The recent school shooting in Red Lake, MN were committed by a teenager named Jeff Weise. The AP reports that Weise had been active in some neo-Nazi chat rooms and message boards.

Weise may have posted messages on a neo-Nazi Web site expressing admiration for Adolf Hitler, going by the nickname "Todesengel," which is German for Angel of Death. In the first posting under that name, the writer identified himself as Jeff Weise of the Red Lake Reservation

While the original message board pages have now been taken down, Wes Roth has a link to the Google cache of one of those pages.

Hmn, after a recent discussion with some misinformed people I had to ask you guys, why are people so close minded?

By the way, I'm being blamed for a threat on the school I attend because someone said they were going to shoot up the school on 4/20, Hitlers birthday, and just because I claim being a National Socialist, guess whom they've pinned?

Chilling stuff.
