Nine passengers died, and eight of the 38 people who were injured are still being treated in hospital.

On Monday, two Korean exchange students who survived the crash filed a civil lawsuit in a Tacoma, Wash., court.

The suit against Mi Joo Tour and Travel Ltd. claimed the bus driver was tired, speeding and ignored warnings of poor road conditions.
