LAS VEGAS -- Metro Police investigators are sifting through clues in accused shooter Jerad and Amanda Miller's past.
They're hoping to find a motive for their shooting spree.
The I-Team has been looking through those same clues about the shooter's beliefs and criminal past.
Metro Police announced Monday that after Jerad Miller and his wife murdered two police officers, they announced "the revolution was coming."
As self-described militias gathered at Cliven Bundy's Bunkerville ranch in April, Jerad and Amanda Miller joined them. Jerad Miller posted online that he and his wife quit their jobs and sold everything to buy supplies.
Television station KRNV from Reno aired an interview with Miller from Bundy ranch.
"I feel sorry for federal agents that want to come in here and push us around or anything like that. I really don't want violence towards them, but if they're going to come bring violence to us, well, if that's the language that they want to speak, we'll learn it," Miller said.
Miller wrote that because of his past felonies, militia members kicked him and his wife out of camp. Miller added "how dare you ask for help and shun us dedicated patriots."
Cliven Bundy's son Ammon confirms Jerad and Amanda Miller were at their ranch. Ammon says the state militias asked them to leave because of "radical conduct" and "things they were saying."
Ammon added that they've contacted the Clark County Sheriff's Department to express their willingness to cooperate with their investigation.
Jerad Miller posted political statements on social media several times each week. It is difficult, if not impossible to put a political label on Jerad Miller.
He does not appear to follow the sovereign citizen or anarchist movements. A fellow Bundy supporter tells the I-Team that Jerad talked of trying to incite an Indiana white-supremacist group to shoot police.
Miller attended political events, supporting libertarian and American Independent Party candidates. Miller believed a coming police state would bring concentration camps for Americans.
Metro Police say he draped a Gadsden or "don't tread on me" flag on the bodies of the two officers he and his wife murdered.
That is a symbol commonly used by people protesting the federal government. In 2012, Miller posted, "I do not want to kill cops. I'm not advocating doing it. I'm not going to go out and find a cop and shoot them. But, if they come to take me away, I would rather die than go to jail or a FEMA re-education camp, when I have done nothing to hurt another human being."
In October 2013, Miller claimed he just discovered Indiana issued a warrant for his arrest. Records show his first crime was stealing a car shortly after graduating high school in Kennewick, Washington.
He served a few months jail time for a series of marijuana arrests and one charge of battery. After his 2012 wedding, Jerad and Amanda Miller came to Las Vegas and worked as street performers.
Amanda acted out as Harley Quinn from the Batman comics and Jerad was The Joker.
