Curtis' attorney, Christi McCoy, said Saturday: "We are relieved but also saddened. This crime is nothing short of diabolical. I have seen a lot of meanness in the past two decades, but this stops me in my tracks. "
Dutschke and Curtis were acquainted. Curtis said they had talked about possibly publishing a book on an alleged conspiracy to sell body parts on a black market. But he said they later had a feud.
Judge Holland is a common link between the two men who have been investigated, and both know Wicker.
Holland was the presiding judge in a 2004 case in which Curtis was accused of assaulting a Tupelo attorney a year earlier. Holland sentenced him to six months in the county jail. He served only part of the sentence, according to his brother.
Holland's family has had political skirmishes with Dutschke. Her son, Steve Holland, a Democratic state representative, said he thinks his mother's only other encounter with Dutschke was 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.
On Saturday, Steve Holland said he can't say for certain that Dutschke is the person who sent the letter to his mother but added, "I feel confident the FBI knows what they are doing."
"We're ready for this long nightmare to be over," Holland told The Associated Press.
He said he's not sure why someone would target his mother. Holland said he believes Dutschke would have more reason to target him than his mother.
"Maybe he thinks the best way to get to me is to get to the love of my life, which is my mother," Holland said Saturday.
