GUILTY: Poisoned Husband Then Wrote Children’s Book

A Utah jury has convicted Kouri Richins of murdering her husband with a fentanyl-laced Moscow Mule cocktail, ending a trial that exposed a calculated plot involving poisoning attempts, insurance fraud, and a disturbing children’s book about grief published after the killing.

Story Snapshot

  • Kouri Richins found guilty of aggravated murder for fatally poisoning husband Eric with fentanyl five times the lethal dose on March 4, 2022
  • Prosecution evidence revealed $4 million debt, alleged affair, and prior Valentine’s Day poisoning attempt on husband’s sandwich
  • Defendant published children’s grief book after husband’s death while concealing alleged murder plot involving $1,300 fentanyl purchase
  • Defense rested without calling witnesses, failed to challenge medical examiner findings and witness testimony about drug acquisition

Calculated Poisoning and Evidence Trail

Kouri Richins murdered her husband Eric on March 4, 2022, by spiking his Moscow Mule with illicit fentanyl at their Park City, Utah home. Medical examiners determined Eric died from fentanyl intoxication at levels approximately five times the lethal dosage. Prosecutors established Richins paid $1,300 to acquire the deadly drug and deliberately administered it while the couple consumed drinks together. The prosecution presented witness testimony confirming Richins’ purchase and digital evidence showing Google searches about fentanyl intoxication, demonstrating premeditation and knowledge of the substance’s lethality.

Financial Motive and Marriage Breakdown

The prosecution revealed converging motives behind the murder: Richins carried approximately $4 million in debt, engaged in an alleged affair, and stood to benefit financially from Eric’s death through life insurance payouts. Eric Richins had consulted a family law attorney about the deteriorating marriage and changed his life insurance beneficiary in March 2020, two years before his death. These actions demonstrated Eric’s awareness of marital problems and efforts to protect himself financially. Prosecutors also presented evidence of a prior poisoning attempt on Valentine’s Day 2022, when Richins allegedly spiked her husband’s sandwich with fentanyl approximately three weeks before his death.

Children’s Book and Public Deception

Following her husband’s death, Richins self-published a children’s book titled “Are You with Me?” about grief, presenting herself publicly as a grieving widow and mother to three young boys. This brazen act of deception occurred while she allegedly concealed her role in Eric’s murder. From Summit County jail, Richins released an audio recording proclaiming innocence and emphasizing her identity as Eric’s wife and mother. Eric Richins’ family responded with a statement characterizing her claims as “the rantings of a sociopath, a woman who has no compassion, no feelings, no sense of remorse or guilt for what she’s done and is only thinking of herself.”

Defense Strategy Fails

The defense team rested without calling any witnesses, and Richins waived her right to testify during the March 2026 trial. Defense attorneys challenged how Eric ingested the drug and criticized investigators for allegedly failing to thoroughly test evidence, but offered no alternative explanation for the victim’s death. This strategic decision implicitly acknowledged the prosecution’s substantial evidence while attempting to raise reasonable doubt about proof beyond certainty. The jury ultimately rejected this approach, finding the medical examiner’s findings, witness testimony about fentanyl acquisition, and digital evidence compelling enough to establish guilt on aggravated murder charges.

The conviction holds Richins accountable for exploiting the fentanyl crisis to commit premeditated murder motivated by financial gain and personal betrayal. Her three sons now face life without either parent, as their father lies dead and their mother confronts potential life imprisonment. The case demonstrates how deadly synthetic opioids have become weapons accessible to those with criminal intent, reinforcing concerns about border security failures that allow illicit fentanyl to flood American communities and destroy families.
