The reason I have a hard time accepting that it was accident are as follows.
1) How many people call 911, and state 'someone is trying to kill me' and and die accidently hours later?
2) How many people are last seen running down a roadway, disappear, and their body is only found after months of searching?
3) How often do police not check security tapes when a crime occurs in a gated community? How often are those tapes erased?
4) How often do the police state a likely explanation for death, (wandered into swamp and died of natural causes) before the body is found?
5) How often do the police continue to withhold the 911 call, even though there have been leaks and release of other information such as lie detector results? Police even sent letters to the media.
6) The missing hyoid bone, why is this the only bone missing, which would prove no strangulation took place if it was present and intact?
7) The deceased had a driver/bodyguard with her, besides not protecting her, he left before the police arrived.
Any number of these individual points by themselves are believable and plausible and are explainable in the accident scenario.
However all these facts combined together, stretches the laws of probability regarding coincidences. Now add in the discovery of other bodies, the characters CPH, JB and MP. Then sprinkle in questionable law enforcement behavior and I find it hard to accept SG died naturally.
Let me challenge you if you still disagree. Can you name another case where so many (7) similar coincidences occurred and the cause of death was natural causes?
IMO
