"We did hear audible sounds, and they were searching for female voices. We heard [these voices] for several hours but eventually, we did not hear a voice anymore," Miami-Dade Fire Rescue Chief Alan Cominsky said at a briefing to the press.
Rescue operations have been underway at the collapse site since the building in the outskirts of Miami, Florida collapsed last week. The death toll currently stands at 18, with 147 residents being still unaccounted for. The US Department of Commerce's National Institute of Standards and Technology has launched a probe into the incident.
