A month from now, a jury in Summit County, Utah, will be asked to decide whether Kouri Richins murdered her husband Eric by slipping fentanyl into his drink — or whether this is all a catastrophic misunderstanding involving a grieving mother who just happened to write a children’s book about death after her husband died under circumstances that made investigators very, very uncomfortable.
Kouri Richins has pleaded not guilty. She maintains her innocence. She has said publicly that she did not murder her husband. And in about thirty-two days, she’ll get her chance to say that to a jury.
But this week, before any of that happens, Judge Richard Mrazik handed down a cascade of pre-trial rulings that define exactly what that jury will hear. And maybe more importantly — what they won’t. Because trials aren’t about truth. They’re about admissible truth. And a significant amount just got carved out of this case.
Let’s back up for anyone just tuning in. Eric Richins, 39 years old, was found dead in the couple’s bedroom in Kamas, Utah, on March 4, 2022. According to the autopsy, he had five times the lethal dose of fentanyl in his system. The medical examiner determined it was illicit fentanyl — street drugs, not medical grade. His wife Kouri told police they’d been celebrating a business deal that night. She allegedly said they’d had Moscow Mules together before bed. She said she’d fallen asleep in one of their sons’ rooms and found Eric cold and unresponsive when she came back to the bedroom around 3 a.m.
Prosecutors allege this wasn’t a one-time event. According to charging documents, seventeen days before Eric died, on Valentine’s Day 2022, Kouri allegedly left his favorite sandwich from a local diner in the front seat of his truck with a love note. According to court filings, Eric took one bite of that sandwich and broke out in hives. He allegedly couldn’t breathe. He used his son’s EpiPen, chugged Benadryl, and passed out. When he woke up, according to prosecutors, he called a friend and said the words that would later echo through this entire case: “You almost lost me.” Prosecutors allege Eric told that friend he believed his wife had tried to poison him.
The state’s theory is straightforward: Kouri allegedly learned from the Valentine’s Day attempt that putting fentanyl in a sandwich didn’t work — Eric could take a bite, feel sick, and stop eating. So seventeen days later, according to prosecutors, she allegedly put a massive dose into a drink — what prosecutor Brad Bloodworth described as a “lemon shot” — something Eric would throw back all at once. According to Bloodworth’s arguments in court, Kouri allegedly wrote about this in a journal. The state claims she learned that “it takes a truckload of fentanyl to kill him” and that “it has to be administered at once.”
That’s the prosecution’s narrative. The defense has attacked it from multiple angles. They’ve pointed out that no fentanyl pills were ever found in the Richins home. They’ve noted that the man who allegedly sold fentanyl to Kouri’s housekeeper — who then allegedly passed it to Kouri — has since recanted his statement. Robert Crozier now claims he sold OxyContin, not fentanyl, and says he was detoxing and “out of it” during his original interview with detectives. The defense has argued that if the state can’t prove Kouri ever had fentanyl in her hands, they have no case.
That’s the backdrop. Now let’s talk about what happened this week.
Judge Mrazik issued a series of rulings that will shape what this jury sees and hears. Some favor the prosecution. Some favor the defense. But the cumulative effect is a trial that will be narrower than prosecutors wanted — and potentially more focused than the defense hoped.
The biggest blow to prosecutors: the financial crimes are out. The state desperately wanted to try the fraud and forgery charges alongside the murder. Insurance fraud. Mortgage fraud. Forgery. The whole alleged tapestry of a woman who, according to the state, had been running financial schemes for years — forging Eric’s signature on documents, manipulating life insurance policies, racking up debt through her house-flipping business that allegedly left her company owing lenders at least $1.8 million while Eric’s estate was worth approximately $5 million.
Judge Mrazik said no. He ruled those alleged financial crimes are not “an integral or natural part” of the murder itself. The charges will be tried separately. The jury deciding whether Kouri killed her husband won’t hear about the fraud allegations as criminal charges.
Now, prosecutors can still present evidence of her financial circumstances — her debt, her situation, the pressure she was allegedly under. But they can’t call it fraud. They can’t present it as a pattern of criminal behavior. The jury won’t see those charges on the table when they’re deliberating murder.
Why does this matter? Because the prosecution wanted to tell a story of escalation. A woman who allegedly manipulated finances for years. Who allegedly forged documents. Who allegedly changed insurance policies behind her husband’s back. And who — when the walls started closing in — allegedly escalated to murder. That narrative just got surgically reduced.
Here’s another significant ruling. Kouri apparently told Eric’s father at some point that Eric had punched her. Gave her a black eye. Split her lip. According to court documents, she claimed she had video evidence of this. She never produced it. No video was ever found on her phone.
The judge ruled that abuse allegation is out. Prosecutors successfully argued it was irrelevant and prejudicial. In plain terms: the defense doesn’t get to suggest Eric was violent toward Kouri without evidence to back it up — especially when she allegedly said she had proof and the proof doesn’t exist. If the defense was planning to float any version of “she was defending herself” or “she was a battered woman,” that avenue just closed.
Related to that: the domestic violence expert is barred. Prosecutors wanted to call Dr. Sheri Vanino, a psychologist who specializes in domestic violence and coercive relationships. The idea was to explain why a victim might stay with someone dangerous, why someone might not leave even when they know they’re in peril. Defense attorney Kathryn Nester told the court there’s no evidence of domestic violence anywhere in twelve terabytes of discovery material. The judge agreed. Vanino is out — for now.
But there’s a conditional element here. If prosecutors can establish during trial that Eric knew Kouri had already tried to kill him — if they can prove he was aware of the Valentine’s Day incident and understood it as a poisoning attempt — then Vanino could potentially be called to explain why someone might stay in that situation. The door isn’t permanently locked. But right now, it’s closed.
The FBI profiler presented a more complicated question. Molly Amman, a former behavioral threat analyst, was challenged by the defense as relying on “junk science.” Her specialty is something called “pathway to violence” analysis — essentially, behavioral patterns that can indicate escalation toward targeted violence.
Judge Mrazik didn’t throw her out entirely, but he put her on a very short leash. Amman can only testify as a rebuttal witness. She can only speak if the defense argues it’s not credible that someone would engage in a weeks-long campaign to murder their spouse. And even then, she cannot suggest Kouri fits a “behavioral profile” of a killer. She cannot be used as direct evidence of guilt. Prosecutors can’t bring her in to say “this is what murderers look like, and Kouri looks like one.” That door is closed.
The handwriting expert, however, is fully in. Matt Throckmorton is a forensic document analyst. The state alleges Kouri forged Eric’s signature on insurance documents — including a policy that allegedly went into effect just ten days before the Valentine’s Day incident, with a death benefit of $100,000.
The defense called handwriting analysis subjective and unreliable — no better than everyone in the courtroom just guessing whether signatures match. The judge disagreed. Throckmorton will testify. He’ll offer his expert opinion that there’s a strong probability Eric did not sign at least one of those insurance documents — and that Kouri allegedly did. This is significant. Insurance manipulation is central to the prosecution’s motive theory. Throckmorton puts professional credibility behind it.
Now we get to the writings. The orange notebook has been fought over for months. Investigators found it in the Richins home — five pages, handwritten, allegedly by Kouri herself. According to prosecutors, it contains her firsthand account of the night Eric died. Her timeline. Her movements. What he ate and drank. The state argues that when you compare it to other evidence in the case, it makes it more probable she poisoned him.
The defense has contested this notebook from the start. They’ve argued prosecutors can’t prove when she wrote it or under what circumstances. They’ve also raised the fact that it was initially seized without a proper warrant — deputies grabbed it during a search on May 8, 2023, the same day Kouri was arrested, before they had authorization to take “documents or writings.” Prosecutors had to argue “inevitable discovery” — that they would have found it legally anyway.
Judge Mrazik’s ruling: the notebook can potentially come in, but only if prosecutors meet specific evidentiary requirements at trial. It’s not automatically admitted. They have to earn it. But the door is open.
Then there’s the letter. The “Walk the Dog” letter, they’re calling it. Found in Kouri’s jail cell. Written to her mother. Prosecutors allege it shows Kouri coaching her family on what to say — or not say — on the stand. The judge ruled portions of it are admissible. Other portions are out because they contain what appears to be her former attorney’s legal strategies, which is protected work product. What exactly the jury will see hasn’t been made public yet.
One more thing still hanging: Eric’s alleged drug use in high school. The defense wants the jury to know he had a history with substances. If that comes in, it could support an argument that Eric’s death was accidental — that maybe he obtained fentanyl himself, that maybe this wasn’t murder at all. If it stays out, that theory loses significant support. Judge Mrazik said he’ll decide during trial, outside the jury’s presence. So we won’t know until it happens.
Several other rulings remain pending. Some portions of Kouri’s interview with detectives were admitted; others are still undecided. Certain jail calls and text messages the prosecution wants to use haven’t been ruled on yet. There’s another hearing scheduled for February 2 to address what’s left.
Here’s the bigger picture. Prosecutors wanted a sprawling case. Financial crimes woven through everything. Behavioral profiling. Domestic violence dynamics. Years of alleged manipulation building toward murder. A woman who allegedly forged documents, allegedly manipulated insurance policies, allegedly had an affair, allegedly texted her lover the day after Valentine’s Day that “if he could just go away, life would be so perfect” — and then, seventeen days later, allegedly made him go away.
What they’re getting instead is a tighter trial. The murder charge. The attempted murder charge. The Moscow Mule. The Valentine’s Day sandwich. The insurance maneuvering. The handwriting expert. Potentially the orange notebook. But without the full fraud mosaic surrounding it.
The defense wanted out of Summit County entirely. They argued media coverage has been so pervasive — local, national, international — that Kouri can’t get a fair trial where it happened. They lost. The Utah Supreme Court already denied expanding the jury pool to include Salt Lake County. She’s being tried in Summit County, by people who live in Summit County.
Both sides agreed to close Thursday’s evidentiary hearing to the public. Jury questionnaires have already been sent out and returned. They couldn’t risk potential jurors hearing arguments about evidence that might not even be admissible.
Jury selection begins February 10th. The trial runs five weeks, Monday through Thursday, through March 26th.
In that courtroom, twelve people will hear about a Moscow Mule and a Valentine’s Day sandwich. They’ll hear about life insurance policies and allegedly forged signatures. They’ll hear about a woman who allegedly stood on the edge of financial collapse while her husband’s estate was worth millions. They’ll hear about a children’s book called “Are You With Me?” — published one year after Eric died — featuring a father with angel wings watching over his young son from heaven.
What they won’t hear is everything prosecutors wanted them to hear. They won’t see the full fraud charges. They won’t hear the domestic violence expert. They won’t get an FBI profiler telling them what killers look like.
The jury won’t know everything. They never do. But they’ll know enough to decide which version of Kouri Richins they believe — the grieving widow who wrote a book to help her sons, or the woman who allegedly poisoned her husband twice, succeeded on the second try, and then monetized his death with a picture book.
Kouri Richins says she didn’t do it. She says the world hasn’t heard who she really is or what she really didn’t do.
In just weeks, twelve people start deciding whether they believe her.
