A 43-year-old woman from Illinois has been arrested and charged with two counts of criminal sexual assault and two counts of possession of child pornography, following the birth of a child she allegedly conceived with a 14-year-old boy. The boy, who was reportedly the date of the woman’s daughter at a junior high dance, is believed to be the father of the child, according to law enforcement officials.
The woman, identified as Robyn Polston, was taken into custody on Monday morning. The arrest came after an investigation was launched by the Washington Police Department in response to a complaint received after Polston gave birth in January 2025.
The investigation led to the discovery of the baby’s birth certificate, which revealed that the child’s name matched the middle and last name of the alleged victim. Polston had previously told police that the father of the newborn was a man in his twenties named Brian, with whom she had severed ties after the birth.
Further investigation revealed that the alleged victim and Polston’s daughter had attended a junior high dance together in May 2023, where Polston was a chaperone. The boy had moved away but returned for a visit 40 weeks before the child’s birth in April 2024. He then moved back to the area in August 2024 to live with the family of a friend.
Phone records obtained during the investigation allegedly revealed a collection of sexually explicit images and videos of Polston and the teenager. It was also discovered that Polston and the 14-year-old used burner phones under fake names to conceal their identities. Polston is also accused of attempting to coerce the boy into participating in a cover-up.
A DNA test confirmed the alleged victim as the baby’s father. Prosecutors argued that Polston could not be trusted to cut contact with the father of the child, alleging that Polston’s mother and sister were complicit in the inappropriate relationship.
Polston has been ordered to be held without bail while her case is pending. Her attorney has not responded to requests for comment. Polston’s next court appearance is scheduled for December 4.
