Federal law enforcement authorities are investigating the events that preceded the collapse of the Francis Scott Key Bridge in Baltimore, according to two people familiar with the matter.
The FBI currently has agents on the Dali, the shipping vessel that collided with the bridge, a noted change in posture.
The investigation, which appears to be separate from the ongoing National Transportation Safety Board probe, is being conducted by Maryland's U.S. Attorney's Office and the FBI, entities that have had representatives at the crash site for weeks.
A spokesperson for the FBI said Monday in a statement, "FBI is present aboard the cargo ship Dali conducting court authorized law enforcement activity. There is no other public information available and we will have no further comment." A Justice Department spokesperson confirmed federal agents are aboard.
During a recent statement, the U.S. Attorney in Maryland, Erek Barron, announced, "My office typically does not confirm the existence of investigations or provide comments on them. However, it is important for the public to be aware that whether it involves gun violence, civil rights violations, financial fraud, or any other threat to public safety or property, we will hold those responsible accountable."
Legal representatives for the company that owns the Dali have not yet responded to inquiries from CBS News.
