The shooting occurred at a dance studio on Garvey Avenue sometime after 10 p.m., according to several witnesses. Internal police communications said there had been some fatalities.
They said there was a man with a semiautomatic gun in the area. The shooter, they said, had multiple rounds of ammunition on him, so that once his ammunition ran out he reloaded, Choi said.
The shooter was carrying a long gun and appeared to fire indiscriminately, his friends told him. “They don’t know why, so they run,” he said.
