Live Updates: Florida building collapse search continues as 159 still unaccounted for

Around-the-clock search efforts are continuing Saturday morning at the site of a collapsed apartment building in Surfside, Florida. At least four people are dead and 159 are still unaccounted for a little more than two days after the condo tower came crashing down while people inside were sleeping.

Crews searched through the rubble overnight in hopes of finding any survivors. "All of our training tells us that for at least the first 72 hours there is a high likelihood of people that could be alive in there," said Miami-Dade Fire Rescue division chief Danny Cardeso.
