The cargo ship Dali’s transformer was “jury-rigged” and had “cracked over time” and its backup transformer was unable to help because a safety feature had been “recklessly disabled,” contributing to the vessel ultimately knocking down the Francis Scott Key Bridge,

The Francis Scott Key Bridge collapsed in March, killing six road workers, after being struck by the Dali cargo ship which had lost power.

Federal prosecutors on Wednesday filed suit against the owner of the container ship that crashed into the Francis Scott Key Bridge in Baltimore earlier this year, alleging that the company and those on board the ship knew about persistent faulty electrical and mechanical problems and failed to fix them.
