Harrowing new footage from an in-home surveillance camera captured the moment a Brooklyn apartment building crumpled to the ground, killing eight people and injuring 18 more. The video, exclusively obtained by Gothamist and CBS News, was taken inside the third-floor apartment at 1321 Flatbush Avenue of resident Anderson Velez, who lives there with his wife and two young children, seconds before the building collapsed into an active construction site next door.

In the six-second clip, Velez's 9-year-old son can be seen retrieving a gallon of milk from the fridge while his 2-year-old plays on the floor. Velez's wife then opens a door to the living room, screaming frantically, prompting the older boy to run toward his mother, away from the wall before it dramatically crumbles. Velez told the local publication in Spanish that the movement "saved his life." The toddler was swept up in the rubble when the wall caved in, but was pulled out with only scrapes to his forehead and legs, his body covered in dirt.S2

Velez, who was in the Bronx for work at the time, said he received a frantic call from his wife as she begged rescue workers to pull their two sons from the debris. He said his wife suffered serious injuries to her ribs, spine and collarbone, and that his 9-year-old remains in the ICU after surgery. "I am still in shock," he told Gothamist. "The truth is, I'm trying to be strong for my son, but I feel terrible."S2

Velez said the family had only just moved into the building earlier this month after living in a homeless shelter. He and his family are now being housed at a Brooklyn hotel the city is offering to people displaced by the tragedy.S2
