Has the Aryan Brotherhood launched a war against Texas? That's the question law enforcement authorities are wrestling with in Kaufman County, some 20 miles southeast of Dallas, after the brazen weekend slaying of a district attorney and his wife. The killings come just two months after another prosecutor was shot execution style by unknown assailants as he walked from his car to the county courthouse. The Texas branch of the white supremacist group has been eyed in connection [with these crimes] because more than 30 members and at least four of its most senior leaders were busted in a federal takedown late last year. On November 30, an investigation run by local law enforcement, the FBI, and the ATF indicted key members for carrying out murders, attempted murders, conspiracies, arsons, assaults, robberies, and drug trafficking as part of an enterprise that goes back to at least 1993. Mike McLelland, the prosecutor killed alongside his wife, Cynthia, this weekend, had been under around-the-clock protection until shortly before the slaying. Some experts familiar with the Aryan Brotherhood of Texas caution that some aspects of the killings don't bear the trademarks of the group.
