The brown jacket incident was on another video. The cops hit her ( yes look closely, earlier in the video. It was a woman.) That was the same live stream where the guy had a heartattack.
Here is one of the videos that very briefly shows both persons being trampled.

Brown jacket could be male or female. Cops swarm in and hide both bodies.
I am also very curious where brown jacket is now.
