The FBI is conducting a court-authorized search of the vessel that crashed into a Baltimore bridge last month, according to FBI and Justice Department officials.

The Dali hit the Key Bridge on March 26, leading to the death of six construction workers who had been repairing pot holes in the overnight hours on the structure.
