ELKHORN - Julie Jensen told police that if she died, her husband Mark should be their first suspect. Thursday, the officer she confided in took the stand. The officer testified he received several very disturbing voicemail messages from a distraught Julie Jensen. "There was a second message from Julie Jensen, and that I should call her, and that if she were to end up dead, that Mark should be her first suspect," Pleasant Prairie Police Department Officer Ron Kosman said. The disturbing phone messages weren't officer Ron Kosman's first dealings with the Jensens. He had responded to calls at the Jensen’s home several times before, after harassing phone messages and pornographic pictures were repeatedly left at the Jensen home. An investigation led Kosman to believe Mark Jensen left both the messages and the pictures to get back at his wife for having an affair years earlier. Kosman told Julie to leave her husband, but she wouldn't. Attorney Craig Albee: "When you asked her numerous times to leave, she backed off on her level of fear, correct?" "Correct," Officer Ron Kosman said. The defense says she never left because she was never in danger. Another officer testified about police videotape taken inside the Jensen home the night Julie died. Lieutenant Dan Reilly says just after Julie’s death a very distraught Mark Jensen told him Julie was depressed and was having suicidal thoughts. Attorney Craig Albee: "He was visibly upset?" "Yes, he was visibly upset," Lieutenant Dan Reilly said. The defense says the fact that Mark Jensen was very upset the night his wife died proves that she killed herself. The state says he murdered her.
