ELKHORN – It was a very busy day of testimony at the wife poisoning trial in Walworth County. Several people took the stand, each testifying they had a different reason to believe Mark Jensen killed his wife. Two people testified they believed Mark Jensen wanted his wife Julie dead. Another said Jensen planned to hire a hit man to get rid of a key witness. Bernard Bush is a lifelong criminal, who faces 400 more years in prison. He wore handcuffs while swearing to tell the truth about his former cellmate Mark Jensen. Bush testified while inside the Kenosha CountyJjail, Jensen talked openly about his case, and how he wanted to pay someone to temporarily get rid of Ed Klug. "He asked me a while after that if it's possible to make things happen like that," Bernard Bush said. Klug's testimony put Jensen behind bars. He was out on bail before that. Klug told investigators that after a night of drinking, Jensen admitted he wanted to kill his wife Julie. Klug's former co-workers testified he told them about the conversation. "He was in a bar one evening, and they had had a conversation, and the wording may not be exact, about doing away with spouses," Quinn Yorton, who worked with Klug said. "What did you say when you heard that Julie Jensen was dead?" "I said ‘oh, my God, he killed her,’" Stacey Bauer, who worked with Klug said. The defense says Ed Klug made the story up to get attention. Several co-workers testified earlier in the trial that he was an attention seeker. As for Bush, the defense says since he faces 400 years in prison, testifying to help the prosecution is a good way to get a reduced sentence.
