Las Vegas police said on Monday the married couple who shot two police officers and another person before taking their own lives had an anti-government, anti-police mentality. The two, identified as Jerad Miller and his wife Amanda, subscribed to "militia and white supremacist" ideology, authorities said. Officials also said the Millers left a swastika and a "Don't Tread On Me" flag on the body of one of the two police officers they killed. They had been kicked off a Nevada ranch where anti-government protesters faced down federal agents earlier this year because they were "very radical," the son of rancher Cliven Bundy told The Associated Press.
