A surprise message opens a long-closed door to Jon’s secret past. Sonia Lee has been listening to every episode in the Bronwyn podcast series while weighing the right time to come forward for the first time. She made a promise to her grandmother on her death bed to tell the truth about her biological father when the time was right. A man she has never known— but is now hearing so much about. In a remarkable interview with Hedley Thomas, Sonia Lee reveals her biological father is Jon Winfield, and his then-girlfriend was 15 and left heartbroken when Jon denied being the father. He refused to help her or his baby. Bronwyn’s sister-in-law, Michelle Read, recovers an historic document from the files of the police Unsolved Homicide unit, confirming Jon’s conduct. Sonia Lee says Jon needs to stop lying. She hopes her truth can help solve Bronwyn’s cold case.  Read more about this case and see photographs, maps, timelines and more at bronwynpodcast.com.  If you have information which may help solve this cold case, you can contact our team confidentially by emailing [email protected] If you need support, Lifeline can be reached on 13 11 14.
