About the broken jaw, (ok the story could be fake), I broke my ankle, as well as sprained it.
I walked into ambulatory ER, told them what happened and they said, “well you are walking on it so its not broken”.
Told me to come back the next day, if I was still bothered.
I did, that doctor begrudgingly took an xray, my ankle was broken it two spots.
So it’s possible that his jaw was broken and the docs missed it, also several of the articles said he had surgery.
I found this Zachary Tennen interview which confirms my belief that this kid wants only to make the other guy pay, despite the truth otherwise.
