Deaths in South Carolina, Negligence by Prison Staff

I want to report an incident that occurred here at Perry Correctional Institution in South Carolina. On 24 July 2015 I witnessed the officers let an older white male die from falling on his floor face first, and the bone in his nose was forced to his brain. He was left on his floor from 1pm til 4pm, before they realized that he was dead. After they realized he was dead they left him on the concrete floor until 10:30 or 11pm that same night. All the prisoners, including myself, who were locked behind the doors on SMU at the moment continued to tell the agents what had happened hoping to get some help from the outside.

Then another white male told the officers he was going to commit suicide, but (building upon truth) the officers ignored his life threatening comments, like they didn't even care. He jumped off his sink twice before he was dead, but after the 1st jump he was bleeding excessively and the officers, lieutenants, and captain continued to spray him with the MK-9 can of gas, which they say is supposed to tame him. My question is, why spray with gas when he is threatening his life? Why didn't y'all do y'all's job and run in the room and save him from killing himself instead of just sitting there watching him drain the life out of his body.
