LA CROSSE, Wisconsin (WXOW) - Testimony in the Eric Koula trial is over.
Shortly after 10am Friday morning, both the defense and prosecution finished presenting witnesses.
Koula is on trial for killing his parents Dennis and Merna Koula in their Barre Mills home in May, 2010 in order to collect on an inheritance according to prosecutors. The defense has argued that the shootings were a "professional hit" possibly targeting a neighbor, but that the killer ended up in the wrong home.
The sole witness called Friday was Robert Morton of the FBI. He works at the National Center for the Analysis of Violent Crime. Based on his experience, there is nothing to show Dennis and Merna were killed by a professional assasin.
"Do you have an opinion whether the lack of forensic evidence, such as fingerprints, DNA, or a bullet match, indicates that this person was an experienced killer?" asked Prosecutor Gary Freyberg, of the Wisconsin Department of Justice.
"No it does not. There are a number of ways that people can receive instructions on doing that, one of which is very commonly called the CSI effect," Morton said.
"You can watch TV and learn about how police process evidence and which evidence they process," he added.
According to Judge Scott Horne, the jury will hear closing arguments and receive their instructions on Monday. He also held the jury until the Clerk of Courts could come in and go over the rules of sequestration.
Once they begin deliberations, jurors will not have any outside contact except through deputies and court staff until a verdict is reached.
