A 59-year-old Auburn man died Monday afternoon along Interstate 90 near Moses Lake in a head-on collision that also killed an 87-year-old Moses Lake man.

Robert J. Miller, of Auburn, and Emanuel Schaible each died at the scene in the 2:37 p.m. May 18 crash, according to the Washington State Patrol. Both drivers were alone in their vehicles.

Schaible reportedly drove the wrong way as he headed westbound in the eastbound lanes, according to the State Patrol press memo. Miller was traveling eastbound in the inside lane when he was struck. Schaible’s vehicle came to rest in the median and Miller’s on the right shoulder.

Miller, driving a 2014 Chevrolet Express van, wore a seat belt. Schaible, driving a 2005 Hyundai Santa Fe SUV, did not wear a seat belt. Both vehicles were totalled.

It is unknown if drugs or alcohol were involved, according to the State Patrol.
