A man who died in a house explosion six months ago outside the nation’s capital deliberately detonated gasoline canisters in his basement that caused the blast, authorities said Friday.
Arlington County police in Virginia went to the home of 56-year-old James Yoo on Dec. 4 because he was firing a flare gun from the back of his duplex into a nearby school and park, police said Friday at a news conference announcing the cause of the explosion.
