The Search for Jill Rosenthal

For more than 60 years, one missing child has remained almost completely forgotten.

After uncovering his own true identity through DNA, Paul Jack Fronczak made a discovery that changed everything—he wasn't an only child. He had a twin sister, Jill Rosenthal, who vanished in 1965 at the same time he was found abandonded on a street corner in Newark, NJ and was never reported as a missing child.

In Season 5 of The Fronczak Files, Jack, Tracey and the team reopen Jill's case from the very beginning, exposing overlooked evidence, hidden family secrets, and decades of unanswered questions. Through groundbreaking genetic genealogy, historical research, and exclusive interviews, they pursue one goal:

Bring Jill home.

Meet The Hosts

Paul Jack Fronczak stands at the center of one of the most complex identity mysteries in American history. Raised as the infant kidnapped from a Chicago hospital in 1964, DNA later revealed he was not biologically related to the Fronczak family—reshaping everything he thought he knew about himself.

Instead of turning away, Jack went deeper.

His search for the truth took him across continents, through archives, and into the heart of his own origins. Along the way, he became a voice for others living with unanswered questions about identity. His books The Foundling and True Identity, along with the Emmy-nominated documentary The Lost Sons, brought his story to a global audience.

Today, as founder, host, and executive producer of The Fronczak Files, Jack blends lived experience with investigative precision and relentless curiosity. He understands that identity is more than DNA—it’s memory, culture, loss, and resilience.

His mission is simple: uncover the truth—and help others reclaim theirs.

Tracey Hastings blends clinical precision with deep compassion in every investigation. A registered nurse specializing in high-risk obstetrics, she’s spent her career in moments where lives—and identities—can change in an instant.

As co-host and associate producer of The Fronczak Files, Tracey is known for her sharp eye, relentless follow-through, and instinct for uncovering overlooked connections. She brings both analytical rigor and empathy to each case, ensuring every story is handled with care and respect.

Since joining forces with Jack Fronczak in January 2025, their partnership has quickly become a shared mission: challenge assumptions, uncover buried truths, and give voice to those lost to history.

At her core, Tracey is driven by a simple belief—everyone deserves to know where they come from, and every story deserves to be heard.
