Moment investigators board stranded Dali ship for the first time to get its black box and admit hazardous materials are seeping out after it hit Baltimore's Key Bridge: Comes as four of the six workers who died are named

National Transport Safety Bureau investigators are carrying out their work on board the stricken Dali container ship that's stuck in the Patapsco River, days after it hit the iconic Francis Scott Key Bridge. 

On Wednesday, rescuers in Baltimore recovered two more bodies in the search for the construction workers who were killed when the vessel collided with the bridge in the early hours of Tuesday, destroying it. 

Meanwhile, the Dali's 22 man crew are still on board the boat, with no date set for when they can disembark.  

An official said that divers located the bodies of Alejandro Hernandez Fuentes, 36, and Dorlian Ronial Castillo Cabrera, 26, inside of a red pickup truck that was plunged 25 feet into the frigid Patapsco River after the impact.

A day earlier, workers named two other victims as Miguel Luna, 49, and Maynor Suazo, 38. 

Their colleague, Jesus Campos, who was not working on the fateful night, earlier told the media that the group were on their meal break at the time of the crash and that two were in a work truck. 

Maryland State Police Superintendent Col. Roland L. Butler said while announcing the location of the bodies, that rescuers had 'exhausted all search efforts' as the debris has made the underwater crash site too volatile.

The giant vessel is made from thick, high-strength steel and is powered by one engine and one propeller. It's owned by the Singapore-based Grace Ocean and chartered by Denmark's Maersk.

NTSB Chair Jennifer Homendy was asked during the press conference about the supplies that the crew on the ship have. She joked: 'The cook was cooking when I got on board, it smelled very good, and I was very hungry.'  

Video released Wednesday showed NTSB investigators moving around the vessel, taking photos and surveying the wreckage left after Tuesday's disaster.  

The 22-man crew are all citizens of India. One suffered minor injuries after the collision. The ship was en route to Sri Lanka from Baltimore, a voyage that would have taken 27 days. 

The ship was carrying 56 containers filled with 764 tons of hazardous materials, including some flammable and corrosive items.  

More is being learned about the victims of the bridge collapse. 

Alejandro Fuentes lived in Baltimore, Dorlian Cabrera lived in Dundalk, Maryland. All of the members of the construction crew were from Latin America. They all worked for a company named Brawner Builders. 

'He was always so happy to be able to share what little he was able to make over there in the United States. Everyone else always came first,' Suazo's nephew, Hector Guardado, told the Washington Post. 

Soon after 1am on Tuesday morning, the Dali smashed into Baltimore's Francis Scott Key Bridge, destroying the structure entirely.

Miguel Luna's son, Marvin, said that he didn't know about the bridge collapse until his friends called him. 

Eighteen years ago, Sandoval set out on his own for the U.S. looking for opportunities. 

He had worked as an industrial technician in Honduras, repairing equipment in the large assembly plants, but the pay was too low to get ahead, one of his brothers, Martín Suazo Sandoval, said Wednesday while standing in the dirt street in front of the family's small hotel in Honduras.

'He always dreamed of having his own business,' he said.

Another brother, Carlos Suazo Sandoval, said Maynor hoped to retire one day back in Guatemala.

'He was the baby for all of us, the youngest. He was someone who was always happy, was always thinking about the future. 

He was a visionary,' he told The Associated Press by phone Wednesday from Dundalk, Maryland, near the site of the bridge collapse.

Maynor entered the United States illegally and settled in Maryland. At first, he did any work he could find, including construction and clearing brush. 

1.24 AM: In a suspected electrical failure, the lights on the ship flicker out and plunge the vessel into darkness. 

 Eventually, he started a package delivery business in the Baltimore-Washington area, Martín Suazo Sandoval said. 

Other siblings and relatives followed him north.

'He was the fundamental pillar, the bastion so that other members of the family could also travel there and later get visas and everything,' Martín Suazo Sandoval said. 'He was really the driving force so that most of the family could travel.'

Maynor has a wife and two children ages 17 and 5, he said. 

The COVID-19 pandemic forced Maynor to find other work, and he joined Brawner Builders, the company that was performing maintenance on the bridge when it collapsed.

Martín Suazo Sandoval said Maynor never talked about being scared of the work, despite the heights he worked at on the bridges. 

'He always told us that you had to triple your effort to get ahead,' Martín Suazo Sandoval said. 'He said it didn't matter what time or where the job was, you had to be where the work was.'

Things had been going well for him until the collapse. He was moving through the steps to get legal residency and planned to return to Honduras this year to complete the process, his brother said. 

Even though Maynor had not been able to return to Honduras, he had financially supported various nongovernmental social organizations in town, as well as the youth soccer league, his brother said. 

1.27 AM: A plume of thick black smoke billows from the top of the Dali as it careens towards the bridge.

Divers have now been force to suspend the search due to volatile conditions 

 The area depends largely upon agriculture — coffee, cattle, sugarcane — he said.

Maynor's employer broke the news of his disappearance to his family, leaving them devastated, especially his mother, who still lives in Azacualpa, Martín Suazo Sandoval said.

'These are difficult moments, and the only thing we can do is keep the faith,' he said, noting that his younger brother knew how to swim and could have ended up anywhere. 

If the worst outcome is confirmed, he said the family would work to return his body to Honduras.

In Mexico, President Andrés Manuel López Obrador said three Mexicans were on the bridge when it fell, including one who was injured but rescued and two who were still missing. He wouldn't share their names for the families' privacy.  

The tragedy illustrated the contributions that migrants make to the U.S. economy, López Obrador said.

'This demonstrates that migrants go out and do risky jobs at midnight. And for this reason, they do not deserve to be treated as they are by certain insensitive, irresponsible politicians in the United States,' he said.

Later, Col. Roland L. Butler Jr., superintendent of Maryland State Police, announced that the bodies of two men, ages 35 and 26, had been located by divers inside a red pickup submerged in about 25 feet of water near the bridge's middle span.

One was Guatemalan Dorlian Ronial Castillo Cabrera, 26, and the other 35-year-old Alejandro Hernández Fuentes, originally from Mexico.

Guatemala's Foreign Affairs Ministry had earlier confirmed that two of its citizens were among the missing. And El Salvador's foreign minister, Alexandra Hill Tinoco, posted Wednesday on X that one Salvadoran citizen, Miguel Luna, was among the missing workers.

Federal and state investigators have said the crash appears to have been an accident.
