(KUTV) — A Skyridge High School teacher is accused of shooting and killing her ex-husband’s girlfriend, according to a probable cause statement.

32-year-old Chelsea Cook is facing a possible aggravated murder charge for shooting and killing 26-year-old Lisa Williams, her ex-husband’s girlfriend.

2News confirmed through Alpine School District that Cook was a teacher at Skyridge High School.

The shooting happened Sunday night around 6:58 p.m. at the Station at Midvale apartments at 7960 South Center Square in Midvale.

Unified Police initially responded to the incident, but Salt Lake City police later took over the investigation because one of the persons involved is related to a Unified Police Department employee.

The name of the witness has not been released by police.

The ex-husband told officers that Cook, his ex-wife, stopped by the apartment to deliver cold medicine to one of their children.

2News has confirmed Cook is a teacher at Skyridge High School in Lehi.

Cook entered the apartment while her ex was in the parking lot. She was told to leave, according to police, but refused.

Cook’s ex-husband says she then locked herself in the bathroom. Emergency crews were called at this time.

Cook later exited the bathroom to grab her coat before suddenly pulling out a handgun and firing three to five shots at Williams, according to police.

Williams fell back and landed on the couch.

Cook and her ex-husband’s two 3-year-old twins witnessed the entire ordeal.

The ex-husband was then able to wrestle the handgun away from Cook, who then sat on a chair with her two twins, while her ex attempted to help the victim.

The probable cause statement says Cook then walked back over to grab her coat when her ex-husband grabbed her and pinned her against the wall until officers arrived.

Cook was taken to the Salt Lake County Jail, where she is facing one charge of aggravated murder.
