Search resumes for missing in Florida condo collapse amid fears that rest of building could fall

Search and rescue efforts resumed Thursday evening at the Surfside condo collapse site after they were called off over fears that what's left of the building could cave in. Search crews made the decision to suspend the search early Thursday morning after discovering part of the building had shifted as much as a foot. 

Engineers detected a large column in the portion of the building that is still standing that had moved 6 to 12 inches. First responders scrambled out of the area after there were reports of cracking sounds.  "Our monitors went off where we are monitoring the cracks. We had three that signal that there was some expansion or whichever with those cracks," said Miami-Dade fire chief Alan Cominsky.
