Murder of Julie Jensen

The Julie Jensen case involves the trial of a Pleasant Prairie, Wisconsin man, Mark Jensen, on charges that he murdered his wife, Julie Jensen on December 3, 1998. The case is notable for the eventual admission into evidence of a letter written by the deceased prior to her death expressing suspicion of her husband's intentions.
Julie Jensen investigated her husband, checked his planner, photographed a note, and documented her suspicions. She gave the letter to a neighbor with instructions to hand it to police if anything should happen to her. She wrote that she would never commit suicide and that if she died, police should consider her husband a suspect. "I pray that I am wrong and nothing happens, but I am suspicious of Mark's suspicious behaviors and fear for my early demise."
In 2008, Mark Jensen was convicted of first degree murder and sentenced to life imprisonment without the possibility of parole, a verdict which was later overturned.
Background.
Julie Griffin was working at a Sears department store in Oshkosh when she met Mark Jensen in 1981. Both were students at a local college; Mark graduated but Julie did not. The couple moved to the Carol Beach neighborhood of Pleasant Prairie, Wisconsin and had two children, David and Douglas, aged 8 and 3 at the time of Julie's death. Julie was described as having a complicated family life (her mother was an alcoholic and her younger brother died in an accident as a toddler), but was a devoted mother to her children. At the time of her death, Julie worked a part-time job for the Port Authority in Chicago, while Mark Jensen was employed at a construction firm.
Trial.
Special Prosecutor Robert Jambois contended that Mark Jensen poisoned his wife Julie, then 40, with ethylene glycol (antifreeze) and then suffocated her inside the garage of their home in Pleasant Prairie on December 3, 1998. The trial was moved from Kenosha County to Walworth County in response to pre-trial publicity. Defense counsel Craig Albee argued that Julie Jensen was a depressed woman who killed herself and framed her husband. Moreover, the deceased had seen a therapist at least three times for depression and was aware of her husband's extramarital affair with a co-worker, Kelly LaBonte Grieman, whom Mark Jensen later married, and who assumed custody of the Jensens' two sons after Mark's eventual imprisonment. Evidence was introduced showing that Mark Jensen had discussed poisoning his wife with co-workers and a jailhouse associate, as well as searching on the internet for information relating to spousal murder and poisoning techniques. The prosecution contended further that Jensen remained angry over his wife's brief affair in 1991 with co-worker Perry Tarica. The letter's use by the prosecutors was controversial, because such evidence has been blocked from court for years by strict hearsay rules based on criminal defendants' rights to confront their accusers under the Sixth Amendment to the U.S. Constitution. But the Wisconsin Supreme Court, guided by a U.S. Supreme Court ruling (Crawford v Washington 541 U.S. 36 (2004)), held that the use of Julie Jensen's letter and statements could be admitted based on the "forfeiture by wrongdoing" doctrine, under which a defendant waives his right to confront a witness if he caused the witness to be absent.
The letter was the critical factor in the trial that ended on February 22, 2008. The jury found Jensen, 48, guilty of his wife's murder after more than 30 hours of deliberations. He was sentenced by Kenosha County Circuit Court Judge Bruce Schroeder on February 27, 2008, to life in prison with no chance of parole.
Appellate proceedings.
On December 19, 2013, a federal judge overturned Jensen's conviction, and ordered he be released from prison within 90 days. The court agreed with Jensen's argument that the state's use of his dead wife's words violated his Constitutional right to confront witnesses testifying against him. The state of Wisconsin appealed the case, but in 2015 the United States Court of Appeals for the Seventh Circuit upheld the district court's decision on September 8, 2015.
Prosecutors decided to retry Jensen for the murder of his wife in January 2016. On September 1, 2017, Kenosha Circuit Judge Chad Kerkman reinstated Mark Jensen’s conviction. On February 26, 2020, Wisconsin's Court of Appeals, District II, issued a summary disposition reversing Judge Kerkman's decision to reinstate the conviction. The matter is remanded to the Circuit Court for further proceedings including trial. Evidence contained in Julie Jensen's letter and voicemail will not be admissible.
