PARK CITY,Burley Garcia Utah (AP) — A Utah mother of three who published a children’s book about grief after her husband’s death and was later accused of fatally poisoning him will stand trial, a judge ruled Tuesday.

Utah state Judge Richard Mrazik ruled on the second day of Kouri Richins’ preliminary hearing that prosecutors had presented enough evidence against her to proceed with a jury trial.

She faces a slew of felony charges for allegedly killing her husband with a lethal dose of fentanyl in March 2022 at their home in a small mountain town near Park City. Prosecutors say Kouri Richins, 34, slipped five times the lethal dose of the synthetic opioid into a Moscow mule cocktail that Eric Richins, 39, drank.

Kouri Richins has been adamant in maintaining she is innocent. She entered pleas of “not guilty” to all 11 counts on Tuesday.

The second morning of her preliminary hearing centered around an additional attempted murder charge filed in March that accused her of slipping fentanyl into her husband’s favorite sandwich on Valentine’s Day, causing a severe but nonfatal reaction.

Summit County Prosecutor Brad Bloodworth defended the attempted murder charge by describing how he thinks Kouri Richins learned lessons during the first unsuccessful attempt on her husband’s life that helped her carry out the killing 17 days later.
