The aging founder of a white supremacy organization and three followers have been sentenced in Las Vegas federal court to prison terms for conspiring to send death threats to IRS agents and a Nevada judge. The four, members of a group that does not recognize the United States government, were convicted last October on 10 counts of attempting to interfere with administration of Internal Revenue Service laws and mailing death threats to federal agents and state Judge Earle White, who is black. The Rev. William Gale, 71, of Mariposa City, Calif., an emphysema victim confined to a wheelchair and a founder of the Committee of the States, was sentenced to one year and one day in prison. Patrick McCray of Las Vegas and Fortunato "Slim" Parrino of Mariposa County received similar prison terms. Mike McCray, identified by prosecutors as a moving force behind the Nevada Chapters of the Committee of the States, was sentenced to seven years in prison.
