It's been almost four years since prominent L.A. therapist Amie Harwick was murdered on Feb. 15, 2020. For the first time, the man who tried to save her opens up about what happened. 

In the early morning hours of March 4, 2022, Kouri Richins says she 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 she wrote a children's book to help their kids cope with grief.
