DAVENPORT, Iowa (AP) — The bodies of three men have been removed from the site of a collapsed six-story apartment building, the police chief in Davenport announced Monday.

Branden Colvin Sr.’s body was recovered Saturday. The body of Ryan Hitchcock was recovered Sunday and Daniel Prien early Monday. The discoveries came after authorities announced that the search for survivors had been completed, with attention turning to shoring up the remaining structure so recovery efforts could begin.

One of the residents injured in the collapse of an apartment building sued the city of Davenport and the building’s current and former owners on Monday, alleging they knew of the deteriorating conditions and failed to warn residents of the risk.

The complaint filed on behalf of Dayna Feuerbach alleges multiple counts of negligence and seeks unspecified damages. It also notes that additional lawsuits are likely.

Unresolved questions include why neither the owner nor city officials warned residents about potential danger. A structural engineer’s report issued days before the collapse indicated a wall of the century-old building was at imminent risk of crumbling.
