[01:56 – 10:54]

Background

• Kouri Richins, author of a children’s book on grief, stands accused of poisoning her husband Eric Richins with fentanyl to access insurance money and pay off debt
• The third week of trial featured the headline testimony of her ex-lover, Robert Josh Grossman

Key Moments & Testimony

• Josh Grossman’s Hesitant Swear-In [03:24]: Emotional tension as Grossman hesitated before taking the oath, causing the judge to dismiss the jury and clarify his willingness to testify
  • Quote [03:48]:
    Judge: "Do you promise ... to tell the truth when you're asked questions?"
    Josh Grossman: "Absolutely."
• Relationship Backstory [04:05]: Grossman met Kouri through a house flipping ad in South Carolina. Their affair turned romantic in 2020 as he moved to Utah to support her business.
  • Quote [04:31]:
    Lester Holt: "Did you feel that she loved you?"
    Josh Grossman: "Yeah, yeah ... I have a tendency of going head over heels though, probably more than most. So, you know, I think she did."
• Text Message Evidence [05:08]: Jurors read intimate exchanges projecting the evolution of their relationship. Grossman became visibly overwhelmed, sighing and muttering.
  • Quote [05:53]:
    Josh Grossman: "Man, man, oh boy, oh man."
• Content of Texts [06:02]:
  • Kouri confided ambitions ("One day I’ll own properties in Park City") and fantasized about a future with Grossman, including marriage, wealth, and a farm
  • Notable February 15, 2022 text:
    Kouri: "Like, actually in love with me. If I was divorced right now and I asked you to marry me tomorrow, you would?"

Summary

Grossman’s testimony humanized the prosecution’s narrative, showing a relationship fueled more by escapism than active plotting. His pain and surprise were palpable, reinforcing the prosecution’s theory of motive while the defense leaned on his professed ignorance of any murder plot.

Jared Brightigan Murder Case: A Prosecutorial Setback

[12:46 – 20:30]

Case Recap

• Jared Brightigan, a Microsoft employee, was shot and killed in Jacksonville Beach, Florida, with his daughter in the car
• The gunman, Henry Tennant, confessed, implicating Jared’s ex-wife Shanna Gardner and her new husband, Mario Fernandez Saldana
• Recent developments threaten to derail the prosecution’s case

Key Discussion Points

• Investigative Breakthrough [14:56]:
  • Tennant, a tenant at a property owned by Gardner/Saldana, was connected via a tire and a matching blue Ford truck from the scene; payments from Saldana further linked them
• Motive [15:55]:
  • Motive cited as ongoing custody battles and a trust fund; text messages indicated hostility ("I want them gone") and coded language (‘magician’, ‘funeral potatoes’)
• Doubt on Testimony [18:16]:
  • Kim Jensen, a friend, doubted both Shanna's familiarity with Tennant and Mario's choice of Tennant as an accomplice
  • Quote [18:16]:
    Kim Jensen: "If Mario did this, you’d have called one of your military sniper buddies."
• Plea Withdrawal [18:39]:
  • Tennant withdrew his guilty plea and refused to cooperate, providing a lifeline to Saldana’s defense
• Implications [19:16]:
  • Defense argued lack of physical evidence against Saldana and legitimate payments to Tennant
  • Quote [20:06]:
    Defense: "No DNA of Mr. Fernandez was found inside the blue Ford 150 ... There is no follow the money."
• Gardner’s Position [20:30]:
  • Her defense closely watched these developments, likely to seek similar relief if Saldana is granted bond

Summary

The case highlights the fragility of prosecutions relying on one key witness. With Tennant out, the charges against Saldana—and by extension Gardner—face new hurdles, especially on evidence linking them to the murder.

[Lester Holt]

Hi, everyone. Hi. You're listening to the DATELINE Morning Meeting. Detectives, they start having questions.

[DATELINE Producer Mike Nardi]

They're suspicious.

[Lester Holt]

Our producers are catching up on breaking crime news.

[DATELINE Producer Karen Israel]

There's some question whether the girlfriend, you know, will she flip? Just a lot of hazmat people in a nice neighborhood.

[Lester Holt]

Welcome to DATELINE True Crime Weekly. I'm LESTER HOLT. It's March 12, and here's what's on our docket. Three years after the ex wife of a Microsoft employee is arrested for allegedly plotting his murder, the prosecution's star witness surprises everybody.

[VRBO/Amica Insurance/Lemonade Pet Insurance Announcer]

He doesn't want to testify, dealing a potential blow to the prosecution in this case.

[Lester Holt]

In DATELINE Roundup, we've got a verdict in the murder trial of Michigan farmer Dale Warner and the latest on a new filing in the case of alleged Gilgo beach serial killer Rex Heuermann.

[DATELINE Producer Mario Garcia]

According to this latest filing, investigators discovered that Heuermann contacted sex workers over some 500 times.

[Lester Holt]

Plus, Josh Mankiewicz will be here to tell us about his latest podcast series, Trace of Suspicion.

[Josh Mankiewicz]

The question that I want people to think about at the end is what constitutes justice?

[Lester Holt]

Before all that, we're headed to a Utah courtroom where emotions are running high at the trial of Corey Richins, the author of a children's book on grief who has been accused of plotting to murder her husband. It's week three in the trial of a Utah widow who prosecutors say poisoned her husband with a lethal dose of fentanyl so she could cash in on his life insurance and pay off a mountain of debt. On last week on the show, we talked about how prosecutors allege Cory Richards got her hands on the fentanyl that killed Eric Richards. Since then, the jury has heard from witness after witness about why Corey wanted him dead, ranging from a forensic accountant who mapped out how much debt she was in to a friend who said Corey told her she could only see one solution to her Problems.

[DATELINE Producer Karen Israel]

She said that in many ways, it

[VRBO/Amica Insurance/Lemonade Pet Insurance Announcer]

would be better if he were dead.

[Lester Holt]

But the witness who got everyone's attention was a man the jury has been hearing about since day one of the trial. The man prosecutors say Corey wanted to start life over with her lover, Robert Josh Grossman. And for two hours, Josh Grossman wept, groaned and sighed as prosecutors dissected the affair for the jury. My next guest, DATELINE producer Karen Israel, watched it all and is here to talk us through it. Karen, welcome back.

[DATELINE Producer Karen Israel]

Thanks for having me.

[Lester Holt]

Karen. This was a big moment. This jury was ready to hear from him.

[DATELINE Producer Karen Israel]

It sure was. And there was some drama when he walked in. He didn't take the stand right away. The clerk started to administer the oath, but Josh seemed to hesitate. So then the judge got involved, dismissed the jurors, and asked Josh on the stand whether he'd tell the truth.

[Josh Mankiewicz]

Do you promise under the pains and penalties of perjury to tell the truth

[Lester Holt]

when you're asked questions?

[Josh Grossman]

Absolutely.

[DATELINE Producer Karen Israel]

There was a bit of a rocky beginning to his testimony and maybe hinted at just how nervous he was.

[Lester Holt]

Yeah, I've never seen a case where the issue is over the simple swearing in of a witness. So the prosecutors asked him to explain how he and Corey met. What did he say?

[DATELINE Producer Karen Israel]

Josh told the jury that he and Corey met in South Carolina when he responded to a help wanted ad for a house that she was flipping. And in 2020, just before he moved to Utah to keep supporting her home flipping business, he said their relationship turned romantic.

[Lester Holt]

During that time that you were romantically involved with Ms. Richards, did you love her?

[Josh Grossman]

Yes. During that time, did you feel that she loved you? Yeah, yeah, Yeah. I have a tendency of going head over heels, though, probably more than most. So, you know, I think she did.

[Lester Holt]

Did you exchange text messages with Corey Richards?

[Josh Grossman]

Yes.

[Lester Holt]

From the time you moved to Utah, about how often?

[Josh Grossman]

Daily. Unless she was mad at me or vice versa.

[DATELINE Producer Karen Israel]

It was at that point prosecutors began asking Josh to identify text messages he and Cory exchanged.

[Lester Holt]

Do you recognize this as a text,

[Josh Grossman]

As a text exchange that you had with Ms. Richins? I got you, and I do for this one.

[DATELINE Producer Karen Israel]

And then the texts were shown to the jury.

[Lester Holt]

Karen, instead of having Josh read the text aloud, they were projected onto a big screen for jurors to read for themselves. We're talking about dozens of texts here. And Josh got pretty emotional.

[DATELINE Producer Karen Israel]

He really did. It was a bit of a strange situation where the courtroom was completely quiet and everyone's reading these intimate texts to themselves. And then you'd hear him muttering under his breath.

[Josh Grossman]

Man, man, oh boy, oh man.

[Lester Holt]

What was the content of the text?

[DATELINE Producer Karen Israel]

We really saw their relationship unfolding. Corey was opening up to him, which I found really fascinating. We've heard from the prosecution about her being motivated by money. She opened up to Josh about how she grew up scrubbing other people's toilets in Park City and felt looked down upon. And she wrote that one day I'll own properties in Park City like all these rich, snooty people. You also see the relationship get more and more serious. For example, in one message on February 15, 2022, Corey texted, like, actually in love with me. If I was divorced right now and I asked you to marry me tomorrow, you would. Josh wrote back, yes, in love with Y O, U. Of course I would.

[Lester Holt]

And Josh was finding it hard to keep his composure.

[DATELINE Producer Karen Israel]

Yes. He started to cry. The judge asked if he needed a break.

[Josh Mankiewicz]

Mr. Grossman, lovely thing.

[Lester Holt]

Do you need a minute or two?

[Josh Grossman]

I don't know what I mean.

[Lester Holt]

Let's just start with that. Why don't we take a five.

[Josh Mankiewicz]

Pause for a moment, if you don't mind. Let's take a five minute break. Please. Please rise.

[Lester Holt]

For the jury, the timing of the messages is important to prove the prosecutor's alleged motives. Some of the ones the jury saw were set in the weeks and days before Eric's death. How would you characterize Corey and Josh's relationship at that moment in time?

[DATELINE Producer Karen Israel]

They were writing back and forth, imagining their future together, but it was almost like a fantasy. In one text, Corey told Josh about a crazy dream she has that Josh will quit his job, Corey will divorce Eric, and she'll come into millions of dollars before they'll move in together, raising kids, even having a little farm. In response, Josh wrote, I'm definitely digging some slash all of that. She admits in another text that the dream is not possible, but it's fun to dream. But these messages, they're not super concrete plans, rather just details of this fantasy life they could have together.

[Lester Holt]

After Eric died, when was the next time that Josh saw Corey?

[DATELINE Producer Karen Israel]

He said it was about two weeks after he died. The two of them drove up to the Uinta Mountains together and talked about Eric's death.

[Josh Grossman]

You know, we sat there and talked for quite a while, you know, and I had never seen her that way. Obviously it was a heavy conversation. And I'm not used to that with her.

[DATELINE Producer Karen Israel]

In this conversation, Josh said Corey had a question for him about his time serving in the military in Iraq.

[Lester Holt]

What, sir? What, sir, did she ask?

[Josh Grossman]

She asked if. If I had ever killed anybody.

[Lester Holt]

Did she ask a follow up question? Yes, sir. What was that follow up question?

[Josh Grossman]

She asked me how it made me feel or something along those lines. And then I answered her. I took it as not out of the normal though. Really?

[Lester Holt]

It sounds like the question didn't make him suspicious or think that Cory had anything to do with Eric's death.

[DATELINE Producer Karen Israel]

From his testimony, no. That conversation didn't raise any big alarm bells. In fact, he told the jury their relationship continued.

[Lester Holt]

Did you and Corey Richards stay romantically involved after Eric Richards death? Yes. For how long?

[Josh Grossman]

I. You'd have to look at my phones to tell me that. I'm gonna guess six months, maybe eight, ten. Best guess. And then what happened? I don't know. Just had a falling out, disagreements thing, you know. Things changed after Eric passed. I mean, I don't know what to say. Things weren't the same. So I don't know if that led to us parting ways or what. But there was a lot on both of us, you know what I mean? Understand?

[Lester Holt]

How did the defense handle Josh on cross?

[DATELINE Producer Karen Israel]

The defense really leaned into him having no idea Corey was involved in Eric's death. The defense also asked about when he found out that Corey was arrested for Eric's murder and how he felt learning this.

[Josh Grossman]

Never, never for a moment did I have a clue, a hint, not a fleeting thought that something intentionally might have happened to him.

[Lester Holt]

Josh testified for two hours before being released from the stand. The state is winding down their case and the defense will have their turn next. What are you expecting to see?

[DATELINE Producer Karen Israel]

We'll likely hear from some of Corey's friends and family.

[Lester Holt]

All right, we'll cover that on the show next week. Thanks for being here.

[DATELINE Producer Karen Israel]

Thank you for having having me.

[Lester Holt]

[Lester Holt]

For our next story, we're heading to a stretch of road in Jacksonville Beach, Florida in February, 2022. Jared Brightigan was driving with his 2 year old daughter in the backseat when he spotted a tire blocking the road. He got out to take a closer look. Seconds later, gunshots rang out.

[VRBO/Amica Insurance/Lemonade Pet Insurance Announcer]

There's a guy in the middle of the road. Like the car is open and he's

[DATELINE Producer Karen Israel]

laying on the ground and he has

[VRBO/Amica Insurance/Lemonade Pet Insurance Announcer]

a little kid in the car.

[Lester Holt]

Jared's daughter survived, but the 33 year old Microsoft employee and father of four was dead. After a year long investigation, detectives zeroed in on the man they say was the gunman, someone who had never met Jared Bright again but ended up telling investigators he'd been hired to kill him by a man who knew Jared very well. The husband of Jared's ex wife, Mario Fernandez Saldana and Jared's ex, Shanna Gardner were both charged with first degree murder and sent to go on trial in a few months time with the alleged gunman on the prosecution's witness list. But then in a recent head snapping development, he changed his mind, potentially upending the prosecution's case. DATELINE producer Mike Nardi was in a Florida courtroom last week to get up to speed. He's here now to tell us what he learned. Hi, Mike.

[DATELINE Producer Mike Nardi]

Hi, Lester. Thanks for having me.

[Lester Holt]

All right. Well, first off, give us a sketch, if you will, of the family dynamics here. What was the state of Jared and Shanna's relationship, at least to someone looking from the outside? At the time of the murder?

[DATELINE Producer Mike Nardi]

At the time of the murder, Jared and Shanna had gone through a bitter divorce but were co parenting their nine year old twins. Jared, like Shanna, had remarried and he had two more children with his new wife Kirsten. So the night he was killed, he had just dropped the twins off at Shanna's house after taking them to dinner. And he was taking his other daughter home when he was ambushed.

[Lester Holt]

The accused gunman was arrested back in January 2023. He was a man by the name of Henry tennant and was a complete str. Stranger to Jared. How did investigators even connect him to the murder?

[DATELINE Producer Mike Nardi]

You know, it's actually an example of good old fashioned police work. So as in any case like this, the detectives had to look at the ex wife and her new husband. So detectives went to a rental property the couple owned to interview the tenants. And one of those tenants was Henry tennant. What's incredible is, while they're interviewing Tennant, they notice a tire outside that appears similar to the tire found at the crime scene. Tenen lets them take the tire, and they learn it was from the same facility as the tire from the scene. And more importantly, they learn Tennon drove a blue Ford truck that matched the truck seen on security footage near the crime scene around the time of the murder. But the real clincher, according to prosecutors, was a money trail tying Henry Tenon to Shanna Gardner's new husband, Mario Fernandez.

[Lester Holt]

Mario Fernandez was arrested a few months after 10, and it took seven months for the police to arrest Shanna. What do prosecutors say was the motive here?

[DATELINE Producer Mike Nardi]

Prosecutors say Shanna had shown deep hostility towards Jared Even years before the murder, as can be seen in text messages she exchanged with one of her friends, Kim Jensen, all the way back in 2015. The friends appear to be speaking in code, Looking for a magician to make someone disappear. And they use stupid as a nickname for Jared. And they even talked about funeral potatoes, and Shanna directly said, I want them gone.

[Lester Holt]

Hold on a second. Funeral potato. What's that?

[DATELINE Producer Mike Nardi]

That seems to be an inside joke, you know, alluding to this idea that when someone dies, it would be common to bring food like a casserole to the grieving family.

[Lester Holt]

So, Mike, I'm curious, if they're already divorced, why would she want her husband dead?

[DATELINE Producer Mike Nardi]

Well, I think the motive is being argued, or will be argued, in sort of two parts. Which is? First, despite a divorce settlement and custody agreement, Shanna and Jarrett seemed to bicker constantly over the care of the twins. So there was a lot of acrimony there. And Shanna's parents are very, very wealthy, and they had established a trust for her. The view from Shanna's family, it appears, was that Jared was after that money. So there was language in the trust that Shanna could not control it until she had no Further entanglements with Jared. So money and rage. Sort of pretty common motives for murder.

[Lester Holt]

Yeah. So that sounds like, as you say, a strong motive for murder. But there's no evidence of any kind of communication tying Shanna directly to Tennant. She's denied having anything to do with the murder. Do we know if she ever met Tennant?

[DATELINE Producer Mike Nardi]

Police asked Shanna's friend Kim Jensen that question in an interview shortly after Tennant's arrest. Prosecutors just released video of that interview. So we can take a listen to what she had to say.

[Josh Mankiewicz]

Do you know if she ever met him? I know.

[Josh Grossman]

And the only reason I asked that

[Josh Mankiewicz]

is because I guess he was living in Mario's property for a while.

[VRBO/Amica Insurance/Lemonade Pet Insurance Announcer]

I do not believe so, because I know that his. I don't know who, but I know that at least one of his tenants are smokers and she's allergic to smoke.

[DATELINE Producer Mike Nardi]

In her interview, Jensen seemed skeptical that Mario would have hired Tenen as well. She told police she didn't think Tannen would have been his pick for a partner in crime. Mario was ex military, and Jensen said if he'd really wanted to kill someone, he'd have found someone better.

[VRBO/Amica Insurance/Lemonade Pet Insurance Announcer]

In my logical mind, I think if Mario did this, you'd have called one of your military sniper buddies. And it had been quick, easy, and nobody would have known the difference.

[Lester Holt]

Kim Jensen was talking to police before Tenen made his confession. But she certainly seemed to have her doubts about Tenen as the gunman. Flash forward to this year, Mike Tenen suddenly had his own doubts about what he'd confessed to. What's going on?

[DATELINE Producer Mike Nardi]

Yep. So bear in mind, Tennant pleaded guilty to a lesser charge of second degree murder. Really? Early on, back in 2023. And he agreed to testify against Gardner and Fernandez. But more recently, Tennant got a new attorney. And about a month ago, that attorney filed a motion saying Tennant wanted to withdraw his guilty plea, and the judge granted it. So now Tennant has officially pled not guilty to murder and will no longer cooperate with prosecutors.

[Lester Holt]

When Tennin withdrew his plea, that gave Mario Fernandez's defense an opening. You attended a hearing in Florida about that? Explain what was going on there?

[Josh Mankiewicz]

Yeah.

[DATELINE Producer Mike Nardi]

So Fernandez has been in jail since his arrest. He was denied bail early on, but in light of Tennant's change of plea, his attorneys again asked the judge that he be released on bond. The judge agreed to hear arguments on this. So I was in court last week when Mario's defense made its case. The gist of the argument is without Tennant's testimony, The prosecution has nowhere near enough evidence to keep Fernandez in jail while he awaits trial.

[Lester Holt]

An example the defense brought up is that in his signed confession, Tenon said Mario drove the truck at the scene of the murder. But without Tennin's testimony, nothing else ties Mario to the truck and the scene of the crime. Mr. Fernandez does not own a Ford F150. There is no connection between Mr. Fernandez and a Ford blue F150.

[DATELINE Producer Mike Nardi]

No DNA of Mr. Fernandez was found

[Josh Mankiewicz]

inside the blue Ford 150.

[DATELINE Producer Mike Nardi]

They also argued that they unearthed evidence proving the payments Fernandez made to Henry Tennant were legitimate, including a check to help him start his own business. There is no follow the money.

[Lester Holt]

We followed it, we found it. It dead end.

[DATELINE Producer Mike Nardi]

And that is the end of the story.

[Lester Holt]

So what's all this mean for Shanna Gardner?

[DATELINE Producer Mike Nardi]

[DATELINE Producer Mario Garcia]

Thanks for having me, Lester.

[Lester Holt]

For our first story, we're heading to Suffolk County, New York, in a story you know. Well, Mario, you've been covering it for several years now. That's the case of alleged Gilgo beach serial killer Rex Heerman, who is awaiting trial on charges that he murdered seven women and dumped their remains along Gilgo beach and other parts of Long island between 1993 and 2011. He has pleaded pleaded not guilty. What's new in the case?

[DATELINE Producer Mario Garcia]

Well, Esther, it's been going on and on and on and on, but there was a new court filing last week by prosecutors which gave us some more details at some of the evidence, the alleged evidence that they want to try to use in court against Heuerman. According to this latest filing, investigators discovered that Heuerman, using two different burner phones, contacted sex workers over some 500 times between January 2021 and February 2023.

[Lester Holt]

And the defense wants the judge to exclude this evidence. Why?

[DATELINE Producer Mario Garcia]

Well, the defense says the phone records are irrelevant and potentially prejudicial if a jury hears about them. They say just because Heuermann is contacting sex workers doesn't prove he's done anything wrong. But knowing he did, that could turn jurors against him. The prosecution completely disagrees. And in this filing, they say he had a pattern of behavior of interacting with these sex workers. And the burner phones are evidence of a consciousness of guilt, that he was hiding his tracks because he knew what he was doing was something wrong.

[Lester Holt]

And when do we think the judge will decide on this motion?

[DATELINE Producer Mario Garcia]

Well, we'll see, Lester. There's a hearing next week. The judge is expected to rule on this and some other pretrial issues. But several months ago, the judge said that this trial will start after Labor Day. But, you know, Christmas is after Labor Day, so maybe we'll find a trial date out, maybe we won't on March

[Lester Holt]

17, but sounds like we're getting closer. Well, next we have a big update in the trial of Dale Warner, the Michigan farmer accused of killing his wife Dee in 2012, 21, and hiding her body in a fertilizer tank. He pleaded not guilty to charges of murder and tampering with evidence. Mario, we've been covering this trial for weeks now. What's the latest?

[DATELINE Producer Mario Garcia]

Well, we finally have a verdict, Lester, but it was not without some fireworks in the days Leading up to that verdict. In the closing arguments last week, prosecutors painted a portrait for the jury of the couple's broken marriage and what Dale had to lose if Dee divorced him. Then Lester. Prosecutors methodically laid out a timeline of Dale's movements at the time of the murder and afterwards. They said that the time on surveillance cameras and from car apps proved that he used the farm equipment to move Dee's body to the farm spray barn and then spent two hours in that barn to cut open the fertilizer tank and then put her body in.

[Lester Holt]

How did the defense respond?

[DATELINE Producer Mario Garcia]

The defense emphasized that there was really no physical evidence connecting Dale to Dee's murder. Their key points? They said the prosecution couldn't prove when and where Dee died based on the testimony of the medical examiner, Dr. Patrick Choir.

[DATELINE Producer Karen Israel]

Dr. Cho doesn't know the time of Ms. Warner's death.

[Lester Holt]

Dr. Cho does not know the place of Ms. Warner's death.

[VRBO/Amica Insurance/Lemonade Pet Insurance Announcer]

Doctor Cho does not know if Ms. Warner was killed inside or outside.

[Lester Holt]

The jury got the case last Friday, but it sounds like there was some drama during the deliberations.

[DATELINE Producer Mario Garcia]

Indeed, one of the jurors didn't show up to court on the second day of deliberations because of a medical issue. Then the judge tried to call in three alternate jurors, but things got wackier from there. Lester? It turned out they had all discussed the case with other people already, and two of them had seen media reports about the case. Thankfully, on Tuesday, the original juror returned and deliberations got underway again.

[Lester Holt]

So after eight hours of deliberation spanning two days, they had a verdict. What was it?

[DATELINE Producer Mario Garcia]

The jury found Dale Warner guilty of second degree murder and tampering with evidence. According to our producer in the courtroom, Dale was motionless when the verdict came in until he heard second degree, and then his head dipped. Dee's family members hugged and cried afterwards.

[Lester Holt]

Dale will be sentenced in May, so we'll see what happens there. Finally, Mario, we're heading to federal court in Manhattan, where another big case came to an end this week. The sex trafficking trial of celebrity real estate brokers Oren and Tal Alexander and their other brother, Alon Alexander. Mario, tell us about these three brothers.

[DATELINE Producer Mario Garcia]

Well, Orrin and Tal Alexander sold ultra luxury properties to wealthy clients in New York and Miami, including Kim Kardashian and her ex husband, Kanye West. The brothers, along with Orin's twin brother, Alon, were charged by federal prosecutors with heinous crimes, including rape, sex trafficking, sex abuse, and sexual exploitation.

[Lester Holt]

The brothers pleaded not guilty. The trial has been going on for the past five weeks and there were no cameras allowed in the court. What did the prosecution present to the jury?

[DATELINE Producer Mario Garcia]

The prosecutors talked about the brothers having a so called playbook of sorts where they used their social status and wealth to lure in their victims and then incapacitated them with drugs or by force. Eleven women took the stand and testified against the brothers.

[Lester Holt]

And how did the defense respond to these allegations?

[DATELINE Producer Mario Garcia]

The brothers attorneys conceded that the brothers had built a lifestyle around pursuing women, but all of the sex was consensual.

[Lester Holt]

The jury didn't buy that argument. Mario they returned a verdict on Monday and found the brothers guilty on all counts. Our friends over at NBC News now had this statement from the prosecutor. This verdict cannot undo the effects of heinous abuse the Alexander's many victims endured. But it does send a message. New York want to bring an end to sex trafficking in all our communities. Mario the brothers face life in prison when they are sentenced in August and have indicated they do plan to appeal. We appreciate the update. Mario Good to talk to you.

[DATELINE Producer Mario Garcia]

Thanks for having me. Lester

[Lester Holt]

for our final story this week, we're joined by a very special guest. Josh Mankiewicz is here to talk about his brand new podcast series Trace of Suspicion. It's a compelling tale about the mysterious death of a young Marine, his widow's unusual behavior and a fight for justice that spans more than 10 years. And you'll never guess where it ends up. At least I didn't. Hi Josh, how you doing? I'm good. So, Josh, you've been covering this story for more than a decade. What keeps you coming back to it?

[Josh Mankiewicz]

This is a terrific story. You know, every time you think you understand in this story what has happened, you're gonna be wrong. But this is the story of a guy who died sort of inexplicably. Young guy, Marine, in great shape, in good health, suddenly drops dead and his wife ends up getting charged with his murder. And what happens then is just this astonishing chain of events. But the question that I want people to think about at the end is what constitutes justice? There are people who think that justice was served by this story and there are people who think that justice was not served. And you're gonna have to make up your own mind when you listen to this.

[Lester Holt]

So tell us about the couple at the center of this 23 year old Marine Sergeant Todd Sommer, his wife Cindy. What do we know about them when this story begins?

[Josh Mankiewicz]

Well, you know, he's a Marine. She'd been married before. She had three kids. They had this whirlwind Romance. And it was very hot and heavy very quickly. And then Todd was willing to not just marry her, but, like, take on her three kids. And then they had another kid together, a son, after they were married. And then he gets deployed as Marines do, and he's overseas, and he's away from her. And so suddenly, she's raising four kids on an armed salary, which is a very difficult thing to do. And their problems just sort of compound from there.

[Lester Holt]

You begin the story by painting a pretty vivid picture of the night Todd died. Cindy describes hearing him wake up and struggling to breathe. Let's take a listen to that. It's very dramatic.

[VRBO/Amica Insurance/Lemonade Pet Insurance Announcer]

He got up and he walked towards the bathroom and turned around and just looked at me and, like, just couldn't catch his breath. I went over to him. I'm like, what's the matter? He just looked at me and he said, I'm all right. I'm okay. I'm fine. And then he just fell down, and I just kind of freaked out.

[Lester Holt]

What was it about Cindy's behavior that made them suspicious that this might have been a murder case?

[Josh Mankiewicz]

First of all, this was a very healthy young Marine in very good physical condition who essentially just dropped dead after having been sick for, like, a week. And as they're taking him away, Cindy says to an MP who had come because of her 911 call, she says, wow, you know, Todd and I talked about the military's life insurance policy, but I never thought we would end up actually using it. And then at the hospital, after her husband's pronounced dead, a senior Marine officer, which is protocol, comes over and says, what can we do for you right now in this instant of this terrible bereavement? And she says to him, are we going to have to give back Todd's reenlistment money? So all of those things, when looked at through the lens of suspicion, that definitely sent an investigation in one direction, whereas otherwise it might have gone in another.

[Lester Holt]

Some of it was really centered around her spending patterns around all this time.

[Josh Mankiewicz]

First of all, she lived very large. Like, she was picking up a lot of checks, and she was going out with her friends a lot, and she got breast implants. And that is one of the things, along with some of her personal conduct, that pointed investigators towards looking at her for possibly having murdered her husband. I. I think that if she had gotten a nose job, things might have turned out differently.

[Lester Holt]

And then I guess the biggest breakthrough is this toxicology report that raised flags about Todd's cause of death.

[Josh Mankiewicz]

That toxicology report comes back positive for have him having a ton of arsenic in his system. And that's when the murder investigation really starts rolling.

[Lester Holt]

Cindy's obviously the enigma at. You interviewed her recently. It's the first interview, by the way, she's given about the case in years. What was interviewing her like?

[Josh Mankiewicz]

The last time I spoke with her was many years ago. And I didn't want to do this story without speaking to her again. And I went and visited her and did the interview in person, which is which produced a very interesting, wide ranging account of everything that had happened in her life. And she's had a fascinating journey.

[Lester Holt]

She really doesn't hold back. Here's what she told you in response to people, people's criticism about how she acted after Todd's death. Let's listen to that.

[VRBO/Amica Insurance/Lemonade Pet Insurance Announcer]

I'm not ashamed. Why does it matter? I didn't grieve how people thought I should. I didn't do the things that they thought I should. I did things that they didn't agree with. My moral compass may have been off.

[Lester Holt]

So two episodes are already available for listeners. What other surprises can listeners expect as this series unfolds?

[Josh Mankiewicz]

I ask people to sort of withhold judgment. Cause there's gonna be a lot of like, leaping to conclusions in this. What you think is going on. What you think is going on. It's a ride all the way to the end. All the way to present day.
