What Happened to the Assisting Officer?

Preston Hemphill, who is the white officer. was finally fired on February 2nd, and he's the one that can be heard if you all watch the video. He also took a photo of Tyree Nichols after they beat his ass and texted it to six different people. There's no real information yet about what's going on with her. The other part about the test messages, especially to the female person, that would explain some things because I still don't understand why to beat that man like that.
