On October 28, 1991, an anonymous man called 911 and directed emergency crews to a home in Wheeling, Illinois. He gave Jamie Santos’s exact address, said a young woman inside was not breathing and “turning blue,” then disconnected when dispatchers asked when he had been at the house. Jamie was 27 years old. She could not be revived. More than three decades later, her murder remains unsolved—and the caller has never been publicly identified. In this episode of The Grimes Files, Joey Grimes reconstructs the 911 call, the emergency response, and the investigation that followed. We examine reported voice-recognition claims, the nearby surveillance lead, conflicting public accounts of the scene, and physical evidence retested decades later with results that have not been publicly released. If you have information about Jamie’s murder or the anonymous 911 caller, contact the Wheeling Police Department Investigations Division. If you believe you recognize the voice, provide that information directly to investigators. Do not publicly name a private person.
