I can’t imagine her mental state, that is of course, if she is still alive.
Both of her parents are dead at the hands of this perpetrator (assuming he is a lone one), and she would likely be despondent.
I do have a feeling that a break is forthcoming. It’s hard to commit a crime like this and leave absolutely no trail.
With the passage of time, data can be analyzed, forensics can be analyzed, and surveillance footage can be watched.
We’re in the dark right now, but (hopefully) we’ll have some information soon.
