'Pizzagate': How a WikiLeaks-fuelled conspiracy theory led to gunfire at a D.C. restaurant

The bizarre rumours began with a leaked email referring to Hillary Clinton and sinister interpretations of pizza parties. It morphed into fake online news stories about a child sex trafficking ring run by prominent Democrats operating out of a Washington, D.C., restaurant.

On Sunday, it culminated in violence when police say a North Carolina man fired an assault rifle inside the Comet Ping Pong restaurant as he attempted to "self-investigate" the conspiracy theory known in the Twitterverse as "Pizzagate."

No one was hurt and the man was arrested. But the shooting alarmed those from neighbouring businesses all the way to the White House about the real life dangers of fake news on the internet. One of those people posting on the conspiracy theory is the son of president-elect Donald Trump's proposed national security adviser.

There is no physical evidence of this trafficking ring, no police investigation and no victims have come forward.

On Monday, White House spokesman Josh Earnest, when asked about the shooting, said, "There's no denying the corrosive effect that some of these false reports have had on our political debate, and that's concerning in a political context. It's deeply troubling that some of those false reports could lead to violence."

N.C. man arrested

Edgar Maddison Welch, 28 of Salisbury, N.C., was arrested Sunday afternoon outside the popular eatery in an affluent neighbourhood of the nation's capital, police said.

At his initial appearance Monday in D.C. Superior Court, Welch was ordered held pending a hearing scheduled for Thursday. The public defender he was assigned didn't immediately respond to an email seeking comment.

Court records made public Monday state Welch fired an AR-15 assault rifle multiple times inside the restaurant but later walked out with his hands up and unarmed, leaving his weapons inside. He told police "he had read online that the Comet restaurant was harbouring child sex slaves and that he wanted to see for himself if they were there."

He said he "was armed to help rescue them" and "surrendered peacefully when he found no evidence that underage children were being harboured in the restaurant."

Welch was charged with multiple counts, including assault with a dangerous weapon. Authorities recovered an AR-15 assault rifle and a handgun from the restaurant, court documents show. Police said an additional weapon was recovered from his vehicle.

One of Welch's friends told the Washington Post she doesn't think he intended to shoot anyone.

"He most likely really believes the conspiracy theory," said Kathy Sue Holtorf, 29, who lives in California and works as a film producer. "He's a good guy with the best of intentions. He probably saw himself as more on a hero mission to save children than anything else."

Holtorf produced a nine-minute short called Mutethat was written by Welch and they both appeared as victims of vampires in a slasher movie. She said Welch dabbled, but "never wanted to become an actor." Holtorf described Welch as "a well-educated man" and "not a conspiracy nut," saying he would talk about his daughters and how proud he was of them.

His aunt, Tajuana Tadlock, described Welch to the Washington Post as passionate and tenderhearted and a person who loves his family and his children. She said the family hasn't been able to talk to him so they don't know "what got him to this level."

"Maddison is a sweet young man with a big heart," said Tadlock. "We are all in shock right now. We are still trying to get our minds around what happened. This is totally out of character for him."

Murky origins of 'pizzagate'

The precise origins of the conspiracy theory Welch said he went to investigate are murky, though it seems to have started gaining momentum in the week before the election.

Some elements trace back to hacked emails from Clinton Chief of Staff John Podesta that were released by WikiLeaks that refer to pizza parties, with online commentators speculating that "pizza party" is a code word for something more nefarious.

By Nov. 3, Comet Ping Pong so named because patrons can play ping pong on tables in the back of restaurant had been pulled into the conspiracy due to leaked emails between Podesta and Comet's owner, James Alefantis, where the pair discuss a party fundraiser held at the restaurant.

"Let me state unequivocally: These stories are completely and entirely false, and there is no basis in fact to any of them. What happened today demonstrates that promoting false and reckless conspiracy theories comes with consequences," Alefantissaid in a statement Sunday night.

Trump adviser's connection

At least one person who isn't ready to give up on the conspiracy theory is prominently connected to Trump's transition team.

Michael Flynn Jr. is an adviser to his father, Michael Flynn, whom Trump selected to serve as national security adviser. Flynn Jr. has posted numerous tweets about the Pizzagate conspiracy theories.

Flynn Jr., who has accompanied his father to presidential transition meetings inside Trump Tower and lists thepresidential transition website as part of his Twitter bio, tweeted Sunday night that, "Until #Pizzagate proven to be false, it'll remain a story."

Vice-president-elect Mike Pence said Flynn Jr.has no role in the president-elect's transition

The senior Flynn has also tweeted false stories about Clinton, including one linking her and her staff to sex crimes,an investigation by Politico has revealed.

Support for Comet Ping Pong

On Monday, at an address listed for Welch in Salisbury, a woman drove out as a reporter was approaching and asked him to leave. She then hammered a "no trespassing" sign on a stand by the private driveway.

Comet Ping Pong was closed Monday, but neighbours brought flowers and cards to the storefront saying "We support Comet" and "we love you and stand by you."

Wiktoria Skrzypinska lives a few blocks from Comet. She said she had heard the rumours about Comet but was shocked to learn that somebody had become so enmeshed in the conspiracy theory to enter the restaurant with an assault rifle.

"I guess we all knew it was fake. It was so obvious, I didn't even bother with it," she said.
