Description

Mysteries, DNA, and the Search for Who We Really Are.


The Fronczak Files is a gripping podcast that delves deep into the investigation of the abduction of Paul Fronczak, the abandonment of Jack Rosenthal, and the disappearance of Jack’s twin sister Jill. This true crime podcast takes you on a rollercoaster ride through Paul’s experiences, searching for his family and uncovering new mysteries along the way. In April 1964, a woman disguised as a nurse walked into a Chicago hospital room and took a one-day-old infant from the arms of a young mother named Dora Fronczak. That day, Chicago police kicked off the biggest manhunt in the city's history in an effort to find the kidnapped "Baby Fronczak." Weeks passed without any sign of the kidnapper or the infant. Two years after the kidnapping, the case went cold… Co-hosted by Paul Jack Fronczak and Tracey Hastings, Season 1 pulls you into the decades-long search for answers, identity, and justice. No theories. No holding back. Just the raw, unfiltered truth - told straight from the source.
