3 men remain missing days after apartments collapsed. While families agonize, officials rethink demolition plans for the 'shifting' building

Two people who were previously unaccounted for after the partial collapse of an Iowa apartment building Sunday have been found safe, Davenport police said Thursday. But three others who lived in the crash zone remain missing.

Rescuers have been trying to find Branden Colvin Sr., Ryan Hitchcock and Daniel Prien, whose apartments were in the massive section of the building that disintegrated, police said.

Now, as families agonize and wait, city officials are grappling with how to proceed.

If rescuers try to re-enter, the rest of the building could topple and crush them.

"It's dangerous, and it's shifting," Mayor Mike Matson said Thursday.

But plans to demolish the Davenport building - originally scheduled for Tuesday morning - are now on hold.

"We're not anywhere near doing that right now," the mayor said. "We are working on a timeline. We are reaching out to experts that have particular expertise in taking it down (in) a dignified and respectful way."
