The dude in the very first video, in the red Trump hat,said the kid was carrying the rifle as he climbed up the building right before the shooting.
That would probably be after he retrieved them from the trees then.
I don’t see how he could possibly bring it all the way from his vehicle.
I see no problem in the hidden tools theory.
I’m done speculating.
