As word spread through the South Riverdale neighborhood were Mr. Yang was killed, residents expressed shock as witnesses shared their accounts of the tragedy.
"About 12:15, 12:30, there was a loud noise that sounded like a firecracker. I did not think to look," said a nearby resident who witnessed the aftermath of the shooting.
"A few seconds later, I heard footsteps — loudly — I peered out, noticed a man running up 232nd Street on the sidewalk cut over to the center of the street. When he bent down to pick someone up by the arm is when I noticed that it was a person. He put the person back down, casually strolled up to the top of 232nd, made a right on Cambridge, casually stepped into a vehicle. The vehicle casually drove away."
The witness said that when the man approached Mr. Yang's facedown body, he kicked the victim's arm back onto the ground. That was when the witness dialed 9-1-1.
Then, the witness said, the man got into the passenger side of a vehicle that was double parked in front of the no-parking sign on Cambridge Avenue, to the right of the West 232nd Street intersection.
When police responded, they said they found Mr. Yang unconscious. EMS brought him to Columbia Presbyterian Hospital, where he was pronounced dead on arrival.
The suspect was wearing a hooded sweatshirt and took off in a silver minivan with the victim's phone, police said.
This is the first alleged homicide to take place within the 50th Precinct this year.
The neighbor who witnessed the aftermath of the shooting, said that when she heard the loud pop she assumed it was the sound of a firecracker because kids who live nearby often set them off.
Another neighbor, who was playing a late-night game of scrabble, did not even interrupt her game.
"I don't know what a gunshot sounds like," she said.
