Both Kozak and Farrington had been employees at Coralridge Mall. The two had been friends for a while and shared a flirtatious relationship for a while. However, Farrington later felt unsafe within this relationship and began filing complaints of harassment and threats to their employer. Kozak was eventually fired on the evening of 06/12/15. He went home and returned with the weapon that he used to killed Farrington.
Kozak's trial was relocated to Story County, IA. The trial went from April 14th and lasted through today. There was no question about whether or not Kozak killed Farrington. He admitted as much. His defense team tried to mitigate the level of his responsibility by pointing out his diagnosis of intermittent explosive disorder and borderline personality disorder. (Jon's Note: I know way too many people with borderline personality disorder. This is a personality disorder that does not take away your ability to understand your actions. But the other diagnosis is an interesting defense, IMHO.)
His legal defense wasn't enough to protect Kozak from conviction. He was convicted of one count of first-degree murder earlier this afternoon. This carries a mandatory life sentence here in Iowa.
