When BB saw Shannan, she had no jacket, and purse (as I recall). She had her cell phone in her hand, though. Her jacket and purse would have been in Brewer's house, likely, once she arrived that evening at his house. Would she have had on her jacket and purse when being told to leave the house? Unknown. Jacket supposedly wound up near Brewer's house/driveway, along with one of Shannan's earrings(?) I don't think she lost those due to her own actions. Perhaps she lost her purse somehow between Brewer's house and BB's house, unless BB definitely saw her with her purse, and Shannan would have been wearing her jeans.
Back to the affidavits. Page 10, JS Sr.'s affidavit doesn't mention any talk from TC that Shannan's driver was there at the same time as TC and CPH were there, after Shannan was at BB's house. It would have been easy for TC to throw MP's name in there to make him responsible, and deflect, but he did not tell JS Sr. that her driver was there, or another unknown male. They would have no reason to protect MP.
IMO, with what we have right now, I (my feelings, only) don't think Pak murdered Shannan. I think CPH medically contributed to her demise, and failed to call 911 for proper assistance. IMO Shannan was placed where she was when she was almost deceased and unresponsive, or deceased. By CPH, or CPH and Cannings potentially helping. Or, after treatment from CPH in presence of TC, at the very least, she ran and hid in the reeds, and died due to a medical reason which could have been in part caused by CPH. Those are just my own thoughts, at the moment, given what we have.
I've re-read the affidavit of Joseph Scalise, Sr., and I'm not sure if what he says is considered hearsay, but Joseph Scalise states that Thomas Canning, when talking about the morning of May 1, 2010, said that "Shannan was agitated and out of control", and that "he and Hackett tried to calm her down", and that " Hackett gave her a sedative to sedate her."
Joseph Scalise was not a direct witness to the events on that morning. In his affidavit he states only what he heard from Thomas Canning, who claims to be a direct witness to the events. The fact that Thomas Canning does not mention Michael Pak in this conversation with Joseph Scalise does not necessarily mean that Michael Pak was not there.
I lean toward believing what Mari Gilbert told Detective Camacho and what she eventually stated in her transcript, which was that Peter Hackett told her that he treated Shannan and she then left with her boyfriend. She had no reason to lie to Detective Camacho at that point, and as a concerned mother would have tried to give the facts exactly as she knew them.
We know that Shannan was suspicious of Michael Pak, and that she made some serious accusations toward him during the course of her 911 call. He had Shannan in a very vulnerable position when they were at Joseph Brewer's house. If she were ultimately treated with a sedative by Peter Hackett and then left with Michael Pak, he would have her in an even more vulnerable position. If Shannan were to survive this situation what repercussions would be waiting for him after the events of that evening? He must have had to weigh his options.
What were his options at the point when a sedated and unresponsive Shannan left Peter Hackett's house with him?
He could've taken her home, or to the hospital, or contacted the police. These options would all leave him with a lot of explaining to do and most likely a very serious legal problem, after all, he was involved in criminal activities such as sex trafficking, drugs, prostitution, etc.. What did Shannan know that made her accuse him of conspiring to kill her? How would a serious legal problem or Shannan's knowledge of a plot affect his relationship with either his current or former employer Joseph Ruis?
Leaving Shannan in the marsh at Oak Beach, and then leaving her belongings in the vicinity of Peter Hackett's yard would allow him to avoid answering to Alex Diaz, Shannan's family, the hospital or the police about what happened to the unresponsive girl he was with, and he could avoid any serious legal problems that might arise and possibly put him in danger from Joseph Ruis. Everything Shannan knew about him would die with her, and any investigation resulting from the three 911 calls made to the SCPD that morning would lead to Peter Hackett.
