Episode Title Death By Antifreeze
Outwardly, Mark Jensen seemed to be a mild-mannered, loving husband -- grieving over the early December 1998 suicide death of his wife, Julie, who was found by their two young sons. But when Wisconsin police found traces of antifreeze in her autopsy, they started to question what was really going on at home. They soon discover that Mark moved another woman in a month after his wife's death.
