SURFSIDE, Fla. (AP) – As more human remains emerge from the rubble of the collapsed Florida condo tower, the dead now include the first children. That announcement came Wednesday from the Miami-Dade mayor, who called the loss “too great to bear.” Authorities identified the children as 10-year-old Lucia Guara and 4-year-old Emma Guara. Their parents also perished in the collapse. Searchers found the remains of six people Wednesday, bringing the number of confirmed dead to 18. It was the highest one-day toll since the building fell nearly a week ago. The number of residents unaccounted for stands at 145.
