The conspiracy theories here are fascinating and chilling, in a very Creepypasta way, but judging from those posts from people who claim to have known her and her behavior, you can tell that she is just a bit fried from drugs. I have a very good friend who is now not very well (she developed schizophrenia over the past couple of years) because of an excessive use of acid and ecstasy while she was dating a drug dealer. She speaks in very disjointed ways and jarringly changes expressions and moods. It's a bit unsettling, but it is very characteristic of someone who has essentially fried their brain on drugs to an almost irreparable state of "normalcy".
The amount of attention this conspiracy is getting though is something else. The Internet, man...
