CLIFFDELL--For the sixth time in the last week, a fatal car accident near Chinook Pass.
The latest: a Seatac man after his car went off the road and down a steep hill.
State troopers believe drugs or alcohol were involved in the crash that killed 20-year old Timothy Landry.
They also say he was going too fast on a gravel forest road off of State Route 410 when he lost control of his pickup truck, going off the road and down a steep enbankment.
As of Saturday night, 18-year-old passenger Desiree Lagerquist of Auburn was in serious condition at Yakima Regional Hospital.
This accident comes after five deaths last weekend: a triple fatality crash on Highway 12, and two fatal motorcycle accidents, one each on routes 12 and 410.
Troopers are sending out the warning: these roads wind, so be prepared.
"They're going too fast, too hard," Trooper Travis Lamb said. "It's just not worth it in the end."
Troopers also say nobody in the car was wearing a seatbelt.
After all these accidents, Washington State Patrol is doing emphasis patrols on Highways 12 and 410 to limit dangerous driving.
