The FBI has opened a criminal investigation into the collapse of the Francis Scott Key Bridge in Baltimore, focusing on the container ship Dali and whether its crew left the Port of Baltimore despite serious system problems. The probe aims to determine the events leading up to the ship losing power and colliding with the bridge support. This criminal investigation is separate from the National Transportation Safety Board's inquiry, with President Biden and Maryland Governor Wes Moore committing to holding responsible parties accountable. The White House has ruled out any nefarious action or terror in connection with the collapse, which resulted in six construction crew members' deaths.
