The death of an inmate at the Cerro Gordo County Jail in Mason City is under investigation.

The Iowa Division of Criminal Investigation says a man was found unresponsive in a detox cell at about 4:25 Thursday morning. According to the DCI’s written statement, jail staff attempted to perform life-saving measures and Mason City fire paramedics took the man to Mercy Medical Center-North Iowa, where he was pronounced dead.

The inmate’s name was not released. An autopsy has been scheduled at the State Medical Examiner’s Office in Ankeny.
