He had a well-documented history of both depression and addiction. For anyone reading this, Eeyore is oh-so-subtly implying that he was killed by Hillary Clinton, which is a conspiracy theory I saw going around on Facebook the day he died. According to right-wing conspiracy theorists, Hillar also had Kate Spade killed. I don't know if that's his other "secret hero," but that's the two people they're associating in this. I don't know where people come up with this stuff, but I'm pretty sure that's what he's implying when he's not sure he "buying the narrative" and "not sure about the facts."
People with families and kids and careers kill themselves all the time. Just because it's sad doesn't mean it's Hillary Clinton's fault.
