Rest in Peace Capcom Vice-President Mark Beaumont.
Hey sliem, here goes my downvote to you. There are numerous conditions that can determine a sudden death. Maybe you haven't noticed, but CEO, COO, and much of this executive positions carry a very busy life ( as you can see, a lot of them may have luxury houses, pool, whatever, but the wrong concept of these persons enjoying all their stuff is just wrong) Most of this guys are damn hard workers and don't even take their time to evaluate their health. When something goes Boom, it's already too late for them. Busy lives take quite a toll from them. This is one example and a prove point to show you how several conditions can make you meet death.
Not everything is homicide. ( and of course it could be one case) ..but that's what investigations are for.
