Police in Fairfax County say a shooting Saturday afternoon at Tysons Corner Center that sent panicked shoppers fleeing was the result of “beef” between two rival D.C. crews who encountered each other on the mall’s second floor.

The two crews — the 37th Street Crew and the Simple City Crew, which both operate out Southeast D.C., “were engaged in a beef,” Fairfax County Police Chief Kevin Davis said during a news conference Thursday.

“It started with words; it ended up with a pushing and shoving match and then a display of a firearm,” Davis said. “And then, just minutes later, three shots ring out … three shots in a crowded mall.”
