Suspect’s blog showed malicious thoughts

"I have decided to give up on trying to convince people that I am a real person, with honest and good intentions, not some evil monster they should be afraid of," he wrote last year.

The entries include excerpts from a book he said he was writing based on his conviction at age 16 in Tacoma, Wash., of sexually assaulting a 14-year-old boy at gunpoint. He documents his nightmares, his anger over serving 20 days past his 20-year prison sentence, his difficulty making friends and dating, and diatribes against police checking on his whereabouts and confiscating his computer and digital camera to check for child pornography images.

"Of course I am clean, they might find some pictures of me naked, non-sexual mode photos I used once to make a birthday card for a girlfriend once, but that's about it," he wrote in an entry last August titled "Home Invasion."

Angered over sex offender stigma
His irritation with registering as a convicted sex offender and having that information publicized on a Web site maintained by the police department in his home of Fargo, N.D., was a frequent topic. He submitted anonymous questions about law enforcement's efforts to monitor sex offenders to Fargo Police Chief Chris Magnus periodically through The Forum newspaper's online "Chat with the Chief" feature and then posted the responses to his blog.

"I think it's pretty amazing you believe that as a registered sex offender your situation is comparable to being a Jew or member of another minority group persecuted by the Nazis," the police chief wrote in a May 2004 reply to Duncan's comparison of the Fargo police policy to visit the homes of high-risk sex offenders to the 1935 Nuremberg Laws that stripped Jewish people of their German citizenship.

Magnus said this week his officers first learned of Duncan's blog when they questioned friends and neighbors after he failed to check in with his probation officer in May.

"Whatever questions he submitted were submitted anonymously, and I certainly had no idea I was corresponding with him," Magnus said. "In retrospect now, it is a little creepy, especially after I went on his blog to read how he has this vendetta against anyone who he felt was responsible for his situation."
