Knee brace destroyed by staff blamed on prisoner

I am writing in regards to retaliation from officers for an attempted sexual assault by an officer that reached into my cell and tried to hit me in the private area. The cameras show this officer assaulting me. About 4 or 5 days go by and Sgt De Chow comes to my door and rolls it and tells us to strip out. During that process I hand my knee brace to him and he tries to bend it and it don't bend so he closes the door and takes my brace to the front of the run by the picket and takes it apart. A Lt. Simmons shows up and takes my brace and leaves the block and Sgt. DeChow comes back and puts me and my celly in the dayroom. I ask the Sgt why he took it apart and he stated it doesn't matter it's contraband, the metal inside could be used as a weapon.

The knee brace was given to me by UTMB hospital Galveston because I have a messed up left knee and need it. I'm placed in lock-up by Lt. Simmons and when I ask why he says investigation from someone higher than him. Three days go by and Sgt. Easley investigates a case for 13.0 destruction of property saying I tore the knee brace up. Note all of this is on camera where I was housed and a review of the cameras will show the Sgt. DeChow taking my brace to the front of the run pulling it apart. I feel like all this is being made up in retaliation for the grievance I filed on an officer prior to this.
