BALTIMORE (AP) — 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. Since then, the ship has been stuck amid the wreckage, and Baltimore’s busy port has been closed to most maritime traffic.

Six construction workers were killed in the collapse. The body of Jose Mynor Lopez, 37, was recovered Tuesday, officials said in a statement that evening. All the victims were Latino immigrants who were working an overnight shift filling potholes on the bridge. Police officers were able to stop traffic moments before the collapse, but they didn’t have enough time to alert the workers.
