A Utah woman who authorities say fatally poisoned her husband in 2022, then published a children’s book about grief, now faces another attempted murder charge for allegedly drugging him weeks earlier on Valentine’s Day.

Kouri Richins, 33, is accused of killing her husband with a lethal dose of fentanyl at their home in a small mountain town near Park City in March 2022. New charging documents filed Monday by Summit County prosecutors allege that was not her first attempt on his life.

They detail the perilous months preceding Eric Richins’ death, painting a picture of a paranoid man walking on eggshells around his wife as she made secret financial arrangements and bought illicit drugs that were later found in his system.

Prosecutors have said previously that Kouri Richins, who is being held without bail, may have tried to poison her husband the month before his death, but they did not file the additional charges until this week.
