On the evening of June 12, 2015, 20-year-old Andrea Jean Farrington was working at the Iowa Children’s Museum kiosk in the Coral Ridge Mall in Coralville, Iowa, when a former mall security guard, 22-year-old Alexander Kozak, approached her. Farrington had reported prior unwanted attention from Kozak, telling family he would stare at her at work and had left notes on her car; she had also reported his harassment to mall authorities and had sent him texts ending their relationship.

According to authorities, Kozak left the mall, went to his residence to retrieve a 9mm Glock, returned to the kiosk and shot Farrington three times in the back. Shoppers and employees attempted to help her; she was taken to a nearby hospital and pronounced dead. Kozak fled but was stopped on Interstate 80 about 50 miles away and confessed, saying he had returned with the gun to shoot her. He was arrested and charged with first-degree murder.

If anyone knew Andrea, her routines at the mall, or saw anything unusual at Coral Ridge Mall that evening, please share information with investigators.
