A Colombian family and a Brooklyn school community are mourning after a building collapse killed a father, his nine-year-old daughter and their ten-year-old relative.

The three were among eight people who died when a three-story building on Flatbush Avenue collapsed on November 11. Police identified them as Juan Daniel Salvada Guzman, 31, Nicole Daniela Salvada Rodriguez, 9, and Kevin Santiago Reyes Gonzalez, 10, according to ABC News. Eighteen other people were injured.

For relatives overseas, the loss has shattered hopes of a reunion. Juan Carlos Zabala, a cousin living in Spain, told Gothamist that he had planned to visit the family in December, according to reporting reproduced by the New York Post.

He said the family had moved from Colombia to the United States roughly three or four years earlier, hoping to build a better future. The father worked for a cleaning company.

Zabala also described growing anxiety about immigration enforcement. According to his account, the parents increasingly limited their movements to work and home because they feared being stopped by federal immigration agents. He said the family was at home for Veterans Day when the collapse occurred.

The tragedy has also reached Kevin’s classmates at Success Academy Ditmas Park Middle School, where he was a fifth-grader. Just the previous week, he had joined classmates on a three-day trip to YMCA Camp Bernie in New Jersey.

Shari McKenzie, whose daughter attended Kevin’s class, told the New York Post that learning of his death left her devastated. Although she did not personally know his family, she organized an online fundraiser to help them. It had collected more than $3,500 at the time of that report.

McKenzie said her daughter was shocked and might only gradually understand the loss as Kevin’s absence from school became clear.

Meanwhile, investigators are examining the circumstances surrounding the collapse, including excavation work at the neighboring construction site. Questions have been raised about whether adequate measures were in place to protect the adjoining building.

The cause has not been established. Brooklyn District Attorney Eric Gonzalez said his office was investigating whether criminal conduct contributed to the disaster.
