The guardian must have changed the headline at some point. The link itself still says "serious injury," but when you read the headline:

Man dies after jumping into tiger enclosure at Yorkshire zoo

Yeah, the initial save on archive.org still has the injury headline. I always get confused when I don't see a little blurb at the bottom saying it was edited from the original with new information. Maybe I missed it.

Anyway, fucked up that happened. I wonder if it was a suicide or if he dropped something in there, or what? The "jump" makes it seem self inflicted, either way. The tiger didn't pull him in, so I hope they let it be.

What a way to go
