Can you show me a proof that LE said that?
LE only said that they are in touch with the last person she was in contact with. That doesn't mean it is AA
From MSM articles, it stated that when LE asked whether AA knew ML, he replied he never even have seen her. But LE found out her online profile pictures on AA's phone.
LE have never released info that AA was last to text her.
Please, don't combine facts with your opinions. That is the most annoying thing in these forums. (your opinions might be true but LE has not released information supporting it YET)
