ELLENSBURG — A motorhome with a family inside went over an embankment on I-90 Monday afternoon near Ellensburg, killing a child and her grandmother, both from Snohomish County.
Kaci Edelbrock, 6, died at Kittitas Valley Healthcare in Ellensburg. Lois Edelbrock, 61, died at the scene. Both were from Snohomish, according to a memo from the Washington State Patrol.
In all, nine people were inside the vehicle, and all but one were hospitalized. They all lived in Snohomish or Monroe.
The driver, a 62-year-old man, lost control of the motorhome after one of its tires popped, trooper Brian Moore said.
“We do not believe there was any driver error, and this was a mechanical issue with the tire,” Moore said.
The man was taken by helicopter to Harborview Medical Center in Seattle, where he was listed in serious condition Tuesday morning, spokeswoman Susan Gregg said.
A Monroe woman, 41, and a 3-year-old boy also were taken to Harborview and were in satisfactory condition.
Helicopter crews flew two more boys, ages 6 and 13, to Virginia Mason Memorial Hospital in Yakima, according to the State Patrol.
“We are not commenting about these patients or even confirming they are here,” hospital spokeswoman Rebecca Teagarden said.
One of the children was in critical condition, Moore said.
Another boy, 15, was taken to Kittitas Valley Healthcare. He has since been released, spokeswoman Michele Wurl said.
The woman who died and the driver were grandparents to the kids, and the parents of the Monroe woman. It was unclear if the children were hers, Moore said.
The 40-foot motorhome was westbound on I-90 just outside Ellensburg when the crash occurred around 3:30 p.m. It was attached to a trailer carrying motorbikes. The vehicle went through a guardrail and over a bluff. It landed in Wilson Creek below.
An investigation is under way.
