I didn't watch the video, I clicked through the little chapters at the bottom, I was just looking at causes of death, not even the names or pictures.
A lot of suicide, sometimes method is mentioned. I think the vast majority were suicide or overdose. One said "accidental overdose" but most did not.
One was pushed out of 1st floor window, and one was murdered by a hammer. There was at least 1 car accident and I saw pancreatic cancer.
I kind of clicked quickly but OD's and suicides were prevalent for sure, I didn't see every death, but most of them.
