The bodies of two of the six wanted workers were recovered Wednesday from the icy waters of Baltimore Harbor. The bodies of four of their colleagues, all presumed dead, have not yet been found.

The victims, from Latin America according to the American press, were repairing potholes on the bridge when it collapsed into the Patapsco River. The US National Transportation Safety Board (NTSB) on Wednesday provided a detailed timeline of the tragedy, based on preliminary analysis of the container ship's data recorder.
