The gun that was shown in the other video is on the other side of the fence, about 10 feet to the kid's right.
By the way, that looked like a heart shot, the kid was dead within seconds.
there is a pic where there is a gun on his right hand. but i believe it was dropped way before the office shout “drop it” and shoot.

Which officer’s cam shows the discarded firearm?
