Utah has never executed a woman or had a woman on death row, but that could change after Sunday night's murder in suburban Salt Lake City.

Chelsea Watrous Cook, 32, has been charged with aggravated murder in the shooting of Lisa Vilate Williams, 26, and could face the death penalty, Deseret News reports.

Police say the teacher lured ex-husband Travis Cook out of his apartment by saying she had cold medicine for one of their 3-year-twins, reports the AP.

Security camera footage captured her hiding in the hallway as he walked out to the parking lot. Police say she then sneaked into the apartment, where she ended up shooting Williams, her ex-husband's new girlfriend, who had been making Christmas tree ornaments with the twins.



Authorities say Travis Cook managed to get the gun away from his ex-wife and pin her to a wall until police arrived. Williams' mother and sister tell the AP that they feared for her safety after Cook harassed her and bullied her online for months.

Public records state that Cook was charged with misdemeanor domestic violence last month after arguing with her ex-husband when he tried to pick up the twins.

Court records state that she yelled "disparaging comments" about Williams, who was not present, and grabbed her ex-husband by the hair, causing him to tumble down stairs.

Cook, who worked as a health and yoga teacher at a Lehi high school, is being held without bail.
