Families of last victims in condo say waiting is agony

This undated photo provided by Dawn Falco shows Linda March, who is still missing in the collapse of a partial building in Surfside, outside Miami. Falco, said she and March had been talking on the phone until just two hours before the building crumbled. March rented Penthouse 4, in Champlain Towers South, the heartbreaking image now seen around the world with a set of bunk beds and an office chair still intact, yet precariously close to where the rest of the building was sheared off.
