I can't seem to find a solid statistical study on the lottery-winner murder rate. "That Reddit post" says it's 20X higher than within the general population, and elsewhere I've read that it's more than 30X. I know, [citation needed] and I mean that literally - anyone know of a study?

Of course plenty of anecdata is out there. A glance at any of these stories ought to be scary enough to at least give you pause:

You can also search for "Tiffani Hill" for an example from just 3 weeks ago.

It's not ALL bad news of course:
