here's what's on our docket.

In Florida, the trial of a 16-year-old accused of murdering his step-sister on a cruise ship is delayed, for a surprising reason.

Jesse Kirsch (0:35)

You might think, oh, maybe that's a stall tactic, but here's the explanation.

Andrea Canning (0:39)

In Dateline Round Up, we've got the latest on the Texas man who fled to Italy on the eve of his murder trial. And Barry Morphew, the Colorado husband accused of killing his wife with an animal tranquilizer, is back in court.

Rachel White (0:51)

So Barry was arrested last week, and according to a court filing, he was involved in a hit and run crash.

Andrea Canning (0:58)

Plus, the insanity defense. We heard a lot about it at Lindsay Clancy's trial, but how often is it actually used?

Danny Cevallos (1:05)

When these cases come up, it becomes a battle of the experts.

Andrea Canning (1:08)

Before all that, we're heading back to Massachusetts for an update on the explosive final hours of the Clancy trial and where the case goes from here.

Last week, a jury of nine women and three men entered their seventh day of deliberations in a case that has transfixed the nation. Lindsay Clancy, the 36-year-old mother and former labor and delivery nurse accused of murdering her three young children.

Prosecutors urged the jury to find Lindsay guilty, saying she deliberately planned the children's deaths. Lindsay's defense argued she was not in her right mind, struggling with postpartum psychosis and a cocktail of medications. Twice, the jury told the judge they were deadlocked. Twice, he sent them back to try to find common ground. Then, on Friday morning, just after 11 a.m., the jury came back with a note that kicked off an extraordinary series of events. Our own Blaine Alexander was there for it all, and is here now to fill us in on the drama inside the courtroom. What jurors have since revealed about their deliberations and what could happen next. Blaine, thanks for being here.

Blaine Alexander (2:14)

Andrea, thanks so much for having me.

Andrea Canning (2:16)

So as we said, Blaine, we were at the Plymouth County Courthouse for the final week of trial. What was it like reporting from there? Set the scene for us.

Blaine Alexander (2:25)

You know, Andrea, I can't overstate for you just how many, you know, of course, traditional media, but just bloggers, people who were streaming, how many people were at that courthouse trying to capture every single moment of what was happening.

Andrea Canning (2:38)

Yeah, it seems like you can't click on social media or, you know, a news website and not see the Lindsay Clancy trial. It has gotten so much attention, Blaine.

Blaine Alexander (2:48)

You're absolutely right, Andrea, and not just from the people, of course, who were there in Plymouth, but there have been people who have really felt some sort of connection to this case. In fact, Lindsay Clancy's attorney, her defense attorney, Kevin Reddington, actually came in holding what he said was a box of letters from people who had just written to her over the course of this trial wanting to show their support.

Andrea Canning (3:07)

Yeah, she definitely has a lot of support, and then there's people that don't support her.

Blaine Alexander (3:12)

That's right. In addition to the supporters and the people, of course, who go the other way, there have been a lot of conspiracy theories flying around about this case, specifically about the role that her husband, Patrick, played in all of this. And so that really has added to just so much of the chatter here in all of this.

Andrea Canning (3:27)

One of the theories is that Patrick might be responsible for the children's deaths. And we just want to say that he has never been accused of anything by law enforcement or prosecutors.

Blaine Alexander (3:37)

Absolutely. And not only has he not been accused of anything, but Lindsay Clancy herself and her defense attorney have not disputed the fact that she in fact killed her children.

Andrea Canning (3:45)

And that's what's making some of these conspiracy theories seem so outlandish. Yes. Because of her confession that she killed the children.
