I’m wondering if this is some sort of preventative privacy measure, as during cases like this, and in this day and age of SM, if her name is released people might sleuth her, (cough). And perhaps since LE has cleared her of any involvement, if there is something in her criminal background, this may not need to be revealed publicly as it is unrelated.
As one who is a private person and doesn’t do SM, I can understand this desire for privacy, especially during a time like this. If she’s been cleared, then why would everyone need to know her name? It would serve little purpose, imo.
