 We've got an update on that big apartment building fire that took more than 100 firefighters to put out in southeast D.C. yesterday and led to many dozens of people not having a roof over their heads. This evening we learned the cause of the fire was young people playing with fireworks, Roman candles, that went off on a second-story balcony. Roman candles are illegal in D.C. Two apartment buildings were destroyed in the complex on Bowen Road off Suitland Parkway. Seventy people who live there have to find another home.
