Rescuers recovered the bodies of two construction workers trapped within a red pickup truck and submerged 25 feet below the Patapsco River after a container ship crashed into Baltimore's Francis Scott Key Bridge.

The two deceased workers were identified as Dorlian Ronial Castillo Cabrera, 26, and Alejandro Hernandez-Fuentes, 35, according to authorities.

The search for the remains of an additional four construction workers - originally from Mexico, Honduras, El Salvador and Guatemala - and presumed dead following Tuesday's tragedy continued into Wednesday evening as government officials provided an update on their latest recovery efforts.

Maryland Gov. Wes Moore said there was no definitive timeline to the investigation.

"The thing that I do know is that the task in front of us - it will be real. It will be daunting," Moore told reporters.

"But despite this task ahead of us being daunting, I can tell you right now, our resolve is unshaken. We will get to completion. We will do it together," Moore promised.

He added, "This work will take time, but we're going to make sure that we are going to leave no one behind."

Investigators with the National Transportation Safety Board were able to retrieve the ship's black box Wednesday morning. They hope it will help them piece together the final moments before the Dali slammed into the bridge.

Officials said they were aware the ship encountered power challenges and lacked the ability to steer before the deadly crash. An indefinite pause has been placed on the passage of ships in and out of Baltimore.

"The President has directed us to move heaven and earth," Tom Perez, Senior Advisor to President Joe Biden, said. "Those are not my words. Those are his words-to make sure we are helping the remarkable people of the great state of Maryland move forward."

One person hospitalized during the crash was released on Wednesday.

The investigation continues.
