Suicide rate is 2.5 times more likely than murder. There’s currently no reason to not believe them.

I say this because if there wasn’t footage of him buying it, not mentioning it would be the obvious way to go if you were trying to cover up possible foul play. Saying there is footage though; footage that never gets produced screams the opposite.

So if the footage didn’t exist, they never would have even hinted that it does.
