Here is what we know about James Yoo, the man linked to the Arlington, Virginia home explosion.
Police responded after there were reports of a flare gun being fired from the home.
James Yoo was listed on public records as the one living at the property.
Yoo was racist against white people in LinkedIn posts, claiming they had been stalking him since the 1990s: "This is how White people operate."
Yoo posted wild LinkedIn posts showing he hated the government/police and thought his neighbors were spying on him.
Yoo covered his windows with aluminum foil.
Authorities have still not released the name of the suspect or if anyone else was in the home at the time of the incident.
