Curtis said he's not sure exactly what led to the bad blood. It involves the men's time working together, a broken promise to help with a book by Curtis and an acrimonious exchange of emails, according to Curtis.
The two worked together at Curtis' brother's insurance office years ago, Curtis said. He said Dutschke told him he owned a newspaper and showed interest in publishing his book called "Missing Pieces," about what Curtis considers an underground market to sell body parts.
But Dutschke decided not to publish the material, Curtis alleged, and later began stalking Curtis on the Internet.
For his part, Dutschke said he didn't even know Curtis that well.
"He almost had my sympathy until I found out that he was trying to blame somebody else," Dutschke said Monday. "I've known he was disturbed for a long time. Last time we had any contact with each other was at some point in 2010 when I threatened to sue him for fraud for posting a Mensa certificate that is a lie. He is not a Mensa member. That certificate is a lie."
Curtis acknowledges posting a fake Mensa certificate on Facebook, but says it was an online trap set up for Dutschke because he believed Dutschke was stalking him online. He knew Dutschke also claimed to be a member of the organization for people with high IQs. Dutschke had a Mensa email address during a legislative campaign he mounted in 2007.
Dutschke started a campaign to prove him a liar, Curtis said, and allegedly harassed him through emails and social networking.
Curtis said the two agreed to meet at one point to face off in person, but Dutschke didn't show up.
"The last email I got from him, was, 'Come back tomorrow at 7 and the results of you being splattered all over the pavement will be public for the world to see what a blank, blank, blank you are.' And then at that point, I knew I was dealing with a coward," Curtis said.
