While responding to the assault, staff reported that another inmate may have been killed in a separate part of the institution. The officer who was allegedly attacked was expected to survive. The officer who was attacked did survive and in January of 2021 was attacked by a different inmate suffering several stab wounds again. He also survived this incident.
