Illinois Mom, 43, Charged After DNA Links Newborn to 14-Year-Old From Daughter’s School Dance

She is being held without bail ahead of a Dec. 4 arraignment.

Overview

  • Robyn Polston faces two counts of criminal sexual assault of a 13–17-year-old and two counts of possession of child pornography, according to court records.
  • A probable-cause affidavit says DNA testing identified the teen as the baby's father and details a cache of explicit images and videos.
  • Investigators say the baby's birth certificate bears the teen's middle and last name and that Polston initially claimed the father was a man named “Brian.”
  • The case traces contact to a May 2023 junior-high dance Polston chaperoned, with subsequent visits in 2024 around the time of conception, per the affidavit.
  • Prosecutors told the court Polston used burner phones and tried to orchestrate a cover story, and they argued for detention to prevent contact with the minor.
