I don’t think they even got the right person on the video. He (or she?) was just pointing with the finger and saying “pew pew pew”. Just a coincidence that the CEO had a heart attack at that moment.

Doesn’t look like anything to me

It was a heart attack. I think he got denied the medicine he needed. It happenes more often than it should

I didn’t see anything

It’s likely just the power of suggestion combined with confirmation bias : you see a dude with a jacket and a hood on surveillance camera footage, given the context you assume it’s the same guy. But looking at it more closely, they differ in many ways. That theory doesn’t have a leg to stand on

No, it’s not him. Different nose and different jacket.

Why are the skeletons all having a seizure?

I heard it was before. Probably just a look of peace and content because he knows his path is true.
