Moments after shots were fired, cameras showed a young man emerge from Westchester Avenue in Soundview. He placed the gun in his hand before walking off on the crowded street.
Empty shell casings littered the street - one person was hit by gunfire, and another was injured by shattered glass.
A man in a jacket or a dark vest arrived at the scene moments before the shooting. Cameras caught him before he pulled a mask up over his face on a warm autumn day. When shots were fired, the man ran away, and some of the people on the streets ran into stores to get away.
The 43rd Precinct tweeted out the suspect's picture, with a note on Monday night:
According the video, the man may have at least two friends who were with him that day. The investigation is ongoing.
