The documentary piece may be fake. Avicii was supposedly killed because his girl friend (some Danish royal I believe) had shown him documents from her deceased father that showed child rape and murder.

Cornell and Bennington were supposedly involved together for some expose.

Bourdain was supposed to have been present at Chateau Marmont when Adam Schiff killed a child by overdosing him to rape him.

The list of those murdered to cover their crimes against children is much longer than just these four names.
