Criminal Defense Attorney
Call a criminal Defense lawyer in Redmond, or search this site for one.
It will definitely make a huge difference if he hires an experienced DUI defense attorney in his state to handle this sticky situation for him. Use this website to find a few excellent candidates who devote most or all of their practice to DUI defense, then take the time to call a few (or have him call a few) to find the best fit. He should move quickly on this.
Hire an attorney and there are several here on avvo from your area. I live in Moses Lake WA and am quite a ways away so I assume you would hire someone from your area.
