"He almost had my sympathy until I found out that he was trying to blame somebody else," Dutschke said. "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 on the Internet.
He knew Dutschke also claimed to be a member of the organization for people with high IQs. Dutschke had a Mensa email address during his 2007 legislative campaign.
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.
Hal Neilson, one of the attorneys for Curtis, has said the defense gave authorities a list of people who may have had a reason to hurt Curtis and that Dutschke's name came up. Efforts to reach Curtis, his lawyers and his brother were unsuccessful on Wednesday.
Both men say they have met Wicker, and they each have a connection to Holland.
Authorities say the letters were mailed April 8, but the one sent to Holland was the only one to make it into the hands of an intended target. Her son, Democratic state Rep. Steve Holland of Plantersville, said his mother did a "smell test" of the envelope and a substance in it irritated her nose. The judge was not sickened by what authorities say was a crude form of the poison, which is derived from castor beans.
