The story we have been told has a group of young adults going into the woods to smoke weed together. And then her murdering someone in a violent manner (stabbing over and over)… which very well could have been planned. Modern studies are starting to show that marijuana is tied to people having psychotic breaks in people with bipolar disorders. Which she was diagnosed as bipolar… So it could be completely unrelated… but this situation would be even more horrible if someday we find out she did infact have a psychotic break and none of it had been planned.
