It was no accident.
On Labor Day 2013, a 6-alarm fire destroyed a warehouse at 801 South Pickett St., Alexandria - one of the largest blazes in Northern Virginia in more than decade.
Firefighters from the City of Alexandria, Arlington County, Fairfax County in Virginia, along with Prince George's County, Maryland, battled the flames on the Labor Day holiday.
Crews contended with a broken water main near the blaze and a roof collapse.
There were no serious injuries.
The Sept. 2 incident was one of the largest for Northern Virginia's firefighters since the Pentagon attack in 2001.
On Sept. 10, Alexandria Fire Chief Adam Thiel announced investigators concluded the fire was deliberately set. "We ruled out any of the accidental causes," said Thiel, quoted by WJLA Channel 7. "It was not an accidental fire."
