Families await news of missing in Surfside condo collapse: "I want to go back a day and change everything"

Rachel Spiegel just wants her mother, 65-year-old Judy Spiegel, home. "I want to go back a day and change everything," Rachel told CBS News' Manuel Bojorquez.

Judy was in the 12-story building, called Champlain Towers South, when it collapsed just after 1:30 a.m. local time on Thursday. She remains unaccounted for — one of 159 people who haven't been heard from since the collapse, officials said. "I guess we're just really thankful for all the hard work of the police, fire and EMS services that are out there continuing to search the rubble," her son Michael said.
