Families in the Dominican Republic are mourning a tremendous loss.

At least 44 people have died and 146 are injured after the roof of the Jet Set nightclub in Santo Domingo collapsed during a Rubby Pérez performance in the early hours of April 8, Dominican authorities confirmed. 

“We are still working, searching for people in the rubble,” director of emergency management operations Juan Manuel Méndez said in Spanish during a press conference hours after the incident. “We presume that many of them are still alive. That’s why the authorities here with their teams will not stop until we find the last person in that rubble.”

Among those deceased were the saxophonist performing alongside Perez and Monte Crisiti governor Nelsy Cruz. Méndez shared that 146 people of the more than 300 inside the club at the time were rushed to the hospital. 

Perez’s daughter Zulinka Pérez told local outlets that her dad is in stable condition following the collapse, adding to Listin Diario that he started singing under the rubble so rescuers could hear him.
