(Hillsboro, OR)  --  The Washington County Sheriff's Office is coordinating a blood drive in honor of a deputy who was critically injured in a crash in April.  Doctors used 90 units of blood to save Deputy Mike Trotter's life.  That's nearly nine times the amount a blood in an average adult.  Trotter survived but faces a long recovery.  The Sheriff's Office has organized a blood drive in partnership with Bloodworks Northwest to help give back to others.  To schedule an appointment to donate, visit the Bloodworks Northwest website.
