Peoria, IL – A 39-year-old female detainee at the Peoria County Jail was found unresponsive in her cell early Tuesday morning, prompting emergency life-saving efforts that were ultimately unsuccessful, according to officials.
According to the Peoria County Sheriff’s Office, correctional officers discovered the woman at approximately 4:25 a.m. on December 9, 2025. Officers began resuscitation attempts immediately and called for additional medical assistance. Emergency crews from AMT and Limestone Fire responded and continued efforts, but the woman was pronounced deceased at the scene.
The Peoria County Coroner’s Office arrived shortly after the incident. Officials stated the detainee had been booked into the jail on December 7 on a failure-to-appear warrant. Her name has not been released pending family notification.
According to investigators, there are currently no preliminary signs of foul play. The Illinois State Police and the Peoria County Coroner’s Office are leading the investigation, which will include autopsy results and a full review of the woman’s time in custody. Officials noted that additional details will be released as they become available.
The Sheriff’s Office did not provide information regarding the woman’s medical history or whether she had shown any prior signs of distress. In-custody deaths, while uncommon, typically trigger multi-agency reviews to determine cause and evaluate procedures in place.
Residents in Peoria County and the surrounding central Illinois region are encouraged to follow official updates as investigators continue to gather information.
