Personally, I think that everyone wants this to go away. Especially her parents. There is a fine line in these types of cases. Too much zealous police work on the obvious hoax, continues to take time away from actual crimes.
And her parents were not part of this hoax, as far as we know, so why should her mother be investigated for the actions of her daughter?
I think she should take a long break somewhere, not unlike Holly Courtier, who was "lost" at Zions National Park. Holly's family hustled her to "mental health treatment" fast.
The problem here, is that Carlee still appeared to be tone deaf about her actions, and consequences of her behavior on others. She continues to move forward. At least she hasn't taken a card from Jussie Smollett, who has continued to double down that he is innocent.
