Here's A Clue, Sherlock, Don't Light Off Fireworks In Your House

From the LVRJ:
A fire that caused $150,000 in damage and displaced a family of five in the southwest valley Tuesday night started after a teenager played with fireworks in the home, Clark County officials said.
Clark County firefighters responded to the blaze at a two-story home at 10437 Mulvaney Circle, near Cactus Avenue and Interstate 15. The fire was knocked down by 7:18 p.m.
Fire officials deemed the blaze accidental and attributed it to "careless misuse of fireworks." Flames damaged the second floor and roof of the home.
