Six people, who were believed to be part of a road construction crew, are presumed dead after Baltimore’s Francis Scott Key Bridge collapsed early Tuesday morning. The collapse came after a 984-foot cargo ship hit the bridge’s pillar.

Maryland Gov. Wes Moore told reporters Tuesday evening it’s a “really heartbreaking conclusion to a challenging day.”

Late Tuesday, it was discovered that two of the construction workers who went missing after the bridge collapsed were from Guatemala, the country’s Ministry of Foreign Affairs said late Tuesday.

The victims: Eight people were on the bridge when it fell, according to officials. At least two people were rescued — one was taken to the hospital and was later discharged, fire official and the medical center said.

The incident: Video shows the moment the entire bridge structure falls into the water, as the ship hits one of the bridge’s pillars. CNN analysis shows that the ships lights flickered and it veered off course before it hit the bridge. Maryland Gov. Wes Moore said the crew on the ship were able to issue a “mayday” before colliding into the bridge, which allowed the authorities to stop incoming traffic from going onto the bridge.

Response efforts: Earlier, dive teams from various state and local agencies were brought in to assist in search-and-rescue operations, according to Maryland State Police Secretary Col. Roland L. Butler Jr.. The mission started with 50 personnel and continued to grow before the Coast Guard announced Tuesday evening that it was suspending its active search-and-rescue operation and transitioning to a “different phase.”

The investigation: Authorities are still working to establish exactly how the crash occurred. The National Transportation Safety Board will look into how the bridge was built and investigate the structure itself. It will “take time to dig through” whether the bridge had ever been flagged for any safety deficiencies, NTSB Chair Jennifer Homendy said.

Rebuilding the bridge: US Sen. Chris Van Hollen said the path to rebuilding the bridge will be “long and expensive.” Senior White House adviser Tom Perez told reporters Tuesday “it’s too early” to tell how long it will take to rebuild the bridge. President Joe Biden said Tuesday he wants the federal government to bear the full cost of rebuilding the collapsed bridge, noting that it will not wait for the company who owns the container ship DALI to shoulder the costs. Funding could come from the Federal Highway Administration as well as the Bipartisan Infrastructure Law, but it may require additional funding from Congress.
