(Sterling, IL) — The 15-year-old daughter of the woman found dead in her Whiteside County home will be tried as a juvenile for her mother’s murder. Prosecutors in Sterling yesterday filed formal charges against Anna Schroeder and her 15-year-old friend Rachel Helm. Investigators say Schroeder shot her mother, Peggy Schroeder, in the head last Thursday. They say both girls set Schroeder’s house on fire on Saturday to try and hide the murder.
