IOWA CITY, Iowa — The Iowa Division of Criminal Investigation is looking into the death of an inmate in the Johnson County Jail after an apparent medical emergency last week. According to a release from Johnson County Sheriff Brad Kunkel, 36-year-old Nathaniel Davis Jr. was booked into the jail on March 10 to serve a seven-day sentence. On March 14 at approximately 6:10 p.m., Davis had an apparent medical emergency, and a deputy watching a camera monitor saw Davis fall over in his cell. When jail staff responded to Davis’ cell and determined he was having a medical emergency, they began CPR and applied an automatic external defibrillator. An ambulance was also called at this time.

Davis was transported to University of Iowa Hospital, where he died on March 19. According to Kunkel’s release, his office has requested the DCI investigate the incident. An autopsy will be conducted by the Johnson County Medical Examiner’s Office and the State Jail Inspector has been notified.
