What percentage of suicides go out into unfamiliar woods and then kill themselves in such a way that their body won't be found for over a year? And also how many do it right after packing their bags getting ready to go on a trip? Plus there is the lack of a suicide note or anything else that might indicate why she would commit suicide. ... I can't imagine she would be so callous towards her parents and friends as to put them through the agony of not knowing what really happened to her. I don't have specific research for you but many people go out in the woods to kills themselves, it's a popular place. That she wasn’t found quickly, just a few miles from her apartment, is not her fault but the fault of an incompetent police search. Many people, possibly most, do not leave suicide notes, for example Vince Foster. This happens in cases where the person wants to disappear and does not want to or can not rationalize their decision. One of the side motivations for suicide is to punish people, so being callous towards friends and family is hardly a deterrent in the mind of a suicidal person. Or she may not have left suicide clues because she did not want to hurt her family, wanted to leave them the benefit of the doubt. Unless Chandra was a drug user and tried to leave without paying off her drug dealer, or had someone else very angry at her, the odds appear to me to be very low that she was murdered.
Do an advanced google search on the phrase "no suicide note" and you'll find lots of similar cases to this.
Even disregarding the new bits of evidence (fractured skull or that she may have been tied up) i still think she was always an unlikely candidate for suicide. My point though was that when you take all the unusual circumstances surrounding her death, and not simply explain each of them away one at a time, but take them all in total then they dramatically shift the odds in favor of homicide. And from what i've seen and learned of Chandra since the time of her death she never struck me as the suicidal type but rather just the opposite, as a fighter and someone who would quickly rebound from life's disappointments rather than just giving up. And finally i simply can't believe that going to a park that you have never been to before and then going to a remote location at that park to kill yourself has ever been a common way for people to go about ending their lives.
