Across the street, a man named Robert Mozer heard Genovese from his apartment. Looking out his seventh-floor window, he saw a man and a woman, sensed an ­altercation — he couldn’t see exactly what was happening — and yelled out his window, “Leave that girl alone!”

Moseley later testified that Mozer’s action “frightened” him, sending him back to his car. At this point, Genovese was still alive, her wounds nonfatal.

Fourteen-year-old Michael Hoffman, who lived in the same building as Mozer, also heard the commotion. He looked out his window and told his father, Samuel, what he saw. Samuel called the police, and after three or four minutes on hold, he reached a police dispatcher. He related that a woman “got beat up and was staggering around,” and gave them the location.

Other neighbors heard something as well, but it wasn’t always clear what. Some looked out the window to see Moseley scurrying away, or Genovese, having stood up, now walking slowly down the block, leaning against a building. From their vantage point, it wasn’t obvious that she was wounded. Others who looked didn’t see her at all, as Genovese walked around a corner, trying to make her way home at 82-70 Austin St.
