I'm sure not everything DM saw and recounted to LE is in that PCA. LE doesn't included everything, just enough to convince a judge of probably cause.
All I can think of DM's experience is she was, in her mind, prey and a predator was approaching. I real think it came down to her brain saying freeze, don't move, if you move, you die. It's just terrifying to think about. BK could well have seen her but not seen her, possibly because of his state of mind.
It sounds like, according to what we know from DM's accounting that we've been told, that she was woken around 4am to the noise from Kaylee and Maddie's murders. Shortly after noises from Xana's bedroom area. I think BK may have heard the Door Dash exchange activity and the in coming downstairs he saw Xana was up so went to that bedroom, maybe thinking, oh no did she hear me?
DM hears those murders and then the confrontation, her mind tells her, just don't move. It's so visceral.
Why doesn't her mind, after locking her door in probably choking fear and confusion, convince her to call 911? That is a question but I'm not going to judge because at her young age and not knowing her personality or history, it's impossible to know how her mind would cope in that situation.
That young woman is lucky and blessed to be alive. When BK is finally put on trial the public will know DM's full experience I'm sure. She'll mostly likely never let it go...ever </3
