Christopher Green was arrested Aug. 9 and had been held without bond at the detention center, according to the sheriff's office. Court records show he faced charges including possession of a stolen firearm, discharging a firearm into an occupied property, and carrying a concealed weapon, among others.

Green was taken to a nearby hospital on Oct. 29 following what the sheriff's office described as a requested medical screening. Officials did not say who requested the screening or why. The sheriff's office indicated that additional details about Green's health may not be disclosed because they are protected under the Health Insurance Portability and Accountability Act.

The cause of death was not immediately known, and the medical examiner's office is working to determine it. The sheriff's office did not explicitly state where Green died, though the circumstances suggest he died at the hospital rather than at the detention center.

"On behalf of the Mecklenburg County Sheriff's Office, I extend our deepest condolences to Mr. Green's family and loved ones during this incredibly difficult time," Sheriff Garry McFadden said in a statement. "We recognize the profound loss they are experiencing, and I am grateful they were able to be by his side in his final moments."

Green's death is the latest in a series of fatalities at the county jail that have drawn attention from advocates, attorneys and investigators. More than 20 people have died at the facility since McFadden took office, according to prior reporting. Earlier this year, the sheriff attributed the string of deaths to overcrowding, a health care crisis and illegal drug contraband.

Federal lawsuits filed in recent years have alleged "deliberate indifference" in medical care and failures to properly monitor inmates at the Mecklenburg County jail. Some of those cases have been settled. One lawsuit filed in October alleged that an inmate had toes amputated after what the complaint described as medical neglect.

For families with loved ones in custody and for community members tracking conditions inside the jail, Green's death raises familiar questions about how medical needs are identified and addressed behind bars. The sheriff's office has not said whether any internal review will follow, and it remains unclear when the medical examiner will release a cause of death.

Green's family could not immediately be reached for comment. Anyone with information relevant to the case is encouraged to contact the Mecklenburg County Sheriff's Office.
