MATTAWA — A 35-year-old Mattawa man was arrested for DUI after a collision which severely injured a Sunnyside man, according to the Grant County Sheriff’s Office.

Law enforcement responded to a report of a collision at the intersection of Road R Southwest and Road 25 Southwest. Luis Garcia, 35, was allegedly driving a 2016 Kia Sorento east on Road 25 when he drove past a stop sign, colliding with 33-year-old Efrain Verdi-Rodriguez of Sunnyside, who was traveling north.
