Two Iowa men, one from Ames and another from Boone, were arrested in Boston after attendees at a Pokemon World Championship event alerted authorities to what they believed were threats. 

Boston police said Kevin Norton, 18, of Ames, and James Stumbo, 27, of Boone, were arrested last Thursday after public safety personnel at the Hynes Convention Center in Boston, where the event is being held, alerted police of the threats.

Stumbo had posted pictures on Facebook of two rifles on top of the trunk of a car with the caption “Kevin Norton and I are ready for worlds Boston here we come!!!”

The men had also posted on social media about the Boston Marathon bombing and Columbine, KCCI reported.  

Police were told the men drove from Iowa and may be in possession of firearms. The men were stopped trying to enter the event and could not produce a license to carry the weapons, the Boston Police said. 

Officers seized their vehicle and released the men, pending a search warrant. When the search warrant was obtained and a search was conducted, detectives found a 12-gauge Remington shotgun, an AR-15 rifle, several hundred rounds of ammunition and a hunting knife. An arrest warrant was issued, and the suspects were later arrested at a hotel in Boston. 

Mayhem Collectables, a comic book and game store on Lincoln Way in Ames, said Monday that the two had been regulars at the store in the past but had not been to the store in several months. 

A worker from Mayhem said they were “shocked this would happen,” and that they always worked to foster a strong relationship with attendees at local Pokemon events the two would attend.

According to Norton’s Facebook page, he worked as a volunteer at ISU’s Reiman Gardens and attended Ames High School from 2011 to 2015.

Both are charged with unlawful possession of a firearms, unlawful possession of ammunition, and other firearm related charges, according to the Boston Police.

KCCI reported that the men are being held without bail.
