ARLINGTON, VA. • The owner of a Virginia house that exploded as police tried to execute a search warrant is believed to have died in the blast, officials said Tuesday, as details emerged about numerous grievances he expressed against neighbors and others on social media and in lawsuits.

James Yoo, 56, was identified by Arlington County Police Chief Andy Penn at a news conference as the person whose actions brought police to the Arlington home after he fired a “flare-type gun” from inside the house into the neighborhood more than 30 times.

Penn said police responded to the house about 4:45 p.m. Monday after receiving reports of shots fired. When attempts to communicate with Yoo were largely unsuccessful, police obtained a search warrant. As officers breached the door to enter the home, the suspect fired multiple gunshots from within the house, Penn said. He said it wasn’t clear where in the house the shots were coming from or what the suspect was firing at.

Soon after that, just before 8:30 p.m., the house exploded, shooting flames and debris into the air in a blast that was felt for miles.
