A fifth victim injured in last week's tour bus collision in Seattle, Washington died Sunday.
A spokeswomen for Harborview Medical center identified her as a 20-year-old college student, but gave no other information.
The crash also killed a woman from Austria, an Indonesian man, a Japanese woman, and a 17-year-old Chinese girl. About 50 other passengers were injured, some seriously.
A team from the National Transportation Safety Board is investigating the crash in which a charter bus collided with a tourist vehicle called a Ride the Ducks bus on a major highway bridge.
Ride the Ducks buses are able to travel on land and in water. They have been involved in other fatal crashes including one that sank in the Delaware River in Philadelphia in 2010, killing two Hungarian students.
