An author who wrote a children’s book about grief after her husband’s death has been found guilty of murdering him. Kouri Richins, 35, was convicted of killing her husband Eric, 39, by serving him a fentanyl-laced Moscow Mule, a Utah court heard. A medical examiner found Mr Richins had five times the lethal dose of the drug in his system. The following morning, Richins called emergency services in a panic, saying: "My husband's not breathing. He's cold". TRENDING Stories Videos Your Say A year later, she published a children’s book titled "Are You With Me?", about the "difficult experience of losing a loved one". Prosecutor Brad Bloodworth told the court Richins had begun plotting her husband’s death months earlier. Jurors heard she wanted a fresh start with her boyfriend Robert Grossman and had taken out multiple life insurance policies on her husband. Her business was also millions of dollars in debt. Prosecutors said she had initially planned to kill him using a fentanyl-laced sandwich. In October 2021, she booked a holiday with Mr Grossman - a trip she arranged knowing Eric Richins would be dead, the court heard. Months before his death, Richins texted Mr Grossman: "We both know this love triangle can’t go on forever. You don’t deserve it, I don’t deserve you. I can’t expect you to sit around for the day the trigger gets pulled," In early 2022, she contacted her former housekeeper, Carmen Lauber, asking for medication for back pain.

She asked for "some of the Michael Jackson stuff". Ms Lauber later obtained fentanyl and sold it to Richins for $900 (£674) on February 11, before later telling police. Two weeks before the fatal poisoning, Richins allegedly tried to kill her husband with a sandwich left "on the seat of his truck with a love note," according to court filings. Mr Richins ate the sandwich and suffered hives and breathing difficulties, but managed to inject himself with his son’s EpiPen. He later told a friend he believed his wife was trying to poison him, the court heard. Five days after that incident, Richins texted Mr Grossman: "If he could just go away and you could just be here! Life would be so perfect!!!" She then messaged Ms Lauber for more fentanyl pills, asking her to leave them at an outdoor fire pit. Six days later, her husband was dead. In April 2023, Richins appeared on local television to discuss her book, saying that although her husband was not "with us physically, that doesn't mean his presence isn't here with us". "Dad is still here, it's just in a different way," she said - just one month before she was arrested and charged with his murder. "This book is a killer!" a reviewer wrote on the book's Goodreads page shortly after her arrest. Richins now faces a maximum sentence of life in prison and is due to be sentenced on May 13.
