The autopsy results for a Port Charlotte man have been released. In a press release, the Medical Examiner’s Office of Florida says that 47-year-old Gregg Ireland died of natural causes on Aug. 24 while in the custody of the Charlotte County Jail. Ireland had been arrested two days earlier on DUI charges. During his detainment, he became combative with another inmate and with detention staff when they tried to relocate him to another part of the facility. During the struggle, Ireland became unresponsive. He was taken to Bayfront Hospital in Punta Gorda where he later died.
