I'll grant you that. The entire scenario is "Pak said". But that is all we have to go on, from that perspective. On the other hand we have accounts of "voices in the background trying to calm her down" (according to the "reports" about the receiving end of SG's 911 call). It is all we have to work with.
IMG, I see Brewer then kicking her jacket out the front door, (IIRC, he said it sat in his driveway for days) closing the door, and washing his hands of the whole affair. Nice guys, huh?
Which would put the jacket at Brewer's driveway, not at somewhere on Anchor Way ...
However, what I would like to do is, to hold every part of Pak's statement against what is possible and reasonable before I buy the thing in whole.
- I buy the drug part because it's consistent with what GC says, the impression, she left with the dispatcher and her erratic ways through OB
- I buy, that JB called MP in to get SG out of there, because it would be a logical reaction, not because JB was annoyed. My guess, IMO, I am thinking, JB may recognized the signs of a bad drug reaction as did MP. That would give JB motive to get SG out of the house as fast as possible before she may ends up as oded body behind his couch. On the other hand, MP may would have hoped to calm her down because it's no joy to drive with a paranoid screaming girl in the car praying, she doesn't collapse and ends up as body in the car.
- what I don't buy is the part, where MP just sits down and waits for her to finish her 911 call. To come in contact with police was the last thing Pak wanted. Well, or the second last thing. The last would be to come in contact with the police while in company of a drugged prostitute he drove to a customer who now would have motive to wash himself clean.
So, seeing it from Pak's point of view, he had two options. Either try to talk her back to reality or just threaten to leave without her and hope, it would make her run after him because he was her ride home. So my guess is, he went out again pretty soon, he didn't sit on that couch for long. But you're right, one of those voices on the tape could be Pak's. Which gives us JB's voice and maybe Pak's voice, but still not "several".
- the point, I can't figure is, did MP know and believe, SG called 911. If he knew and actually believed it, it would have been for him the crossing of the next threshold. And given, there were at least two fully grown males (Brewer and Pak) there, it wouldn't been a thing of impossibility to grab her and just carry her to the car. But since the tape ended (according to John Ray, who read the transcript but didn't hear actually the tape) with SG running out (and JR in 48 Hours says nothing about her stumbling), we know, that obviously didn't happen. Why not?
See, if MP knew she called 911, to do nothing is somewhat contradictory behavior on MP's side. It makes only sense if he didn't know.
