Rescue teams burrowing beneath the rubble of a collapsed condo building in the oceanfront town of Surfside, Fla., detected sounds of banging on June 24, but no human voices, as an increasingly desperate search for survivors pressed into the evening.
At least one person was killed and 99 people are still missing, according to authorities. Also, it is uncertain how many were in the building when it came down.
Miami-Dade Fire Rescue assistant chief of operations Ray Jadallah said that the sonar sound devices being used in various areas inside the rubble have detected signs that could potentially be from some of those still missing.
“We did receive sounds, not necessarily people talking, but sounds,” Mr Jadallah said.
“What sounds like people banging, well not people but sounds of a possibility of a banging. Short of that we haven’t heard any voices coming from the pile.”
What caused the 40-year-old building to collapse remains unclear.
President Joe Biden has approved an emergency declaration for Florida, meaning the Federal Emergency Management Agency will help state agencies with the relief effort.
