A jury has found Alexander Kozak, 23, guilty of first-degree murder after shooting Andrea Farrington in the back three times on June 12, 2015. His sentencing hearing will take place later this year. He faces life in prison without parole.

The prosecution and defense lawyers finished up closing arguments today in Nevada, Iowa, where the trial was being held due to the high-profile nature of the case. The jury deliberated for roughly one-and-a-half hours.

Kozak has pleaded not guilty and submitted a diminished-responsibility defense, contending that he suffered from a mental defect.

Farrington, a 20-year-old employee at the Iowa Children’s Museum in the mall, was working the museum’s information kiosk at around 7:30 p.m. on June 12 when Kozak shot her three times in the back before fleeing. Kozak had formerly worked a security guard in the mall.

Kozak, a former North Liberty resident, was captured on I-80 the next morning.

Kozak has pleaded not guilty and submitted a diminished-responsibility defense, contending that he suffered from a mental defect. Alfredo Parrish is representing him.
