The 9-year-old Issaquah girl reportedly seriously injured during the 15-car pile up on I-90 died Saturday from her injuries.

While several people were seriously injured in the Wednesday crash, the girl was the only person who died, according to the Washington State Patrol.

The wreck blocked westbound traffic for half of the day with traffic backed up to SR 900 in Issaquah.

WSP reports that a semi-truck driver lost control of his or her vehicle, and crashed into a log truck. The two trucks skid into several cars, stopping on the right hand shoulder.
