The Kouri Richins Case: Children’s Book Author Tries to Murder Her Husband Three Times.
What would it feel like to live each day with the fear that the person sleeping beside you, the parent of your children, might secretly be plotting your death? It sounds like the premise of a chilling crime thriller. Yet in today’s case, that nightmare became reality.
A healthy husband with no serious medical history suddenly died in his own bedroom. At first glance, it looked like nothing more than a tragic medical emergency. But little by little, small details began to drift out of alignment.
What started as a mysterious death quickly evolved into one of the most cold-blooded and carefully calculated poisoning cases in recent American memory. This was not a plan put together in a matter of days. It was something that had been building for months, with earlier attempts that failed before one finally succeeded.
In this story, we follow the trail step by step through digital searches, private messages, witness statements, financial records, and forensic evidence. Taken together, those fragments formed the full picture of a crime that shocked the United States. And before long, the person at the center of that picture would no longer be seen as a grieving widow, but as the prime suspect in her husband’s death.
At 3:21 a.m. on May 4, 2022, emergency dispatchers in Kamas, Utah received a frantic 911 call. On the other end of the line was a panicked woman identifying herself as Kouri Richins. She said she had spent the night in one of her children’s rooms after the boy was frightened by a nightmare.
According to her, she woke sometime after 3:00 a.m. and returned to the master bedroom. When she touched her husband Eric Richins, she was horrified to find that his body felt cold, almost like concrete. Realizing he was not breathing, she called for help.
Emergency responders arrived quickly. By the time they got there, Eric was lying unresponsive on the floor and had no pulse. The rescue team attempted every available measure, including chest compressions, airway support, and naloxone in case of an opioid overdose, but nothing worked.
Eric Richins was pronounced dead at his home. News of his sudden death spread quickly to family members, and the Richins family was devastated. No one could believe that a healthy 39-year-old man had died so abruptly in the middle of the night.
While the medical examiner awaited formal orders for an autopsy, police conducted an initial search of the bedroom and bathroom. They did not find illegal drugs, suspicious medication, or anything that obviously pointed to foul play. There were only a few older prescription bottles belonging to Eric, including pain medication from 2016, antibiotics from 2019, and some THC gummies in a cabinet.
At first, the scene did not appear overtly criminal. There were no signs of forced entry, no evidence of a struggle, and no indication of theft. Eric had no visible injuries, and his personal belongings remained untouched.
For that reason, the death was initially treated as a sudden family tragedy, likely caused by a medical event. To outside observers, it looked like a heartbreaking but natural loss: a husband dead in the night, leaving behind a grieving wife and three sons. But to experienced investigators, the story had only just begun.
Several things immediately struck them as unusual. The first emergency responder to enter the bedroom observed that Eric’s body was lying straight and neatly positioned at the foot of the bed. In most cases, if someone is pulled from a bed to the floor for CPR, the body ends up beside the bed with limbs at odd angles and signs of hurried movement.
Instead, Eric appeared carefully placed. His arms and legs were straight, and his position suggested the body may have been moved or arranged before first responders arrived. That raised an unsettling possibility: had the scene been staged?
The second point was less concrete, but still noted. Kouri appeared distraught, crying heavily and covering her face with her hands. Yet investigators observed that she avoided direct eye contact and seemed oddly performative in her grief.
Of course, people react to shock in different ways, and unusual behavior alone means very little in a moment of crisis. Police did not treat this as proof of anything. But they documented it carefully in case it later proved relevant.
When questioned that morning, Kouri told officers that she and Eric had shared drinks and a late-night sandwich in the bedroom. She said she had made him a Moscow mule, a cocktail with vodka, ginger beer, and lime, to celebrate her recent success in purchasing a new property for business. Later, around 9:30 p.m., she said their youngest son had a nightmare, so she went to sleep in his room.
She claimed she stayed there through the night and only returned to the master bedroom after 3:00 a.m., when she found Eric unresponsive. Guided by emergency dispatchers, she said she tried to perform CPR, but was unable to revive him. Even then, however, Kouri seemed quick to suggest a cause of death.
She told relatives she believed Eric may have suffered a stroke or a brain aneurysm. She repeated that explanation in comments to the media. But investigators knew they could not rely on assumptions.
Only a full investigation would reveal what had really killed a healthy 39-year-old man in his own bed.
According to public records, Eric Richins was born in 1982 and raised in a close-knit Utah family. Friends described him as warm, hardworking, and easy to get along with. Before his death, he was the co-founder of C&E Stone Masonry, a business specializing in stonework and construction.
In 2013, Eric married Kouri Darden, despite some warnings from people who believed their personalities were very different. Eric was steady and reserved, while Kouri was more outgoing and forceful. They held their wedding in the backyard of a home in Utah, and by that point they already had their first son.
After the marriage, Kouri focused on building her own company, K. Richins Realty, which bought older homes, renovated them, and sold them for profit. In the beginning, her business did well, helped by a strong Utah real estate market. She earned impressive returns, cultivated the image of a successful entrepreneur, and contributed to a comfortable life for the family.
During the early years, the marriage appeared stable from the outside. The couple welcomed two more sons, bringing the total to three young boys. On social media, Kouri posted happy family photos from vacations and outings, presenting the image of an ideal home.
But behind closed doors, cracks had begun to form. Investigators later discovered that shortly after the wedding, Eric and Kouri had signed a prenuptial agreement. Under its terms, each person’s income and assets remained separate property.
There was, however, one important exception. If Eric died while they were still married, ownership of his company, C&E Stone Masonry, would transfer to Kouri. At the time, that provision may have seemed like a practical step to protect his wife and children if the worst happened.
It also showed the depth of Eric’s trust. He was willing to place the future of his business and much of his estate in the hands of the woman he loved. But years later, that trust began to erode.
Around 2018 and 2019, Kouri’s real estate business began to struggle. Ambition, poor timing, and risky investments pushed her into financial trouble. She had bought and renovated multiple homes at once, expecting fast returns, but market changes left those projects difficult to sell.
Debt began piling up. Eric initially tried to support her financially, but over time he noticed troubling irregularities in the family’s finances. By the fall of 2020, he discovered that Kouri had withdrawn money and used credit in his name without discussing it with him.
Even then, Eric did not report her. He did not go to police or publicly accuse his wife of financial misconduct. Instead, likely because of the children, he quietly began protecting what he could.
In October 2020, Eric met privately with an attorney and created the Eric Richins Living Trust. He transferred his home and his ownership interest in the company into that trust. Most importantly, he removed Kouri as the beneficiary of those assets.
He then named his sister, Katie Richins Benson, as trustee for the benefit of his sons. In other words, if something happened to him, Kouri would not control his property. It was a difficult decision, and it showed that Eric had begun to lose faith in her long before his death.
He also kept the changes secret. At the same time, he reportedly warned his sister and other family members that if anything ever happened to him, they should be suspicious of Kouri. It was a chilling statement, and in hindsight, a prophetic one.
The cruel irony was that while Eric was quietly removing Kouri from his estate, she was making her own moves to profit from his death. In January 2022, only two years after being removed from a previous $500,000 life insurance policy, Kouri secretly applied for a new policy on Eric worth $2 million.
She listed herself as the beneficiary and submitted the paperwork without his knowledge or consent. Eric discovered it and immediately canceled it because he had never signed off on the application. That act of forgery or attempted forgery only deepened his concern.
According to investigators, Eric had already begun preparing for divorce and intended to seek custody of the children after wrapping up several unfinished business matters. Under the terms of the prenuptial agreement, Kouri stood to walk away with very little if the marriage ended. She would not receive his company, and her financial position would be badly weakened.
But Eric never got the chance to follow through. Only weeks later, after his funeral, the family received shocking news from the Utah medical examiner. Eric had not died of a stroke, an aneurysm, or any natural medical event.
He had died from fentanyl poisoning. The amount of fentanyl found in his body was estimated at about five times the lethal dose for an average person. Medical examiner Dr. Pamela Schuerman concluded that Eric showed no evidence of stroke, heart disease, or any other natural cause of death.
The fentanyl alone had caused respiratory failure and killed him. That finding transformed the case overnight. Fentanyl is an extremely powerful synthetic opioid, far stronger than heroin, and is usually encountered in hospitals or on the black market.
Eric had no prescription for fentanyl, no history of illegal drug use, and no explanation for why such a substance would be in his system. His family strongly insisted that he did not use illicit drugs. That meant the fentanyl had to have come from somewhere else.
From that point forward, investigators no longer viewed the case as a possible accident. They believed they were dealing with an intentional poisoning. The focus shifted immediately to two questions: where had the fentanyl come from, and how had it entered Eric’s body?
Police executed a second, more thorough search of the Richins home with a special warrant. Even then, they found no fentanyl patch, no legal prescription, no loose powder, no pills, no syringe, and no paraphernalia indicating self-administration. There was also no evidence that an intruder had entered the house to poison him.
That left one person with the clearest combination of access, opportunity, and motive: Kouri Richins. In practical terms, suspicion now centered on Eric’s wife.
Detectives from the Summit County Sheriff’s Office and narcotics investigators began tracing Kouri’s activities in the weeks and months before Eric’s death. They seized and analyzed her phone and computer. Very quickly, those devices opened an enormous reservoir of disturbing information.
Financial records showed that by May 2022, Kouri was drowning in debt. She owed at least $1.84 million to private lenders. Investigators also found evidence of escalating conflict between husband and wife over money, especially over a high-priced property deal.
Kouri wanted to purchase a nearly $2 million home in Midway as an investment. Eric strongly opposed the purchase because their finances could not support it. Investigators later learned that Eric had planned to tell her on May 5, the day after his death, that he would not sign the paperwork.
That timing would prove devastating. Because less than twenty-four hours after Eric died, Kouri signed the documents to buy the house herself, portraying it as a decision connected to the dream they had supposedly shared. Investigators saw it very differently.
To them, it looked like immediate movement toward a financial objective that Eric had blocked while alive. And the property was only one part of what she stood to gain. Insurance money and inheritance benefits were the larger prize.
Investigators found that Eric’s life insurance coverage totaled more than $2 million, and Kouri believed she was the beneficiary. She did not realize that Eric had already changed some of those arrangements and moved control away from her. In Kouri’s mind, however, Eric’s death may have looked like the key to escaping financial collapse and gaining access to millions.
Digital evidence made the picture even darker. On Kouri’s devices, investigators found internet searches that included phrases like what drugs can make someone appear to have a stroke, how long do people in Utah go to prison, and can police force you to take a lie detector test. Those searches suggested not panic after a tragedy, but planning before one.
Even more disturbing, detectives concluded that Eric’s death may not have been the first attempt on his life. Family members told police that years earlier, during a trip to Greece, Eric became mysteriously ill after drinking something Kouri gave him. He ended up hospitalized and later told his sister that if anything happened to him, she should suspect his wife.
Then there was another incident, only weeks before his death, around Valentine’s Day in 2022. Eric ate a sandwich Kouri had brought him and almost immediately developed a severe allergic-style reaction. He broke out in hives, his throat began to swell, and he struggled to breathe, requiring urgent medication.
Eric reportedly told friends that he had never had food allergies and felt that something was wrong. Looking back, investigators believed those earlier episodes may have been failed attempts. By the third time, they believed, the plan finally worked.
Yet while police were still trying to determine what happened, Kouri was publicly crafting an entirely different image. She published a children’s book titled *Are You With Me?*, marketed as a tool to help children cope with the loss of a loved one. During interviews and appearances, she presented herself as a bereaved widow trying to guide her sons through grief.
Investigators came to believe it was all part of a performance. More than a year after Eric’s death, in 2023, Kouri was interviewed again. This time, police had forensic results, financial evidence, digital records, and witness statements.
Under questioning, she continued to deny any involvement. She repeated her account of discovering Eric cold in bed and tried again to suggest that he may have taken drugs himself or died from an unexplained medical event. But by then, the objective evidence was working against her.
According to the prosecution’s theory, on the night Eric died, Kouri prepared him a cocktail as a celebratory drink tied to the new property purchase. Hidden inside that drink, investigators believed, was a massive dose of fentanyl. Sometime between 9:00 and 10:00 p.m., she then used their child’s nightmare as an excuse to leave the bedroom.
Eric remained there alone, unaware that he had just consumed a fatal amount of poison. As the fentanyl took effect, his breathing slowed and then stopped while he slept. Medical evidence suggested he may have died within roughly an hour, long before the 911 call after 3:00 a.m.
That gap raised another troubling theory: that Kouri waited deliberately before calling for help, ensuring there would be no chance of saving him. After Eric’s death, she moved quickly into the role of grieving widow. She organized funeral arrangements, accepted donations, and received insurance money, including about $1.3 million that automatically went to the legal spouse.
She also completed the purchase of the $2 million property Eric had opposed. To reassure skeptics, she repeatedly claimed he had died from a brain aneurysm, even when relatives expressed doubt. But the final key question remained: where had the fentanyl come from?
That answer emerged through phone data. Investigators discovered that in late 2021, Kouri had contacted a woman named Carmen, who had previously cleaned for the Richins family. In their messages, Kouri asked whether Carmen still knew anyone who could get pain pills.
When Carmen said yes, Kouri asked her to obtain powerful medication, claiming it was for someone with back pain. Investigators believed Carmen had unknowingly acted as an intermediary. She then contacted a man known as “Red” in Ogden, Utah, who was allegedly involved in drug dealing.
At first, Carmen obtained a weaker opioid, hydrocodone, for Kouri. Kouri paid well, which encouraged further cooperation. Then, in early 2022, Kouri asked for something much stronger, saying her acquaintance needed very strong pain medication.
Prosecutors argued this marked an escalation after earlier attempts had failed. This time, the pills were blue tablets made to resemble Percocet but actually contained fentanyl. On May 2, 2022, Carmen and a friend drove to meet the dealer and collect the drugs for Kouri.
The transaction was delayed but eventually completed. They received a package containing fifteen dark blue pills. Kouri allegedly left $900 in cash under a doormat for pickup and later wrote an additional $1,300 check disguised as a payment for house-cleaning work connected to a Midway property.
On May 2, Carmen delivered the pills to Kouri at one of the homes she was renovating. Those small blue pills, according to prosecutors, became the murder weapon only days later. By then, investigators believed they had enough to act.
On March 8, 2023, Kouri Richins was arrested. She was charged with aggravated murder and multiple drug-related offenses. As the broader investigation continued, authorities also uncovered a wide range of alleged financial crimes, including forged signatures, insurance fraud, and theft-related conduct.
In addition to the homicide count, she ultimately faced nearly thirty criminal charges. And investigators uncovered yet another layer to the story: Eric had allegedly been betrayed romantically as well.
In 2020, Kouri reconnected with an old boyfriend named Robert George Grossman. After moving to Utah, he began working for her company and stayed in one of the homes she was renovating. Their old connection quickly became an affair.
Messages between them showed Kouri telling him she was unhappy in her marriage and wanted to leave Eric. In some texts, she suggested that life would be perfect if her husband simply disappeared. Those exchanges painted Eric not only as an obstacle to her finances, but also to her romantic freedom.
At one point in May 2022, Kouri reportedly asked Grossman whether he would marry her if she divorced Eric and proposed the next day. Grossman said he loved her and would say yes. Investigators argued that these messages showed motive clearly: she wanted out of the marriage, but not at the cost divorce would bring.
Grossman later told investigators something else deeply unsettling. Only two weeks after Eric’s funeral, Kouri asked him whether he had ever killed anyone and what it felt like. Grossman, a military veteran, said he was confused and disturbed by the question, but at the time still accepted her explanation.
Only after her arrest did he realize how dangerous she might have been. Kouri was taken into custody at her home. To people who knew her, the allegation that she had murdered her husband was almost impossible to process.
Just weeks earlier, she had appeared on television promoting her children’s grief book. Now she was in handcuffs on her way to the Summit County jail. Her defense attorneys insisted she was innocent and claimed the media had distorted the case.
In June 2023, Kouri Richins appeared in court for the first time, denied all charges, and requested a trial. The case moved into public proceedings and drew intense national attention. Every hearing drew more scrutiny and more headlines.
The trial of Kouri Richins began on April 12, 2026, in Summit County, Utah, near Park City. She appeared in court wearing formal attire and maintained a composed expression. Over the course of the trial, witness testimony and forensic evidence gradually stripped away the façade.
Key witnesses, including Carmen and Robert Grossman, detailed the chain of events linking Kouri to the acquisition of fentanyl and to the motive behind Eric’s death. Family members described Eric’s fear of his wife. Forensic experts testified that the death was not a random overdose or medical anomaly, but a deliberate poisoning.
By the time the jury retired to deliberate, the outcome appeared all but inevitable. After only three hours, they returned with a guilty verdict. Kouri lowered her head and remained silent.
Because of the aggravating factors, including financial motive and poisoning, she now faces a sentence of life without parole. The role of grieving widow can no longer be performed on television, in interviews, or in book promotion. It can only continue behind prison walls.
The case may be legally resolved, but its aftershocks remain. Across Utah and throughout the United States, people were stunned by the story of a widow who wrote a children’s book about grief while allegedly having caused the very loss she claimed to mourn. Reports even surfaced suggesting that the book itself may have been ghostwritten, adding yet another layer to the deception.
After Kouri’s arrest, bookstores quickly pulled *Are You With Me?* from shelves. Many parents who had purchased the book felt betrayed when they learned who the author really was. What had once been marketed as a comforting story for children became, in the public mind, a chilling artifact of manipulation.
As for Eric’s family, they have continued trying to rebuild. His three young sons are being cared for by his side of the family. Eric’s sister, Katie, has worked to carry out his wishes by keeping Kouri away from both the children and the assets he tried so hard to protect.
Through the trust Eric created before his death, Katie also filed a civil lawsuit seeking $10 million in damages, including the value of business interests and property that Kouri allegedly attempted to seize. Whether that money can ever be recovered is uncertain. But the legal action serves another purpose as well.
It creates a final barrier between Kouri and anything she might still try to claim from Eric’s estate. More importantly, it protects the future of the boys he left behind. And in a case defined by betrayal, that may be the closest thing to justice still possible.
