That is right.....just because Jonah said he was at the gym does not prove that he was actually there. I find it odd that no one else has corroberated his "story"...........and there has been no proof that the teens actually flew out in the early am.
According to statements taken from RZ and XZ by LE, the only two people present at the time of Max's injuries were the two of them. Demanding proof of where JS and his other children were at the time is no different that the doctors questioning their statements about how Max was injured.
