Summary
This source details the criminal case of Mark Jensen, a Wisconsin man convicted of murdering his wife, Julie Jensen, by poisoning her with antifreeze. While the defense argued that Julie’s death was a suicide driven by depression, prosecutors presented evidence of Mark’s long-term psychological torture and his desire to replace her with his mistress. Key evidence included incriminating internet searches for toxins and a letter written by the victim before her death expressing fear that her husband would kill her. Although the initial conviction was overturned due to constitutional disputes regarding that letter, a second trial resulted in another guilty verdict without it. Ultimately, the court sentenced Mark to life in prison without parole, rejecting his claims of innocence. The case highlights the tragic impact on the couple's two sons, who spent decades believing their mother had abandoned them by choice.
