I'd really like to know:

4. Why were they scared off by Jussie? Remember, Jussie told Robin Roberts, "I didn't run. They did." Did Jussie have a gun?
Someone making up this story out of whole cloth, could think it was plausible that someone would believe their attackers running away with no provocation, merely because they wanted it to be so and because they were the creator of the entire narrative; thus no blocks to the imagination.
Contrarily, if I were LE and this were the story I'd heard from the alleged victim of the crime, I'd be looking for eyewitnesses surrounding the scuffle to corroborate this contention.
Which it seems LE already did, and came up empty, since except for the massively questionable "white redneck" spotting, nobody saw anything.
Because if JS didn't have a gun or similar, the primary thing that would randomly make strong attackers mid-attack "run" away, would be fear of discovery mid-crime. I.e., either (1) a person or persons walking towards them; or (2), someone or something making enough sound to make the attackers fear that they might be set upon (the cliche'd cat knocking over the metal lid of a trashcan, etc.).
I also question whether or not people in the middle of a knock-down, drag-out fight, would be compos mentis enough to hear anything other than the heavy breaths and grunts of their own and their victim's; so one would think the combatants couldn't logically hear mere footsteps approaching them, and would instead have to be alerted by things like said pedestrian yelling "Hey! Break it up!" or similar. In which case police would then also likely have an eyewitness. Which they don't yet have.
