YouTube videos from people who've met mass killers

I'll start with a few, feel free to post more if you find some.

Caleb Sharpe:

Also, there was an animated one I can't find anymore with a guy saying he was friends with TJ Lane. If any of you know which one it is, then I'd be happy if you would share it.

I don't know if this is what your looking for, but there is a video on YouTube from a woman who escaped the Garanhuns Cannibals, who killed 3 or more victims then turned their bodies into snacks (which they later sold) in Garanhuns, Brazil.

Those types of videos are interesting, but I'm personally looking for videos from people who knew killers before they committed their crimes. There was one thread about videos from school/mass shooting survivors, but in this thread I'd like to have videos of people talking about their experiences with killers before they were infamous, particularly mass murderers, since serial killer ones are a bit more common and easier to find.

I remember seeing a video from a classmate of Alec Kreider, around 6 months ago. Now I can’t find it, I’m guessing it was deleted.
Speaking of lost videos, Skater Landau (a not-too-close online friend of Randy Stair) made a few videos talking about the shooting, but were deleted shortly after.

Something close to what you’re saying would be from a fan of Mr. Anime, who talked to him through internet. It’s pretty much his live reaction to hearing about the killings.
