Quite possible. From the article:
A house in Arlington, Virginia, exploded Monday night only minutes after police posted on social media about a suspect setting off a flare gun inside a home.
Around 4:45 p.m., Arlington County police responded to the 800 block of North Burlington Street for reports of shots heard. In their initial investigation, officers determined from nearby residents that a suspect discharged a flare gun 30 to 40 times from inside his home into the neighborhood, according to police in [a statement released early Tuesday.]
