As we move into the last week of what has been one of the most unbalanced and violent presidential election in modern political history, a string of arsons at early voting sites in the Pacific Northwest has local and federal law enforcement searching for a culprit. It is undoubtedly another side effect of what election security experts have called for an increased “threat environment”.— a fancy term that seems to be short for: Americans are losing their minds, and it’s getting pretty hairy out there.

On Monday morning, someone drove to a ballot box in Portland, Oregon and applied an “incendiary device” on her side. Then they left. Not long after, around 3:30 AM, Portland police responded to reports of a fire nearby and found the cassette burning. Less than an hour later, a similar incident happened in the nearby city of Vancouver, Washington, where police found another Dropbox on fire. Again, a “suspicious device” was found lying on the ground next to him.

Police also suspect the incidents are related another firewhich took place in Vancouver almost three weeks ago on October 8th. In this case, the police were again called to put out a fire at a ballot box. A nearby homeless shelter had to be evacuated for safety reasons.

Local outlet KGW reports that authorities believe the Vancouver fires destroyed “hundreds” of ballots. The Portland fire destroyed only three. Local outlet KGW rEPORTS that the FBI is now working with local police to investigate the three incidents.

“We don’t know the motive behind these acts,” Portland Police Bureau Deputy Chief Amanda McMillan said. in a press release. “We know that such acts are targeted and they are intentional, and we are concerned that that intentional act is trying to affect the electoral process. We are dedicated to stopping this type of behavior.”

“We take the safety of our election workers seriously and will not tolerate threats or acts of violence that seek to undermine the democratic process,” Washington Secretary of State Steve Hobbs said in a separate statement. press release. “We strongly condemn any acts of terror that seek to disrupt legal and fair elections in Washington State. Despite this incident, I have full confidence in our county elections official’s ability to keep Washington elections safe for all voters.”

The good news is that police appear to have caught a glimpse of the vehicle they believe was involved in the arson. It was an image from the security footage of the “suspicious vehicle”. released to the public Monday. The car is described as a “2001-2004 black or dark Volvo S-60.” Police said the vehicle did not appear to have a front license plate, but did have a rear plate that authorities were unable to decipher.

Vancouver officials encouraged anyone who thinks a ballot may have been destroyed in Monday’s fire to contact the city’s elections division (if that happens to be you, you can call 564-397-2345 or email (protected by e-mail)). Those Portlanders who are concerned they may have been affected can call 503-988-6826. Even easier, many governments allow voters to see if their vote has been received by their local government. For Washington, voters can visit votewa.gov to track their return status. KGW reports: “If a returned ballot is not marked ‘received,’ voters may print a replacement ballot or visit the elections department, located at 1408 Franklin Street in downtown Vancouver, for a replacement ballot, office of the secretary of state.”
