Brawner Builders' announcement came hours after Maryland Gov. Wes Moore insisted there was still hope that the six, who vanished after the Francis Scott Key Bridge disintegrated from the impact, might still be found alive.

A major Baltimore bridge collapsed like a house of cards early Tuesday morning after it was struck by a container ship, sending six people to their deaths in the dark waters below and shutting down one of the nation’s busiest ports.

Jeffrey Pritzker, executive vice president of Brawner Builders, confirmed that six were presumed dead and one survived during a telephone interview with NBC News. Their names were not released.

Pritzker's announcement came just hours after Maryland Gov. Wes Moore insisted there was still hope that the crew, who vanished after the Francis Scott Key Bridge disintegrated from the impact, might still be found alive despite having been in the freezing water for hours.

It was a crushing blow to the loved ones of the missing men, who had waited for hours at at a Royal Farms convenience store near the entrance of the bridge for word of their fate.
