'The Bridge Is Down': Hear The Dispatch Audio From Key Bridge Collapse

BALTIMORE, MD — As Maryland Transportation Authority officers raced to hold traffic from driving onto the doomed Key Bridge, they ran out of time to reach a road crew patching potholes in the middle of the span.

"The whole bridge just fell down," an MDTA worker calls into the conversation. "Start ... start whoever, everybody, the whole bridge collapsed."

A dispatcher then asks if officers know whether everyone had made it off the bridge.

Officials said the six construction workers missing in Tuesday’s disaster were originally from Guatemala, Mexico, El Salvador and Honduras. Authorities said the men are presumed dead after the cargo ship Dali lost power and crashed into the Key Bridge.

Crews returned Wednesday morning to search for the bodies.

Two construction workers were rescued from the water early Tuesday. One went to Maryland Shock Trauma, and the other refused treatment.

Guatemala’s Ministry of Foreign Affairs confirmed Tuesday evening that two of the missing workers are originally from Guatemala. They are 26- and 35-year-olds originally from San Luis, Petén and Camotán, Chiquimula. Guatemalan officials said they called the brothers of both presumed victims and are trying to meet with the families.

The Mexican Embassy to the U.S. said later in the evening that one of the workers is originally from Mexico.

Guatemala and Mexico both confirmed that another victim was originally from El Salvador. Guatemala said at least one more missing person is from Honduras.

Authorities have not yet confirmed the names of any of the victims. As of Wednesday afternoon, none of the bodies have been found by divers searching through the bridge wreckage in the Patapsco River.

“We’re talking about frigid temperatures, we’re talking about a moving tide, we’re talking about darkness and mangled metal, that’s still very much in the middle of this water,” Gov. Wes Moore said on CBS News. “The heroism of our first responders was just outstanding.”

CASA, an immigrant rights advocacy group, said Miguel Luna, originally from El Salvador, never returned home from working on the bridge.
