During “Season One: Where Is Karen?” Detectives Andrew Houghton and Matt Vartanian researched the previous tenant of Karen Schepers’ apartment, Thomas Urlacher.  They found that while he was not involved in Karen’s disappearance, he was the prime suspect in the disappearance of 14-year-old Barbara Glueckert from nearby Huntley, Illinois on August 21, 1976. In Part 1 of this two-part investigation, Detectives Andrew Houghton and Chris Hall from the Elgin Police Department Cold Case Unit discuss Urlacher’s links to Karens’ case and meet with Barbara Glueckert’s family to learn about her and the impact that her disappearance has had on her family and on her community.
