The body of the last missing construction worker killed in the collapse of Baltimore’s Francis Scott Key Bridge in March has been recovered, officials announced Tuesday as demolition crews prepared to use explosives in the ongoing cleanup effort. Officials said the crew of the Dali will remain on board the grounded container ship while crews conduct a controlled demolition to break down the largest remaining span of the fallen bridge. The steel span landed on the ship’s bow after the Dali lost power and crashed into one of the bridge’s support columns on March 26.
