In a courtroom drama unfolding in Summit County, Utah, prosecutors have painted a chilling picture of Eric Richins’ final hours: a seemingly healthy 39-year-old father retiring to bed after sipping a Moscow Mule crafted by his wife, Kouri Richins, only to be discovered lifeless by morning. The March 4, 2022, incident at their upscale Kamas home has evolved into a high-profile murder trial, with toxicology reports revealing a staggering five times the lethal dose of fentanyl in his system. Detectives are zeroing in on the kitchen where the cocktail was prepared, probing for evidence of premeditated poisoning amid allegations of financial desperation, an extramarital affair, and a web of deceit.

Kouri Richins trial: What we’ve learned so far in the Utah murder trial | CNN

Eric Richins, a successful masonry business owner and devoted dad to three young sons, had no history of drug abuse. On the evening of March 3, 2022, the couple celebrated Kouri’s recent real estate deal closure. According to her initial statements to police, she mixed a Moscow Mule—vodka, ginger beer, and lime—in the kitchen and served it to Eric in their bedroom. He drank it, they went to sleep (with Kouri reportedly in a child’s room due to a night terror), and she found him unresponsive around 3 a.m., cold and not breathing. First responders confirmed his death at the scene, initially attributing it to natural causes.

But an autopsy shattered that illusion. Medical examiner testimony during the trial, which began February 23, 2026, detailed illicit fentanyl levels at 13.6 ng/mL in Eric’s blood—far exceeding the 3 ng/mL lethal threshold. His gastric contents showed undigested fentanyl, indicating oral ingestion shortly before death. Quetiapine, a sedative sleep aid, was also detected at high concentrations (16,000 ng/mL in stomach fluid), raising questions about whether it was added to induce drowsiness, masking the fentanyl’s bitter taste and ensuring he consumed the fatal mix.

Prosecutors allege this was no accident. Kouri Richins, now 35, faces aggravated murder, attempted homicide, forgery, and fraud charges. They claim she sourced fentanyl through her housekeeper, Carmen Lauber, who testified under immunity that Kouri requested “stronger” pills, ostensibly for euthanasia but allegedly crushed into the cocktail. Lauber provided inconsistent statements but detailed selling Kouri fentanyl-laced pills multiple times, including a batch just before Eric’s death.

The kitchen has become a focal point. Investigators scrutinized the area for traces of fentanyl residue, though none was publicly confirmed. The Moscow Mule’s strong ginger flavor could have concealed the drug’s bitterness, prosecutors argue. Eric rarely drank cocktails, preferring beer, which adds to the suspicion. Defense attorney Skye Lazaro counters that Eric battled Lyme disease pain and may have self-medicated, but no evidence supports fentanyl use.

This wasn’t the first attempt, per the state. On Valentine’s Day 2022, Kouri allegedly laced a sandwich with fentanyl during a romantic outing, causing Eric severe hives, swelling, and blackout. He used his son’s EpiPen and Benadryl to survive, later confiding to friends and family: “I think my wife tried to poison me.” He warned his sisters to suspect Kouri if anything happened to him. Hours before his death, Eric messaged family about his fears, echoing earlier suspicions.

Motives abound. Kouri was drowning in $1.8 million debt from her real estate ventures. She secretly took out life insurance policies on Eric worth millions, forging signatures and altering estate documents. Text messages revealed her affair with handyman Robert Josh Grossman, who testified tearfully about her asking if he’d “ever killed anyone” days after Eric’s death. In messages, she fantasized about divorcing Eric, collecting insurance, and starting fresh.

Post-death behavior raised red flags. Kouri hosted a party at their home the day after, celebrating the deal while Eric’s body was barely cold. She deleted over 800 texts around the time and searched how to erase data permanently. Weeks later, she self-published “Are You With Me?”, a children’s book on grief, promoting it on TV as a tool for her sons. Prosecutors call it a cynical cover; defense says it shows genuine mourning.

Trial highlights include neighbor Becky Lloyd’s testimony: Kouri once said, “It would be better if Eric were dead” during a fight. Eric’s sisters recounted his poisoning fears from a Greece vacation illness. Forensic phone data showed Kouri’s searches on deleting messages, insurance payouts, and fentanyl poisoning.

Kouri maintains innocence: “I did not kill my husband.” Her team portrays a strained marriage but no murder, suggesting Eric’s partners or accidental overdose. She faces life without parole if convicted.
