Arlington house explosion intentionally caused with up to 35 gallons of gas, investigators found

The stunning explosion that leveled a duplex in Arlington, Virginia, in December was intentionally caused by a resident who was found dead inside, investigators found.

James Yoo intentionally caused the explosion caught on video using up to 35 gallons of gasoline that he set ablaze, local and federal officials said at a news conference Friday.

The Dec. 4, 2023, explosion rocked a Northern Virginia neighborhood with a powerful blast and destroyed the home of a family who lived adjacent to Yoo.

Investigators determined that Yoo intentionally triggered the blast in the basement using gasoline in three containers, including one with a capacity of up to 20 gallons. He likely set the gasoline ablaze using a gun, flare gun, matches or a lighter, a U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) official said.
