Court records allege that a Utah woman who wrote a children's book about grieving after her husband's death poisoned him with fentanyl.

Kouri Richins, 33, is facing charges of aggravated murder for the death of her husband, Eric Richins, 39. He was found dead on March 4, 2022, at the foot of their bed.

Kouri had recently promoted her children's book on a television show, claiming that her husband had passed away unexpectedly. However, prosecutors allege that Eric was poisoned with fentanyl the night before his death, according to ABC News.

Before her husband's death, Kouri Richins had reportedly asked an acquaintance for "some of the Michael Jackson stuff," referring to propofol, which was found in Michael Jackson's system when he died in 2009. The acquaintance provided her with dozens of fentanyl pills, the court document said, NBC News reported.

Kouri Richins claimed that she had made her husband a drink that he consumed before she went to sleep with their child. She said that when she returned to their room, she found him unresponsive and tried to perform CPR. However, first responders found no evidence of CPR and noted a significant amount of blood in Eric's mouth.

Kouri Richins' cellphone was later found to have been locked and unlocked several times, with text messages being sent and received that had been deleted.

The suspect published a children's book about grief almost a year after her husband's death. It was described as "heartwarming and reassuring."

The book, titled "Are You With Me?", follows the story of a child who has lost his father and is reminded that his presence still exists all around him, per The Straits Times.

Richins' charges come less than a year after a woman who penned a tract titled "How to Murder Your Husband" was arrested.

Nancy Crampton Brophy shot her husband twice at the Oregon culinary school where he was employed to collect hundreds of thousands of dollars in life insurance.
