Shocking video showed the moment a massive cargo ship collided with Baltimore's Francis Scott Key Bridge early Tuesday morning, sending parts of the decades-old suspension bridge, along with people and vehicles, into the Patapsco River.
Six people who were on the bridge are missing and presumed dead, officials said late Tuesday. Two others were rescued from the water. All eight were construction workers who were repairing potholes on the bridge, officials said. There were 22 Indian nationals, including two pilots, aboard the cargo ship.
Investigators and officials are now crafting a timeline of events, including what caused the Singapore-owned vessel, called the Dali, to hit the bridge just minutes after leaving port. Here's what we know so far.

The entire staff of the federal government's Office of Infectious Disease and HIV/AIDS Policy is expected to be laid off, multiple federal health officials told CBS News Friday. The moves are part of a broader restructuring plan ordered by Health and Human Services Secretary Robert F. Kennedy Jr. that involves cutting 20,000 HHS positions.
