They are 2 unrelated items.
1 - it was only reported if her leaving work, we don’t know how many people witnessed her actually leaving and it seems there is no video evidence. So was it a staff, multiple staff, resident - who actually witnessed
2 - is it possible it was assumed she “left” but wasn’t actually observed leaving in which case, is she still in the building somewhere. Did a resident assault her and it is unknown, or covered up, or a staff involved
Imo I hope they have solid evidence to say she left
The new search info may indicate they have some kind of evidence of her leaving
