The FBI served the warrant on Frazier Glenn (Cross) Miller's home in Aurora, Missouri the evening of April 13. That's the same day Miller allegedly opened fire, killing a man and his grandson outside the Jewish Community Campus in Overland Park, Kansas. A third person, a woman, was killed at the Village Shalom, a retirement community a short distance away.
Authorities said Miller allegedly fired at two other people, but missed.
According to the documents in the search warrant return, investigators were looking for phone, thumb drives, any documents about Village Shaloam - including directions, documents related to white supremacy, firearms and other evidence related to the shootings.
Among the documents found was a printout of the 2014 Kansas City Superstar Competition, the location and event where Miller killed a grandfather and his grandson who was singing in the competition.
Items seized in the search included books written by Miller, titled "A White Man Speaks Out", a copy of "Mein Kampf" by Adolph Hitler, ammunition, a computer, anti-Semitic newspapers and literature, an invoice for a 12-gauge shotgun and a printout of kosher places to eat.
A small note at the bottom of the search warrant shows Miller printed out a list of "kosher places to eat."
Computers were also seized from the home. What is on those computers will be revealed at some point in court.
In addition, there was a print out of directions to a synagogue.
The FBI also seized a folder titled "going underground and declaring war against the government."
Miller, 73, has a long history of anti-Semitic activities, including being a past Grand Dragon of the Carolina Knights of the Ku Klux Klan, according to the Southern Poverty Law Center.
