The man was transported to Jamaica Hospital and succumbed to his wounds. Police say the gunman also fired randomly at a crowd of people on 108th Street, but did not strike anyone.

During a press conference, authorities said that the shooter used an illegal scooter without a valid license plate. Assistant Chief Joseph Kenny also said that the attack appeared to be random.

"We don't know the motive…If you look at the demographics and pedigree of the victims, they're all different," Kenny said. "At this time, video shows that he's not targeting anybody. He's not following anybody as he's driving on his scooter, he's randomly shooting people."
