Annissa Ellen-Williams, 25, was found dead outside a vehicle on the 100 block of Presidential Boulevard in Oswego on February 18, 2023, after Oswego police responded to a call at about 6:56 a.m. She was discovered lying on the ground with a gunshot wound to the head. Officers and paramedics rendered aid, but she was pronounced dead at the scene. A forensic autopsy the next day preliminarily confirmed a gunshot wound to the head; final autopsy results were pending toxicology and further investigation.

Initial information to police suggested Ellen-Williams had shot herself while driving, but investigators with the Oswego Police Department and the Illinois State Police later determined the manner of death to be homicide. A 26-year-old woman from the same address, Alexis Telles, has been charged with three counts of first-degree murder, two counts of aggravated battery of a peace officer, and one count of unlawful possession of a weapon by a felon. Telles is being held in the Kendall County Jail with bail set at $3.04 million, 10 percent applicable for bond. Authorities continue to investigate and are asking anyone with information to come forward.

Did anyone in Oswego or the surrounding area see or hear anything that morning that could help the investigation?
