Defense witnesses pushed two potential theories Friday on how Orland Park's Anita "Jeanie" Kustok may have been fatally shot in 2010.
Allan Kustok, 63, is on trial, accused of shooting his wife in the face with a .357-caliber revolver as she slept in their bed.
Blood spatter expert Paul Kish contradicted testimony from the prosecution's expert witness early this week, who maintains the blood spatter deposits prove Allan Kustok was standing over his wife when she was shot. Kish disputes the blood marks on Kustok's clothing and glasses was even gunshot spatter.
"You can't state to a reasonable degree of scientific certainty how they were deposited there," Kish said.
He also contradicted the prosecution's assertion that flakes of blood found in the evidence envelope had somehow fallen off Kustok's glasses.
"It's simply an unreasonableness opinion based on the facts of this case," Kish said.
The defense next called ballistics expert Matthew Noedel to the stand, who told the jury it would have been much easier for Jeanie Kustok to pull the trigger on the .357 magnum revolver if the gun was cocked first. He said that would also make it easier to trigger accidentally.
For the second straight day, the Kustok's daughter, Sarah, waited to testify at the trial. She's now expected to take the stand early next week to discuss text messages between her and her father discussing her mother's birthday.
The trial is expected to wrap up sometime next week.
