A witness, who is not named in the document, told investigators that Dutschke once said years ago that he knows how to make poison that could be sent to elected officials and "whoever opened these envelopes containing the poison would die."
Judge Holland dismissed a civil suit Dutschke filed in 2006 against the witness, who accused him of making sexual advances toward the witness's daughter, the affidavit said. In April, Dutschke pleaded not guilty in state court to two child molestation charges involving three girls younger than 16. He also was appealing a conviction on a different charge of indecent exposure. He told AP that his lawyer told him not to comment on those cases.
The lawsuit isn't Dutschke's only connection to Holland. She is part of a family that has had political skirmishes with him.
Her son, Steve Holland, a Democratic state representative, said his mother encountered Dutschke at a rally in the town of Verona in 2007, when Dutschke ran as a Republican against Steve Holland.
Holland said his mother confronted Dutschke after he made a derogatory speech about the Holland family. She demanded that he apologize, which Holland says he did.
Dutschke's MySpace page has several pictures with him and Wicker. Republicans in north Mississippi say Dutschke used to frequently show up at GOP events and mingle with people, usually finding a way to get a snapshot of himself with the headliner.
The first suspect accused by the FBI, Curtis, also had also had ties to Holland. Curtis was arrested on April 17 at his Corinth, Miss., home, but the charges were dropped six days later. After his arrest, Curtis said he was framed and gave investigators Dutschke's name as someone who could have sent the letters, the affidavit said.
Curtis has said he knows Dutschke and they feuded over the years, but he wasn't sure what caused it.
