Summary
Ryan Holden, Senior Forensics Scientist, takes center stage in the Kouri Richins trial.
Kouri Richins stands accused of poisoning her husband Eric Richins with a lethal dose of fentanyl in March 2022—allegedly to collect on a $1.9 million life insurance policy she secretly increased just weeks before his death. What prosecutors describe as a calculated murder-for-profit scheme, the defense calls a tragic accident involving a man who, they claim, had a hidden drug problem.
This is gavel-to-gavel coverage of one of the most closely watched trials in Utah history. A children's book author. A grieving widow who wrote about "heaven" for kids while allegedly researching untraceable poisons. A husband who may have been killed in his own bed.
Hidden Killers brings you complete trial coverage with expert analysis—no sensationalism, just the facts as they unfold.
