Glenn Arthur Cox, 52, was held at the Idaho State Correctional Institution south of Boise when he died in his cell in the early hours of September 22, 2017. The Idaho Department of Correction said he had been assaulted and was found on the floor of his cell, and he was pronounced dead at 1:45 a.m. The Ada County coroner said he died of injuries related to an assault, and the Ada County Sheriff's Office is investigating; his cellmate was named as the only suspect, though no charges had been filed as of the reports. Family and friends said he had long struggled with alcoholism, had recently been diagnosed with a mental illness, and hoped treatment would help him stay sober. One staffer was reported to have worried that a head injury he had days earlier was an assault, but according to the reports it was never formally documented.
