The Arapahoe County Sheriff’s Office is conducting an investigation after an inmate in a booking cell at the Arapahoe County Sheriff’s Office Detention Facility was found deceased when deputies were conducting an inmate count at 5:25 a.m. on Thursday, Oct. 22, 2015.

During the inmate count, deputies approached a holding cell housing two inmates. One inmate responded to the deputies, but the other did not. Deputies entered the cell to check the welfare of the inmate and he was unresponsive. Deputies immediately notified medical staff and began lifesaving efforts, but those efforts were not successful. The inmate was pronounced deceased at 5:44 a.m.

The inmate, 28-year-old James Proctor, had been arrested without incident by the Littleton Police Department on a warrant for failing to appear in court on a DUI case and brought to the Arapahoe County Sheriff’s Office Detention Facility at approximately 2 p.m. on Wednesday, Oct. 21. He was awaiting assignment to a housing unit. Deputies had been in the cell at 2 a.m. on Oct. 22 and do know that the inmate was alive at that time. The investigation is on-going, but there is no indication of foul play.
