The Mississippi judge who received one of the letters, Sadie Holland, is part of a family that has had political skirmishes with Dutschke. 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, though he's never worked for Wicker's campaign. 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.
"He would always hand his camera to somebody to get his picture made," longtime Republican Mike Armour of Tupelo said by phone Monday.
A woman described by a neighbor as Dutschke's wife arrived at their home Monday afternoon but covered her face and did not respond to a reporter as she walked from a green minivan into the house.
Rory Key lives just down the street from Dutschke's house. He said Dutschke came to his house while the FBI was searching the suspect's home asking for a drink and a snack.
He said the suspect was more upset than nervous. Key said he doesn't believe Dutscke committed the crime. He also said he didn't know him that well because Dustchke kept to himself.
