I agree. The reasoning behind her leaving with strangers, is of no consequence. Expectations of safety differ from one person to next. At this point there is little to go on.
The history of drug abuse, may help point PD in the right direction, if in fact that was the case. People in those circles, tend to know each other. The time lapse from 22:45-00:14, is a roadblock. Even if PD has identified, the persons she left with, they could have or there story could easily be, that she was dropped somewhere, and the text may refer to whole other strangers of which we have not video. If there was anything nefarious going on with the strangers she left with, we can all be that the story will not e the truth, and will be of little help in locating her.
