Sonar Images Reveal Mangled Francis Scott Key Bridge Submerged in Baltimore's Patapsco River

New sonar images show the mangled remains of the Francis Scott Key Bridge lying at the bottom of the Patapsco River in Baltimore. After collapsing into the river, the bridge appears unrecognizable in the 3D renderings. The images, taken using a sonar tool from the US Navy, will help divers navigate the challenging recovery operation amid limited visibility. Crews are working to remove debris where four victims are believed to still be trapped. Two bodies have already been recovered from under debris in the river.
