According to court documents, Kaleb Cole is the leader of a small, but dangerous white supremacist group called "Atomwaffen."

SEATTLE — Police seized military-style firearms from an avowed neo-Nazi in Snohomish County in what is believed to be a first-of-its-kind case in Washington state.

“We actually, I firmly believe, prevented a massacre,” said Seattle City Attorney Pete Holmes, whose office was involved in the investigation.

Records filed in King County court show officers from the Arlington and Seattle police departments seized five military-style rifles, three pistols, and other gun parts from a residence on Jordan Trails Road in Arlington.

According to court documents, the weapons belong to Kaleb J. Cole, who is the suspected leader of The Atomwaffen Division in Washington state.

Authorities claim Cole has been amassing firearms and training with weapons in western Washington. Online videos show Atomwaffen members firing guns and moving through rooms at “devils tower,” a graffiti-scarred building at an abandoned cement plant near the City of Concrete.

“This is a hate-filled human being but one who, unfortunately, possesses a large number of weapons,” Holmes said.

Cole is not charged with a crime but is named in an Extreme Risk Protection Order (ERPO) filed earlier this month in King County court. In the civil paperwork, prosecutors and the FBI convinced a judge that “Kaleb Cole poses a serious threat to public safety by having access and possession to firearms and a concealed pistol license.”

The judge issued an order requiring Cole to surrender all firearms to the police.

Atomwaffen, which is a German for “atomic weapon,” is a small but extreme organization that seeks inspiration from Adolph Hitler and Charles Manson, who ordered mass murders to attempt to trigger a race war.

Its white supremacist members claim they will not start the war, but they are arming themselves in preparation.

Atomwaffen members have been charged in five murders in other states.

The FBI has clearly been watching Cole, although a spokesperson for the bureau’s Seattle office declined to comment.

Documents filed in court show that Cole traveled to Eastern Europe in December of 2018 on a trip to honor the sites of some of World War II’s most horrific scenes.

Cell phone photos retrieved by Customs and Border Patrol agents when Cole re-entered the U.S. show him posing in front of the Nazi death camp Auschwitz. In the photos, Cole is holding up the Atomwaffen flag at other locations, and other photos show him holding guns.

“Cole has been permanently banned from entry into Canada as a result of his [admitted] membership/affiliation with the Atomwaffen Division,” the Border Patrol report stated.

Earlier this year, the Seattle FBI approached Seattle/King County’s Regional Firearms Enforcement Unit operated by the Seattle City Attorney, King County Prosecutor, and Seattle police.

Agents sought an ERPO to disarm Cole, but the federal government has no such tool.

“The fact is the federal government came to us. There’s no other mechanism like our firearms unit that’s in existence. There’s no one else in the state that’s doing this,” said Holmes.

It’s the first time the Feds have sought an ERPO in Washington state, and it’s believed to be one of the first instances in the nation.

King County Prosecutor Dan Satterberg, whose deputy prosecutor Kim Wyatt argued the ERPO case before the judge, said the order to surrender guns is the right tool when law enforcement does not have enough evidence to file a criminal charge.

“In this case, the joint terrorism task force had assessed Mr. Cole and said he was somebody who was doing more than thinking and talking about his extremist, violent beliefs, but that he was actually acting on it,” Satterberg said.

Holmes said the case marks an important milestone since he started working with his domestic violence prosecutor, Chris Anderson, on the pilot project that formed the firearms enforcement unit.

That unit has now seized nearly 1,100 firearms since 2017, mostly from accused domestic abusers.

The fact the FBI recognized an ERPO’s ability to stop a threat is significant.

“We can actually prevent some of these massacres,” said Holmes.
