Survivor sues over Iowa building collapse, while search and rescue teams return home.

A resident of the Iowa apartment building that partially collapsed is suing the building’s owner and the city of Davenport for negligence, saying they knew about the dangers but failed to warn residents. The lawsuit claims that the owners tried painting over cracked exterior walls of the six-story building to hide the imminent threat. The catastrophe killed three residents. The suit does not include a specific amount of compensation sought.
