48-year-old Kathleen Mohn was last seen at her home in the Gulph Mills section of Upper Merion Township, Pennsylvania on the evening of December 3, 1999. Kathleen had intended on spending the weekend in Levittown, Pennsylvania, just about a 40 minute drive from her home. At this time in her life, Kathleen was living with her husband, Thomas Mohn. After over 20 years of marriage, the two had become estranged and had begun openly seeing other people, but they still remained living under one roof. Kathleen had spent most weekends with her boyfriend in Levittown and this weekend in early December was no different. Her husband has said that she left the house around 9PM that evening but she never made it to her destination and her car was later found abandoned in Tullytown, PA.For the past 19 years, the police have had one suspect in mind, but their evidence is circumstantial. What they are certain of is that Kathleen didn’t just walk away from her life, the believe that she is a homicide victim. They just need that key piece of evidence to bring her killer to justice.If you have any information about the disappearance of Kathleen Mohn please call the Upper Merion Police Department at 610-265-3232.This episode was co-researched and written by Marissa Jones and Erika Gwynn.
