The FBI has raided the container ship Dali, which caused the Francis Scott Key Bridge collapse, as part of a criminal investigation into the deadly incident. The investigation is running parallel to the National Transportation Safety Board's inquiry and is likely focused on determining if any federal laws were violated leading up to the disaster. The FBI's involvement suggests suspicion of criminal activity, potentially involving the ship's crew, companies, or other parties. Maryland officials have pledged to hold accountable anyone found responsible, and legal actions are being pursued against the ship's operators. The NTSB's preliminary report is expected in May, with the final report possibly taking up to two years.
