📋 Summary

The Book of Lies: A Deep Dive into the Corey Richens Case

In this episode of Talking Dateline, host Blaine Alexander and correspondent Andrea Canning dissect the chilling murder case of Eric Richens, a 39-year-old father who died suddenly, leading to the eventual arrest and conviction of his wife, Corey Richens. The case gained notoriety not only for the method of murder—poisoning via a lethal dose of fentanyl—but for the bizarre sequence of events that followed.

The Diabolical Grief Narrative

Corey Richens’ actions following her husband's death were described as "diabolical behavior" by the hosts. Shortly after Eric’s passing, Corey wrote a children’s book about grief, which she promoted on a local lifestyle television program, Good Things Utah. Andrea Canning highlights the absurdity of this, noting that while the show’s co-host, Dina, intended to provide a sensitive platform for a grieving mother, she inadvertently became part of a "murder mystery" once an anonymous tip exposed the reality behind the facade. The book itself, illustrated with images of Eric as a "guardian angel," stands as a haunting testament to the disconnect between Corey’s public persona and the prosecution’s evidence.

Unwitting Intersections and Community Impact

The investigation revealed how deeply this crime touched the local community. From the owner of a local diner, Gabe—who found his establishment at the center of a murder investigation—to the unsuspecting homeowner who purchased a house from one of Corey’s LLCs, many individuals were "unwittingly in some way tied to this." Even the couple’s mutual friend, Linda from Home Depot, who had been a staunch supporter of their romance, expressed profound heartbreak upon realizing the truth. This web of connections highlights the shock waves sent through the area when a seemingly normal lifestyle was exposed as a cover for a "murder plot."

The Role of the Private Investigator

A pivotal figure in the case was private investigator Todd Gabler, hired by the Richens family. Unlike an amateur who might "fall down the rabbit hole," Gabler maintained a professional detachment, aiming to uncover the objective truth regardless of what the family wanted to hear. His investigation into Corey’s financial dealings and her secret lover, Josh Grossman, proved instrumental. In a particularly revealing moment, Grossman admitted to keeping a "wallet will" in case anything happened to him, fearing Corey’s potential involvement in Eric's death—a testament to the pervasive suspicion surrounding her.

Marital Strain and the "Whole Truth"

The relationship between Corey and Eric was reportedly fraught with tension long before his death. The hosts discuss red flags, such as Eric quietly changing his will and the couple signing a prenup "five minutes before she’s walking down the aisle" while she was in her wedding dress. The trial also featured a bizarre moment when Josh Grossman, the secret lover, questioned the court’s requirement to tell the "whole truth," which the hosts noted as an "immediate shot to his credibility."

Conclusion and Sentencing

The case concluded with a conviction, as the jury found Corey guilty on all counts. While the verdict provided a sense of relief to Eric’s family, the hosts emphasized that there is "never a sense of closure" when a life is lost. As the community moves forward, the case remains a stark reminder of the dark secrets that can hide behind a curated public image, with sentencing scheduled for a poignant date: Eric’s birthday.
