White supremacist Matthew Hale, who is due to be sentenced for a failed plot to kill federal judge Joan Lefkow in Chicago, has denied any involvement in the recent murder of Lefkow's mother and husband. Hale issued a statement from prison through his mother. "I want the perpetrator caught or prosecuted," Hale said. "There is simply no way that any supporter of mine would commit such a heinous crime", Hale said. "I only hope they sincerely wish to apprehend this animal instead of railroading the innocent. Only an idiot would think that I would do this." FBI agents investigating the slayings have been focusing on white supremacist groups, and a federal grand jury was convened to issue subpoenas, the "Chicago Tribune" reported. Judge Lefkow arrived home after work on Monday to find the bodies of her husband (64) and her mother (89) in the basement. Both had been shot dead.
