On Saturday, an armed man approached an ICE detention facility and started throwing incendiary devices at it. He was shot and killed by officers.
Now his manifesto has been discovered, and in it he identifies himself as a member of the anti-Trump Antifa group.
The Department of Homeland Security has classified some of the actions by the anarchist group as “domestic terrorist violence,” according to Politico. 69-year-old Willem Van Spronsen appeared to bolster that classification when he attacked the Northwest Detention Center, which is run by U.S. Immigration and Customs Enforcement in Tacoma, Washington.
According to the Seattle Times, Van Spronsen was armed with a rifle when he approached the facility and threw flaming objects at buildings and ignited one vehicle. Police say he unsuccessfully tried to cause a propane tank to explode as well.
Four police officers responded and opened fire. It was unclear at 1:45 p.m. Eastern on Monday if Van Spronsen fired at them. He died after being hit multiple times.
Deb Barley, a longtime friend of Spronsen, believes the man wanted to die.
“He was ready to end it. I think this was a suicide. But then he was able to kind of do it in a way that spoke to his political beliefs … I know he went down there knowing he was going to die,” she said.
A manifesto discovered by police supported Barley’s belief.
"I regret that I will miss the rest of the revolution," Spronsen wrote, according to Fox News. "Doing what I can to help defend my precious and wondrous people is an experience too rich to describe. I am Antifa."
He also described ICE detention facilities as "concentration camps."
The Seattle Antifascist Action group praised the man’s actions on Facebook, calling him “yet another martyr in the struggle against facism.”
“He was kind and deeply loved by many communities; we cannot let his death go unanswered,” they also wrote. “May his death serve as a call to protest and direct action.”
Last year, Spronsen was arrested for wrapping his arms around the neck of a police officer who was detaining a protester. He pleaded guilty to obstruction.
