48 HOURS: THE PEOPLE V. KOURIE RICHINS

In the early morning hours of March 4, 2022, Kouri Richins says found her husband, Eric Richins, unresponsive in their bed. First responders tried to save him, but it was too late for the father of three. Weeks later, police said Richins' death was caused by an overdose of fentanyl. The grieving widow from Utah was arrested and charged with murder shortly after Paramount+.

In her first primetime interview, Kouri Richins' mother, Lisa Darden, tells Morales that hours before Eric Richins was found unresponsive the couple was celebrating a new house-flipping deal Kouri was working on. Kouri Richins told investigators night. But something didn't sit right when the medical examiner ruled Eric Richins overdosed on fentanyl, according to his family's spokesman, Greg Skordas.

“He wasn't an opioid user … This doesn't smell right,” says Skordas.

The Richins' children struggled with the loss of their father, so Kouri decided to write a children's book – Are You with Me? – about a boy who lost his father but is reminded his presence still exists all around. Kouri Richins promoted the book on local TV.

A month after her TV appearance, Kouri Richins was arrested and charged with her husband's murder. Prosecutors allege family suspects

“He told his family, ‘If I die, you need to take a look at her because I think kill me,'” Greg Skordas tells 48 HOURS.
