S4E4 Death By Antifreeze

Mark Jensen appeared to be a gentle and devoted husband, mourning the tragic suicide of his wife, Julie, in early December 1998, a loss witnessed by their two young sons. However, when Wisconsin authorities detected traces of antifreeze during her autopsy, suspicions arose about the true circumstances surrounding her death. Investigations revealed that just a month after Julie's passing, Mark had already moved another woman into their home.
