Robyn Polston was a 43-year-old mom and hairdresser from Washington, Illinois. Police say that same mom is now behind bars after allegedly giving birth to her daughter’s 14-year-old boyfriend’s baby. According to investigators, Robyn Polston carried on a secret relationship with the teenager for more than two years. They say she even posed for a maternity photoshoot with him, told friends a series of conflicting stories about who the baby’s father was, and tried to keep the truth buried until a DNA test revealed everything.
