The young children of grief author Kouri Richins have begged a judge to never let her walk free from prison after she fatally poisoned their father, voicing fears that their lives and those of their family members could be in danger.

In heartbreaking letters to Judge Richard Mzarik on the eve of their mother’s sentencing, Richins’s three sons, now aged 13, 12 and nine, said they are terrified of the 35-year-old as they revealed chilling new details about the night she murdered their dad.

‘If she got out I would be so scared,’ the youngest child, who was just five when he lost his dad, said.

‘Once she is gone, I will feel happy and I will feel safer and relaxed and trust people more. She took away my dad.’

Richins killed her husband, Eric Richins, by giving him a Moscow Mule cocktail laced with a lethal dose of fentanyl at the family home in Kamas, Utah.

For more than a year, the real estate agent then played the grieving widow, publishing a children’s book titled Are You With Me? and even appearing on local TV to promote it and share her seemingly heartbreaking story of navigating grief with their sons.

But in May 2023, the facade crumbled and Richins was arrested and charged with Eric’s murder.

In an explosive trial this March, jurors heard how the realtor had been motivated by a desire to get her hands on Eric’s $4 million estate and to escape their marriage in order to start a new life with her handyman lover
