A Wikipedia conference in Manhattan descended into chaos Friday morning when an unhinged Ohio man jumped on stage and pointed a gun at his own head.

Connor Weston, 27, allegedly clutched the loaded revolver as he declared, “I’m a non-contact pedophile. I want to kill myself” — prompting WikiConference staff to quickly tackle and disarm him before cops took him into custody, sources said.

“It was just adrenaline,” said one of the staffers who stopped the gunman.  “Since you’re on the trust and safety team you’re expected to do this . . . we’re not used to loaded weapons in the same room . . . we’re used to more prank behavior.” 

Weston — who wore a multicolored banner draped over his shoulders and a sign around his neck with the words “ANTI-CONTACT NON-OFFENDING PEDOPHILE” — was detained at the conference, which was hosted at Union Square’s Civic Hall on East 14th Street near Irving Place, sources said. 

“I think we handled it pretty well considering this was not an expected thing,” the worker who helped stop the incident added. “We’re expected to do that for every event but in a place like NYC you’re going to have more people and more chance of it.”

Weston is awaiting charges at the NYPD’s 9th Precinct.

No one was hurt, but the disturbing ordeal was enough to rattle witnesses and others inside the building. 

“It was surprising. One of the keynote speakers was presenting and then all of a sudden there was someone on the stage saying something about suicide,” one woman said. “I didn’t realize he had a gun but apparently he did. But the response was really fast: ‘get down, get out.’

“People were scared,” the witness added. 

Another woman, Karen Ganes, was taking a coffee break from an unrelated class on the fifth floor when alarms started blaring, alerting building occupants of someone with a gun on the second floor.

“They told us to go back into our classroom and lock the door,” Ganes said. “But it was glass. It was half glass. So we kind of went to the back where there was a wall there. 

Another woman threw herself onto the floor in fear, Ganes recalled. 

“I texted my sister, and she’s very spiritual,” she added. “She just said, ‘I’m praying for you. Let me know what’s happening.’”

Weston, from Dayton, had registered for the conference, which was being held in New York this year to celebrate the city’s 400th anniversary, according to the event page.

In a late June post on X, he explained that he is “fundamentally against adult/minor relations because I know that they are harmful.”

“I don’t have any ‘urges’ that I have to control, just like how most straight men don’t have the urge to rape every woman they meet,” he wrote. “Pedophilia is not a choice. I can choose to not harm minors, but I cannot choose to stop being attracted to them.”

A Wikimedia Foundation spokesperson said the conference will continue – though with extra security and police presence – after the gunman was cuffed.

“Participants at WikiConference North America are safe, and are continuing to gather together in community,” the rep said. “We appreciate the conference organizers and attendees who stepped in to help during the opening ceremony.

“The rest of the event will proceed as planned, and there will be additional security as well as law enforcement onsite for the entire event.”

“We are grateful to the event organizers and local law enforcement for their support.”
