The surveillance footage that captured the incident shows a man dressed in black pacing angrily outside his upstairs neighbor's apartment moments before a woman can be seen emerging from the apartment to hold a conversation with the man.
The surveillance footage obtained by the New York Post has no audio, so it is unknown exactly what was said during the conversation.
She is soon joined by a young man, who the police have identified as the woman's son, 27-year-old Chinwai Mode.
Moments into the conversation, Mode's stepdad, Bladimy Mathurin, can be seen walking out of his apartment with a pair of scissors in his hand and confronting his downstairs neighbor.
The situation escalates when the neighbor pulls out a handgun and points it at Mathurin, a 47-year-old school bus driver, who ignored the gun.
As soon as Mathurin turned and started walking back to his apartment, the neighbor shot him, and he immediately collapsed on the ground, according to the footage and police. The footage shows and police said that when the victim's stepson, Mode, tried to get away from, the neighbor allegedly fired multiple shots at him and fired at least two additional shots after the Mode had collapsed onto the ground already.
The neighbor then walked over to Mathurin, who was still struggling, and allegedly fired another shot at him, footage shows and police said. The New York Post reported that following the incident, the neighbor allegedly took the elevator, got out onto the street, and fled the scene.
The neighbor was identified as Jason Pass, 47, and on Nov. 1, he was shot and killed by police when he reportedly charged them with a knife during a traffic stop in Brooklyn, according to The New York Post.
The Post has learned via sources that nine .45-caliber shell casings and five bullet fragments have been recovered from the hallway. Police said that paramedics who responded to the scene found both Mathurin and his stepson dead from multiple gunshot wounds to the head and torso.
The woman seen in the footage was identified as Mathurin's wife and Mode's mother, Marie Delille, who said that her family has been involved in arguments over noise with the downstairs neighbor for years.
On Oct. 29, the night of the incident, the neighbor reportedly began banging on his ceiling over loud noise. Mathurin reportedly banged back, which prompted the neighbor to rush upstairs and kick on the family's front door.
"I was in the kitchen, doing dishes in the sink, I heard bang bang bang. I asked did anybody make noise? The kids be like, no mommy, nobody made noise. My husband banged back. The man came upstairs and kicked the door," Delille said in a statement to WCBS-TV, adding that the neighbor "hates us with every bone in his body."

The family also called him "psychotic," and added that the man would often complain about loud noises when the family was not actually making any.
Delille told WCBS: "My husband had no gun, no weapon. Why did you bring a gun to shoot my family? Why would you bring a gun to tear my family apart? Why? Why?"
Family friend Mickael Louis told WCBS about Mathurin, "He's a muscular guy. He looks intimidating, but that's not who he is. He is a wonderful guy."
