This is the Day 4 Trial report of the murder trial (expected to last until 23rd March 2026) of Kouri Richins, accused of poisoning her husband Eric Richins with Fentanyl, designed to catch you up with the nucleus of the case efficiently!
Case Report
Factual background:
In March 2022, Eric Richins was found unresponsive in the bedroom of the home he shared with his wife, Kouri Richins, in Utah. A 911 call was placed in the early morning hours reporting that he was not breathing.
Emergency responders arrived and Eric was pronounced deceased.
A subsequent autopsy and toxicology testing determined that Eric died from acute fentanyl intoxication. The level of fentanyl detected was reported to be significantly elevated.
Following investigation, prosecutors charged Kouri Richins with aggravated murder and related financial crimes. The State alleges that she intentionally administered fentanyl to her husband. The prosecution has also referenced an alleged prior poisoning attempt weeks before his death.
Investigators examined:
- Financial records, including real estate debt and loans.
- Life insurance policies associated with Eric Richins.
- Digital communications and phone data.
- Statements made during the 911 call and at the scene.
The State has argued that financial pressure and marital instability provide motive.
The defense disputes that the State can prove how fentanyl was ingested, challenges aspects of the financial narrative, and maintains that the prosecution cannot establish intentional poisoning beyond reasonable doubt.
Kouri Richins has pleaded not guilty.
The case proceeds as a circumstantial homicide prosecution centered on toxicology evidence, financial documentation, and competing interpretations of marital and post-death conduct.

UT v. Kouri Richins – Day 4 Trial Summary
Day 4 shifted the prosecution’s case from laboratory science into digital authentication and alleged drug procurement. The morning completed cross-examination of Chelsea Gibson, focusing on repeated searches and investigative scope. The toxicology findings were reinforced through Brianna Peterson, confirming illicit fentanyl at 29 ng/mL while preserving uncertainty about ingestion timing and method. Digital evidence authentication followed through device seizure and extraction testimony. The most consequential testimony came from Carmen Lauber, who alleged she purchased drugs for the defendant on four occasions and described text communications, payment, and delivery instructions. Cross-examination immediately placed her credibility, prior inconsistent statements, and cooperation incentives into issue. Court adjourned with cross-examination ongoing.
