A husband and wife who went on a deadly shooting rampage in Las Vegas had anti-government beliefs.

They were happily married and unhappily American.

Six months ago, Jerad and Amanda Miller left home in Indiana on a cross-country road trip with their two cats to start a new life in Las Vegas. Amanda, 22, had a part-time job at Hobby Lobby; Jerad, 31, dressed up as comic book heroes like Thor and Captain America for tips from tourists.

"I found my freak," Amanda said lovingly of her lanky husband, whom she had married in a September 2012 ceremony beside an Indiana cornfield. On Facebook, she posted doting messages: "You are the best. I said 'Until Death Do Us Part,' and I mean it." A photo on her Facebook page featured the couple dressed as comic book characters the Joker and Harley Quinn.

Jerad and Amanda Miller's young marriage ended Sunday in a barrage of gunfire after the couple, shouting messages of antigovernment revolution, fatally shot two police officers in an eastern Las Vegas pizzeria and, minutes later, killed a man in a nearby Wal-Mart who tried to stop their rampage.

As officers closed in, the pair barricaded themselves in the back of the store. Amanda Miller turned her gun on her husband and shot him several times, police said, before putting the gun to her own head and pulling the trigger.

By the time a SWAT team found their crumpled bodies, Amanda Miller was taking her final breaths.

The bizarre events Sunday in this unglamorous part of town — known more for its box retail outlets than glitzy casinos — plunged the Las Vegas Metropolitan Police Department into sorrow and anxiety as investigators tried to discover why two uniformed officers sharing a quiet lunch had been singled out as targets.

The day marked a culmination of sorts for Jerad Miller, who had apparently been fantasizing about a libertarian armed revolution for more than a year, and a worse one for Amanda Miller's parents, who had begged their daughter not to marry the man obsessed with government conspiracies.

"She was my sunshine and now she's gone," said her father, Todd Woodruff, 48, of Lafayette, Ind., his hand shaking as he held a cigarette. "And I just don't think that I'll be able to get over it."

The beginning

Amanda Woodruff met her future husband in her hometown of Lafayette, at the flea market where Miller worked, her father said. Miller, who had long hair and a flat drawl, was nine years older than Woodruff. He was a convicted drug dealer and car thief who got into political fights with his family on Facebook and struggled to meet his various parole conditions.

Woodruff was a good student who played violin for the orchestra at Jefferson High School, her father said.

On May 2, 2011, the couple made their relationship Facebook official.

Only a few weeks later, Amanda Woodruff went on a tirade on the social media site: "To the people in the world ... your lucky i can't kill you now but remember one day one day i will get you because one day all hell will break lose and i'll be standing in the middle of it with a shot gun in one hand and a pistol in the other."

The reason for the outburst wasn't clear. But it seemed her new beau was similarly inclined. Post after post on his Facebook page expressed disgust for American consumer culture and called for an armed revolution to protect the cause of personal liberty from the Republicans and Democrats in power.

He resented his marijuana arrests and often wondered why there needed to be a government at all, at one point earnestly comparing the judge in one of his cases to a Nazi.

A Seattle Seahawks fan, Jerad Miller fantasized about what would happen if famous football players such as Seahawks quarterback Russell Wilson and Denver Broncos quarterback Peyton Manning announced they wouldn't play in the Super Bowl in protest of government agencies such as Homeland Security and the National Security Agency.

"How many people do you think would wake up? Surely there would be riots, all hell might break lose lol," Miller wrote.

Todd Woodruff wasn't impressed. "He was into all this 'patriot nation' and conspiracy theory stuff, and the next thing I know her phone was getting shut off and she was getting isolated from us," he said. "The whole world was against him and he was just, he was just nuts. He got kicked out of his family's house; they wouldn't talk to him. It was just that far out."

Amanda Miller seemed aware of how uncomfortable her husband made some people. "I love this man with every inch of me and I know that some people don't like him or approve of our relationship and that's ok," she wrote on her Facebook page. "It's our love and I know it's weird and I know it's different but that is what makes it so special."
