King County prosecutors have charged an Issaquah man they say was drunk when he crashed into a rideshare van in September.
Charging papers say Douglas Burt Henderson was driving illegally in the carpool lane of Interstate 90 near Issaquah when he struck the back of a King County Metro Rideshare van. All seven people in the van were injured.
The 27-year-old faces two counts of vehicular assault.
The Seattle Times reports that the charges were filed three months after the Sept. 28 crash because prosecutors were waiting for medical reports.
