Kouri Richins, a Utah woman who authored books on grief after her husband's death, was convicted of aggravated murder on Monday. The jury deliberated for about three hours before finding her guilty of poisoning her husband Eric Richins with a lethal dose of fentanyl in March 2022.

The prosecution presented evidence that Richins mixed the drug into a Moscow Mule cocktail served at their home outside Park City, Utah. Prosecutors alleged that she was motivated by financial troubles, citing $4.5 million in debt and her desire to leave Eric but not his money. According to prosecutors, Richins was also planning a future with another man.

Richins faced additional charges of attempted murder for allegedly poisoning her husband weeks earlier on Valentine’s Day with a fentanyl-laced sandwich that made him break out in hives and black out. She was also found guilty of fraudulently claiming insurance benefits after his death, as well as mortgage fraud and forgery related to a multimillion-dollar real estate deal signed the day after her husband's death.

The most serious counts against Richins carry maximum sentences of life in prison. Sentencing is scheduled for May 13, the day Eric would have turned 44. Throughout the trial, Richins maintained her innocence, with her defense arguing that prosecutors failed to prove she was responsible for the fatal dose of fentanyl found in his system.

Prosecutors revealed that Richins had opened numerous life insurance policies on her husband without his knowledge, with benefits totaling about $2 million. Text messages between Richins and Robert Josh Grossman, the man with whom she was allegedly having an affair, showed her fantasizing about leaving her husband, gaining millions in a divorce, and marrying Grossman.

Richins stared at the floor and took deep breaths as the judge read the verdict. Family members on both sides of the case left the courtroom hugging and crying after the jury's decision was announced. Eric Richins’ sister, Amy Richins, expressed shock but stated that the family could now focus on honoring her brother and supporting his sons.

In promotional interviews with local media, Richins said she had written a children's book about coping with grief called Are You With Me? with her kids. She told NPR member station KPCW in April 2023 that the process 'brought a little peace to me and my boys.' Weeks later, Richins was charged with killing her husband.

The defense attorney argued that Eric had Lyme disease and was addicted to painkillers, calling the investigation into his death 'nothing but sloppy' and 'driven by bias'. Prosecutors painted Kouri as an 'intensely ambitious' but 'incompetent' business owner who projected affluence even as she fell deeper and deeper into debt.

Prosecutors said that Richins had taken out multiple life insurance policies on her husband while having an affair. She was also litigating property issues with Eric's family in civil court, according to KPCW reports.
