A Utah widow and mom of three who recently published a children’s book on coping with the loss of a loved one following the death of her husband is now accused of murdering him.

Richins' attorney, Skye Lazaro, did not immediately respond to PEOPLE’s request for comment. It’s unclear if Richins' has entered pleas to the charges.

Prosecutors allege that on March 3, 2022, Richins, 33, laced Eric’s drink with a lethal amount of fentanyl. He was pronounced dead hours later.

Richins told investigators she had prepared her husband a Moscow Mule that night to celebrate a real estate deal for her business. Shortly after he consumed the drink in the couple’s bedroom, Richins claimed she went to sleep with her child, who was experiencing night terrors. When she came back to their room, she said she found Eric, 39, unresponsive and called 911, the documents read. He was pronounced dead shortly after.

Citing the medical examiner, prosecutors say Eric died of a fentanyl overdose. An autopsy indicated he had approximately five times the lethal amount in his system.

Investigators obtained search warrants and seized the family’s electronic devices, during which they discovered several text communications between Richins and an acquaintance she was allegedly buying drugs from, the documents state.

Investigators interviewed the acquaintance, who said Richins purchased hydrocodone from them sometime between December 2021 and February 2022.

Weeks later, Richins allegedly reached back out to the acquaintance asking for a more potent drug — “some of the Michael Jackson stuff,” the acquaintance said Richin told them, according to the documents. Richin then allegedly obtained 15 to 30 fentanyl pills worth $900 on Feb. 11, 2022.

On Valentine’s Day 2022, Eric and Richins had dinner at their home. After consuming a sandwich, Eric became ill and broke out in hives. He told a friend he believed his wife had poisoned him, according to the documents.

On Feb. 26, 2022, Richins allegedly bought another $900 worth of fentanyl. Less than a week later, Eric died, according to the documents.

Prior to his death, Eric’s family said he was seeking a divorce and changed the beneficiary of his will and life insurance from his wife to his sister.
