The gunman who went on a shooting rampage at a west Oregon college targeted all females in a single classroom, according to police reports.

Chris Harper Mercer, 26, walked into a classroom at Umpqua Community College and forced his victims to line up before opening fire on them. There are 10 confirmed fatalities and 7 injured. All of the victims were females ranging in age from 18 to 34.

According to published reports, the mixed race gunman asked his victims to state their religion.

According to CBS News, Mercer was a gun enthusiast and NRA supporter who mentioned Virginia news crew shooter Vester Flanagan in a social media post.

Mercer apparently posted his murderous intentions on a 4chan woman hating channel on Wednesday. Many of the users encouraged him and urged him to “do it”.

After news broke of the college shooting, 4chan posters celebrated and boasted of posting “in epic thread.”

One anonymous user mocked news reporters who flocked to the channel, writing “hi journalists.”

The 4chan room Mercer posted in is described as a “safe haven” for social outcasts and misfits who don’t like women. They used the term “beta” and called themselves space robots because they are unfeeling and lack empathy for others.

The thread has since been removed and the feds are investigating.
