According to reports, the Oregon shooter posted his plans to 4chan last night.
According to the source close to the investigation, authorities are looking at social media posts between a person they believe may have been the shooter, and others.
The conversation happened Wednesday night on 4chan.
In it, the writer talks about planning to carry out a shooting. Others egg him on, giving him suggestions on how to do it, and the type of weapons to use.
The responses are mixed -- with some users characterizing the would-be gunman as a pathetic loser. Others called him a twisted hero.
In the posts, there is a reference to the UC Santa Barbara shooter, who wrote a manifesto and videoed himself before opening fire a year ago.
"This is the only time I'll ever be in the news. I'm so insignificant," reads an apparent post by the would-be Oregon gunman.
