"Witnesses to the shooting described the gunman as a short, dark-skinned man with a heavy build wearing a green construction vest and gray sweatshirt."

"The van was spotted in front of an apartment building on West 3rd Street just off the Kings Highway shopping strip in the Gravesend neighborhood, the senior law enforcement official said. The official also said that a gun had been found inside the subway station. The authorities have not released a suspect’s name, nor a motive for the attack. But another high-ranking police official said that the attack appeared to have been planned and showed no signs of having stemmed from something spontaneous like a dispute on the train. As the shooting unfolded and the doors of the N train opened, sending smoke billowing through the station, fearful riders fled, many of them hurrying onto an R train sitting across the platform. Subway seats and cars were streaked with blood as people called for help."
