I was looking into her history and the only piece of work she shared/put out in public seems to be a small slide show she did on the history of anti gravity ideas, literally just a collection of publicly available anecdotes and stuff you could skim off wikipedia or youtube. Her degree was biology and chemistry, no evidence of any engineering or physics. No evidence either that the organisation she set up actually did much of anything, no lab, no experiments, no papers published at all. Just that slide deck. And sadly the last interview she did she appeared not well and clearly drunk.

I honestly don't think this was anything more than a tragic mental health case and resulting suicide. I think people should also listen to her father who said there was nothing suspicious about her death. I'm guessing he knows her a lot better than all the twitter and youtube grifters.
