NEVADA, Iowa -- Alexander Kozak's defense rested its case Friday without calling the 23-year-old defendant to the stand. Kozak is on trial for the first-degree murder of 20-year-old Andrea Farrington at Coral Ridge Mall in Coralville.
Kozak's attorney, Alfredo Parrish, called for a mistrial for the second time, but the judge denied the motion.
While the jury never heard Kozak testify on the witness stand, police recordings were played that captured Kozak describe a "cold fury" that came over him when he pulled the trigger on June 12.
The defense called a psychiatrist to the stand Thursday, who said Kozak suffered from two mental conditions that caused him to snap on the day of the shooting: Intermittent explosive disorder and borderline personality disorder. The two combined would send Kozak into a rage where couldn't think or control his emotions.
The state called its own psychiatrist to the stand Friday who evaluated Kozak and testified that he does not suffer from any psychiatric diagnosable disorder, but he did note that Kozak showed signs of low empathy.
“He had no psychiatric diagnosable disorder. He had some vulnerabilities being perhaps lower in empathy, the ability to appreciate how his behaviors might affect others, but he had no psychotic disorder,” said Dr. Arnold Andersen.
The state psychiatrist said Kozak was up front, intelligent and imaginative when describing his actions last June. Andersen said he's treated hundreds of patients and most of them who suffer from mental illness tend to harm themselves not others.
Following his evaluation, Andersen said Kozak does not have schizophrenia, bipolar or any other mood disorder. He said he believes Kozak was in his right mind during the shooting.
The state also called Dr. Tim Kockler to the stand. He a licensed psychologist in several states and does evaluations for criminal cases. Kockler said Kozak described his anger as a "volcano."
"He was seething, seething mad. To use his own terms, it was the volcano. He seemed to be getting more angry as the day progressed," Kockler said.
Kozak reportedly told Kockler that he and Farrington loved each other.
“He described it as an emotional affair. He also called it an interesting relationship,” Kockler said.
The state's expert agreed with part of the defense's evaluation that Kozak suffers from a personality disorder.
“I’m just saying he has a hodge podge of personality issues.”
But Kockler said Kozak doesn't fit the bill of someone with intermittent explosive disorder. With that, experts see a criminal history of violence. Up until the shooting, Kozak only had a speeding ticket.
Kozak showed no signs of hallucinations or hearing of voices. He also did not have a drug or alcohol problem.
Closing arguments in the first-degree murder trial are set for Monday at 9:30 a.m. in Story County.
