Arlington, Virginia, officers were investigating shots fired and executing a search warrant when a house exploded.
Police posted about the suspect's flare gun activity on social media minutes before the explosion.
The suspect fired a flare pistol 30–40 times from inside the home toward the neighborhood, according to the inquiry.
While executing the warrant at night, the suspect inside the house fired multiple shots, causing the explosion.
The defendant may have fired a handgun at cops during the search warrant execution in addition to the flare gun.
The suspect is still missing, according to Arlington County Police public relations officer Ashley Savage.
Following the incident, WTOP's Dick Uliano reported a "acrid" smell and "smoldering ruins" in the roadway.
After evacuations, Arlington Fire & EMS reported a "structure fire" with control hours later.
