The Aguero family, on vacation from New Jersey, were staying on the 11th floor in a part of the building that did not collapse.
At least 159 people were unaccounted for Friday, a day after the collapse of part of a 12-story residential building in Surfside, Florida, authorities have said. Search and rescue teams have been feverishly scouring the site since shortly after 55 of the building's 136 units fell. Four people are dead, officials have said.
