More than 80 Miami-Dade Fire Rescue units and technical rescue teams responded to the scene of the condo collapse.

The 12-story condo building has 136 units, and officials say 55 units on the northeast side were involved in the collapse.

Firefighters used truck-mounted ladders to reach people trapped on balconies. They also did a floor-by-floor search to evacuate the building. At one point they were pulled out because of concerns over the building’s structural integrity and falling debris.

Miami-Dade Fire Rescue reported that 37 people have been rescued. Of those rescued, 35 were pulled from the still standing building and two from the rubble, including a 12-year-old boy.

Rescue crews are doing DNA tests with family members to identify victims.

According to Miami-Dade Mayor Daniella Levine Cava, 102 people are accounted for at this time.

A man who lives in a building next door said he felt it.

“The building shook and then I looked out the window and you couldn’t see, I thought it was like a storm or something coming in. When the dust cleared, the back two-thirds of the building was gone, it was down to the ground,” he said.
