“
San Francisco police arrested DePape at the scene. He planned to take Speaker Nancy Pelosi
hostageand interrogate her. Prosecutors believed the attack to be politically motivated. DePape, a Canadian immigrant to the United States, had a history of
mental health issues and drug abuse. Before the attack, he had embraced various
far-right conspiracy theories, including
QAnon,
Pizzagate, and
Donald Trump's false claims of a stolen election in 2020. Online, he made conspiratorial, racist, sexist, and antisemitic posts, and pushed
COVID-19 vaccine misinformation. His blog also contained
delusionalthoughts. At his subsequent trial, DePape testified that he was motivated by conspiracy theories and had hatched a "grand plan" to target Speaker Pelosi and others.”

Looks like it was an immigrant with drug abuse issues that committed the crime. But not the immigrant you were hoping for since it was a white guy who committed the crime.
