MISSION, Kan. — About 50 college campuses across the United States in recent weeks received hoax calls about armed gunmen and other violence, laying bare the challenges of detecting fake threats quickly to prevent mass panic.
hiding under desks, only to find out later it was a false alarm. Last week, several locked down or canceled classes after receiving threats, at a time when the fatal shooting of conservative activist Charlie Kirk at a Utah college had campuses on edge.
In other cases, schools figured out early that something was amiss, but even then it took time and resources.

The is to get authorities, particularly a SWAT team, to respond to an address.
Some of the earliest swats stemmed from online gaming disputes. Such incidents later were connected to nihilistic groups, which often conduct the calls in mass batches, trading tips in online forums on how to avoid detection.
The FBI said swatting is on the rise. Since a center was created in 2023 to gather details on such incidents, hundreds of law enforcement agencies voluntarily submitted thousands of incidents, the FBI said.
The problem is so prevalent, the U.S. on how to spot hoax calls. Clues include if the caller can’t answer follow-up questions about their phone number or current location, or mispronounces names.
Purgatory, a group affiliated with The Com, a loose network of online threat actors, was linked to some recent swats, according to reports from the , an Alabama-based nonprofit that tracks extremist groups online, and the nonprofit Center for Internet Security and Institute for Strategic Dialogue. The FBI declined to comment on the reports.
On more than two hours of livestreams captured by the nonprofits and provided to The Associated Press, the caller’s friends can be heard in the background laughing, belching and taking breaks to rap.

Last month at Kansas State University, there were clues from the start that something was amiss.
The first red flag was that it wasn’t a 911 call, said Major Daryl Ascher of the Riley County Police Department. Police declined to provide their own recording of the call, but Ascher confirmed many of the details.
Emergency calls are geolocated, meaning someone calling 911 outside the targeted area won’t get through because it will be directed to the dispatch center closest to their location. Swatters instead resort to calling non-emergency police numbers.
“That should be a dead giveaway,” said Don Beeler, chief executive officer of TDR Technology Solutions, which tracks swatting calls and offers technology to prevent them. “You’re not going to look it up if you are in an emergency. That’s just not how the human brain works.”
He said that if its system detects a suspicious call like that, it is transferred to an automated recording that tells the caller to hang up and dial 911.
On the technical side, halting calls made using voice over internet protocol technology from being made from behind virtual private networks would stop most swats, said Keven Hendricks, a cyber crime expert who teaches law enforcement about investigating swatting. He’s been swatted, himself.
The next clue was that the swatter got the Manhattan, Kansas, school’s name slightly wrong, calling it Kansas City State University, referencing a city about 120 miles away.
“Obviously, if you were from Manhattan or attending a university, you would know the name of the university,” Ascher said.
As a giggling throng listened on messaging platform Telegram, the swatter then described a man armed with an AR-15 prowling the university’s library, a description nearly identical to the calls flooding other university towns. The gunfire that peppered the call also was a tip-off because it “sounded like it was from a TV,” Ascher said.
On the livestream, the clearly skeptical dispatcher asked why the caller couldn’t see the purported gunman when the shots sounded so close to him and why other 911 calls weren’t flooding in.
“I’m not sure ma’am. I’m not sure if they have a phone or not,” the caller answered.
Officers still were dispatched to the library. Ascher provided no details on how many or their tactics, but said dispatchers kept them informed of the potential it was a hoax.
The worry is that hoaxes will create complacency at campuses where active shooter alerts and drills became a regular part of life.
“I hope we’re not desensitized enough to this enough to the point where we don’t take these alerts seriously anymore,” said Miceala Morano, 21, a senior journalism major who took cover after a recent threat at the University of Arkansas.
