What is the case of Mark Sievers about?
We'll see you next time. Good morning.
Good morning. You're listening to Dateline's morning meeting.
They then put him under hypnosis. That is also on video.
Our editorial team is catching up on breaking crime news. If she was innocent, what would their motive be? Something to do with him being stabbed. Maybe he stabbed himself.
What new developments are there in the Miami model's murder trial?
It is in the hands of the jury.
Welcome to Dateline True Crime Weekly. I'm Blayne Alexander, filling in today for Andrea Canning. It's October 16th, and here's what's on our docket. In Miami, the case of the model who said she fatally stabbed her boyfriend in self-defense ramps up for trial. Prosecutors say it was murder.
So when police walk in, they find Kalani just cradling her boyfriend. There's blood all around the room.
In Dateline Roundup, a medical examiner weighs in on the mysterious death of a Philadelphia teacher. And Donna Adelson, the Florida grandmother convicted of plotting the murder of her former son-in-law, speaks out at her sentencing.
How did the domestic violence history impact the case of the Miami influencer?
I had no knowledge that this horrible evil act was going to take place.
Plus, a riveting new drama series about the victims of John Wayne Gacy. Andrea interviews the show's creator and cast.
But before all that, we're heading to Florida, where a man sentenced to death for murdering his wife, a doctor, tries to convince a judge he got a raw deal. Ten years ago in sunny Bonita Springs, Florida, Dr. Teresa Seavers was making a name for herself in the field of holistic medicine, appearing on local TV shows and speaking at public events.
Getting you healthy is my passion.
Being healthy is your choice. When the devoted doctor didn't show up for work on June 28, 2015, Her patients and her staff immediately knew something was wrong. Her husband, Mark, who was out of town, asked a friend to check on her at their home, and what that friend found was a bloody crime scene.
What evidence challenges the self-defense claim in the influencer's case?
911, what is your emergency?
I'm at a friend's house, and I came here to check on his wife, and she's dead on the floor.
Teresa had been bludgeoned to death. Investigators quickly zeroed in on a suspect, Teresa's husband, accusing him of hiring his best friend and another man to commit the crime. In December of 2019, a jury convicted Mark of murder and he was sentenced to death. This week, more than a decade after Teresa's death, Mark is once again standing before a judge. He says he's innocent and that his case needs a second look. There is a lot to cover here, and there's nobody better to break it all down than my good friend Dennis Murphy, who has covered this case extensively for Dateline. So, Dennis, thank you so much for being here today.
Always a pleasure to be with you, Payne.
What are the details surrounding Donna Adelson's sentencing?
So let's start by talking about Dr. Seavers. She's this beloved doctor. Her husband was out of town at the time. How did he react to learning this tragic news?
Well, it's not just a rule on Dateline 101. It's also a law enforcement 101 that the spouse is always a suspect until he's not. Now, Mark Seaver's alibi was that he was a three-hour plane ride away. He was up in Connecticut visiting with family. So he couldn't have been in the house, but he flew back down that day and was soon in a police interview room where things got really interesting.
Tell me more about that because I know that you have said that this was one of the more memorable interrogations on Dateline.
How are John Wayne Gacy's victims portrayed in the new mini-series?
People say you never know how anyone's going to react to a situation. But in this interview room, he's crying. He's hitting himself. He's scratching. She had so much to offer the world. She was really – everyone says this about their wife. Their kids are special. My kids are phenomenal. Sure.
She really is on track to change the world.
What insights does the cast share about the Gacy series?
Breathe. Breathe with me.
Slow me down. My wife is so much better at this than I am. And then the police leave the room, but they can still hear Mark talking on the recording, apparently to Teresa. Oh my God, Teresa.
What could I have done if I was with you? This wouldn't have happened if I came back. This wouldn't have happened.
And then afterwards, once he kind of calms down, what does he tell police?
