Especially when screaming girl, who calls 911, stating someone is trying to kill her, being followed by a guy, is found dead behind one of the houses of a door she knocked on, then retired LE says she wasn't upset in the 911 call, she was calm. But she still ends up dead. Go figure.....
Who said she was screaming?
That, I think is an extrapolation here based on her 911 call being called irrational. No one said she was screaming. She was on the phone for over 20 minutes, her life was not in danger. If it was, she would not have been on the phone for that long. If she had been on the phone screaming that someone was trying to kill her, LE would have arrived in force long before the phone call was up.
Then she runs to a neighbor, who offers to help, but she runs away again for no apparent reason. Once more, irrational paranoid behaviour.
She didn't die behind his house either.
She wasn't being "followed by a guy", the person who was her driver/security was doing what he was supposed to be doing and looking for her. He left after he couldn't find her. What was he supposed to do? He didn't know where she was, she was doing something that was likely illegal, police were going to show up (with explanations being required), and he was just an employee, not family or a friend. Of course he left. So would you. But he did come back later with the boyfriend trying to find her when she failed to show up at home.
The LE who commented on hearing the tape says she was "calm" (or whatever). He didn't say she was rational. So, nothing odd there, except that it it didn't agree with our extrapolation of the description "irrational". Ya, so, there must be something wrong because we assumed that irrational meant screaming. Well, maybe it didn't. Maybe it meant she was being incomprehensible and rambling. We didn't hear these tapes but this LE person apparently did. So it was probably the latter.
If someone is experiencing a paranoid delusional episode, perhaps high or in the process of ODing or whatever, and runs into a swamp in the dark, winding up dead is not an unreasonable outcome.
