It was posted in /r/news but didn't make it to the front page. Weird indeed.

The news got removed from multiple subreddits. Even a picture of him was on the frontpage and on top of /r/pics/ for a short time is now removed.

This is a good thing.

I guess Reddit is trying to avoid the Werther Effect (copycat suicides) and a huge Reddit Mob attacking random bystanders.
