About two hours later, the writer posted a second message: “I've had my fun and now I must leave. ...
“I never said anything about a school or killing people, you all let your imaginations and assumptions run wild, and it fed your own morbid fascination with violence sprees. I live about 18 hours away from Wyoming, ... Have a nice day, thanks for filling my past 2+ hours with all kinds of lulz, hue hues, chuckles, and giggles.”
Authorities determined the Internet Protocol address originated from AT&T in Oklahoma City and traced it to AT&T customer Glenn Kirkham, according to the affidavit.
An FBI background check showed Kirkham possesses an Oklahoma license to carry a concealed firearm.
FBI agents went to Kirkham's apartment at 2705 W Interstate 240 Service Road about 2:50 p.m. Monday. When asked if he knew why the FBI was at his apartment, he said it was due to the posting he made earlier in the day on the Internet bulletin board 4chan, according to the affidavit.
Kirkham told agents he “posted a vague falsehood” and “posted a work of artistic falsehood,” according to the affidavit.
He told agents all the 4chan posts are works of artistic falsehoods and anyone would be a fool to believe any posting, according to the affidavit.
