It is well known that Barry was a genius, literally a rocket scientist before he got into pharmaceuticals. Before his death, I read on the internet, sorry I cannot remember where, that he was working on a synthetic version of Cannabis. I assume that could be patentable, with epic financial consequences. Whether or not this would have had anything to do with his death, and Honey's I do not know, but if anyone, or any company, or even any country planned to steal it, or wanted to eliminate the competition, it might have been a motive. Just speculating. IMO
