5 Traits of Partners Who Poison — A Psychologist Explains

from Criminally Obsessed · host Criminally Obsessed

All eyes are on the trial of Kouri Richins, the Utah mom accused of murdering her husband by poisoning his cocktail with a lethal dose of fentanyl in 2022. Following her husband’s death, Kouri wrote a children’s book about grief and healing for her kids – which prosecutors are trying to prove was just part of her painting a narrative of being a good mother, not a murderer. We learned from forensic expert and host of the Body Bags podcast, Joseph Scott Morgan, about the “how” of poisoning deaths. Now, we want to know why. What’s going on in the mind of someone who poisons their partner?  In this episode, Senior Investigative Reporter Anne Emerson is joined by Dr. John Delatorre, a forensic psychologist specializing in partner violence. He lays out five psychological factors in intimate partner poisonings and offers his expert opinion on the Kouri Richins case as the trial presses on.  Subscribe, like, and follow Criminally Obsessed for ongoing coverage and expert insight into the cases everyone is talking about.  Make sure to follow us across all platforms for exciting announcements about CrimeCon Vegas coming soon!
