Deb Bartley, a friend of Van Spronsen’s for about 20 years, described him as an anarchist and anti-fascist, and she believes his attack on the detention center was intended to provoke a fatal conflict.
“He was ready to end it,” Bartley said. “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 and other friends of Van Spronsen got letters in the mail “just saying goodbye.” He also wrote what she referred to as a manifesto, which she declined to discuss in detail but predicted would be taken by authorities.
Maru Mora-Villalpando, an activist with the group La Resistencia, which has frequently protested the conditions at the detention center and broader immigration policy, said she did not know Van Spronsen. Nor was La Resistencia involved with the June 2018 protest at which he was arrested, she said.
Van Spronsen had worked as a self-employed carpenter and contractor, according to court documents. He was also a folk singer, playing shows on Vashon Island and around the Seattle area.
The 2018 protest involved about 160 people outside the detention center. About 40 people blocked a police car that had arrived, prompting the officer to call in backup; about 25 officers responded.
In court documents, Van Spronsen was accused of lunging at a police officer’s neck to help free a 17-year-old protester who was being detained. Van Spronsen refused to comply with officers’ orders, and as he was led through a crowd of protesters, police said he tried to pass the baton to another protester. Van Spronsen was punched in the face at least once during the altercation. Nine other people were arrested as well.
He ultimately pleaded guilty in Pierce County Superior Court to one count of obstructing an officer, a gross misdemeanor, and received a one-year deferred sentence in October, according to court documents, which labeled him indigent. He had no previous criminal history, according to court records.
