The FBI and the National Transportation Safety Board are conducting separate investigations into the Francis Scott Key Bridge collapse in Maryland.

A criminal investigation by the FBI is focusing on adherence to federal laws and circumstances preceding the incident, including law enforcement activity on the cargo ship Dali.

Technical issues aboard the Dali, like alarms from refrigerated containers suggesting power inconsistencies, are under scrutiny.

Rescue operations are underway for at least seven missing individuals, with two people rescued and six confirmed fatalities, including the recovery of a fourth construction worker and a trapped victim in a construction vehicle.

Families of the victims are legally challenging a Singaporean company's attempt to limit its liability, while also launching their own investigation.

President Joe Biden has allocated $60 million in emergency funds for bridge reconstruction, complemented by Maryland legislation to secure full federal funding for the project.

The shipowner and manager are seeking to cap their liability at $43 million as the multifaceted investigation continues.
