There’s no proof of a connection to the mass shooting at Umpqua Community College, but plenty of people are talking today about a post on Internet bulletin board 4chan from last night that warned fellow posters not to go to school tomorrow “if you are in the northwest.”

The 4chan community is notorious for tasteless pranks, sometimes involving threats of violence from anonymous posters, so anything 4chan-related should be taken with a large grain of salt. However, this particular post, captured in screen shots, seemed eerily prescient.

The post reads:

Some of you guys are alright. Don’t go to school tomorrow if you are in the northwest.

happening thread will be posted tomorrow morning

Follow-ups to the post egged on the original poster (OP), with some giving advice and suggestions.

“I suggest you enter a classroom and tell people that you will take them as hostages. Make everyone get in one corner and then open fire,” reads one reply. “Make sure that there is no way that someone can disarm you as it it possible. I suggest you carry a knife on your belt as last resort if someone is holding your gun.”

Others on the thread has less supportive messages for the original poster. One wrote, “Hey OP. Please stop being a faggot. I’m asking you nicely. Also, if you are going to do something please don’t use any guns. It makes it harder for us gun owners who aren’t complete fucking faggots.”

Again, none of this is proved to be connected, but it is drawing a lot of attention, especially from those familiar with the previous exploits of 4chan regulars.

Again, no connection between today’s shooting and last night’s 4chan post has been confirmed, but the posts on 4chan have confirmed for many just how low posters on the site can go.
