Let's look at the facts:
- Shannan freaks out about something and makes the rational decision to call 911. We don't know what the call contained thus anything she said or the way she acted is just speculation. Anything we've heard has been through witnesses who may or may not have embellished or altered due to their own biases or want of saving their own skin. We at this point just don't know. Said witnesses also claim she was doing drugs - most likely but again we don't know for certain.
- Shannan is bi-polar. Being bi-polar does not make one hear voices or hallucinate or think that people are after you.
- Shannan is known to do drugs. It is possible that drugs did this though I personally can't vouch for that. Her behavior, IMO, seems a bit extreme for bad-trip behavior.
- Shannan answer's Pak's question "Have you seen Fear & Loathing in Las Vegas?" in a way that convinces him she is acting and she is rational. However this is witness testimony so we don't know about this for certain and technically isn't fact but I fail to see why he would make this up when all of the witnesses are claiming she was drugged up and acting irrationally.
- A call is made to a pharmacy, most likely a rational decision to make by whoever made the call. Speculation is that it is drug related but again, that's speculation.
- We know Shannan flees and ends up at GC's house. It is debatable on whether or not he opened the door as he has stated that he has done both. A local heard from his own mouth recently that he DID NOT open the door and let her in. This was also in a news article very early on. If I were him, I wouldn't open it (sorry). If he opened the door and allowed her in, she was acting very irrationally. However if he did not let her in then her behavior is rational. If he let her in, it's irrational that she ran off when he said he was going to call the cops and hid behind a boat, but it isn't if he refused to let her in and used the "I'm calling the cops" as more of a threat than an offer of help.
- Shannan disappears into the night and ends up in bramble, her belongings the length of 4 football fields away from where LE eventually found her. This is irrational, unless some items are found scattered throughout the swampy area and not just one general area.
- Dr. H calls some people that Shannan knew. We don't know why or how he got the numbers. According to Sherre, a witness that I am inclined to trust more than those that Shannan was with that night, he claimed to have treated Shannan and had her with him. This is such a bizarre claim that I personally am inclined to believe it. Dr. H says he called because the family asked that he do so. We don't know why they would have asked this at this point and most agree that this is irrational and that his behavior and letters are borderline irrational and defensive.
- The SK called his victims' loved ones.
- After Shannan disappeared, the SKs last known victims did not bring their cell phones with them before they disappeared, odd behavior for them.
Different drug cocktails have different effects on different people. Statistically, the symptoms can be described as a Gauss bell graph for any specific mix. So, since we can't estimate, what the cocktail was, nor whether it contained substances, she wasn't used to because they were not in their normal supply (and most likely, we talk JB's stash here, not SG's), there is some chance of unforeseen reactions.
Now, drugs are abused BECAUSE they take the mind out of reality. So any further idea, any drug abuser is after taking the drug 100% rational is off the track BECAUSE they take those stuff especially with the purpose to flee reality and by that rationality.
So, she made a 911-call of 18 minutes. And still there is some time before she was seen by GC fleeing. First thing, what makes you think, it was rational and not symptom of a beginning drug induced paranoia? She didn't sound rational enough to the police to send someone out immediately. And if her 911 was rational, the decision to stay there till the pharmacy is called contradicts that. Because either the 911 call was rational, then she would have been on the run afterwards because she would have really had rational reasons to assume, someone was going to kill her. But obviously, she had not enough reason to run immediately. So we can, by purely looking at what she did and didn't conclude, she was already irrational in her behavior when the 911 call happened.
She was bipolar. Fine, that has nothing to do with hallucinations and delusional behavior per se. But the effects of drug related paranoia and other strong feelings can be amplified in patients with bipolar disorders. This means, SG was especially prone to suffer from such strong irrational emotional effects of drug cocktails, she wasn't used to (which is by the way mentioned also on the package insert of a long list of psychoactive prescription substances)
It is nice, Pak was convinced of something. But aside of all bias and intentions and the possibility he lied when stating that part, on what exactly did he base that judgment? That she remembered something from a show, she had once seen in Vegas? Or didn't remember it? Why is that in anyway considered a test with any form of legit result in the first place?
GC probably didn't offer to let her in or opened the door wide enough to let her slip in. Most people wouldn't if in the middle of the night someone is at the door and starts to tell about people who would be after her. Especially not, if the person at the door makes a rather out-of-control impression. So forget Coletti as far as the door story goes. Important is, he saw Pak and the SUV and he sticks to that part of the story.
SG disappears and is found a year later with her belongings spread out in the vicinity. One earring however was found earlier, if I remember right, not too far from CPH's house, not JB's house. So, she fled, she got lost, she died in the reeds. There are two details interesting:
a.) She fled direction water, Pak was minutes behind her. That means, she had no split second decision to make and no other choice. For a person, afraid of water fleeing in the direction of water indicates at least a disoriented state of mind.
b.) She didn't spread her belonging around herself or they would be all over her escape route and for sure, she wouldn't have taken the time to get out of her jeans while on the run. And we can -obviously- also dismiss any idea, she spread her stuff out post-mortem. That leaves us with the knowledge, someone else did it. We don't know how she died, but we know, someone saw the need to cover it up and this someone was neither controlled nor smart enough to drop the purse with the ID at least somewhere else to make identification harder. So whatever he was, he was for sure no experienced SK.
