A split second before the crack of the gunshot, a distinct ball of faint light can be seen darting through the tree in front of the Sorensen Center. If it is indeed the muzzle flash, then that puts the kill shot being fired from the roof of the Sorensen Center. Such a trajectory better matches the analysis of Charlie Kirk’s wound arrived at independently by both @chrismartenson & Baron Coleman (YouTube, H/T: Baron’s eagle eyes).
At the end of the video, I’ve included a rough layout analysis of the locations & trajectories. In the next tweet below, I’ll link the source video.
