A 90-year-old Wallula woman was killed Thursday when the car she was riding in hit the back of a semi-truck in Burbank.
Mildred A. Riley died at the scene of the accident at 9:22 a.m. on Highway 12 at Humorist Road.
Fog in the area may have contributed to the collision, but the Washington State Patrol is investigating.
Truck driver Jerman Pimentel, 31, of Quincy, was stopped at the traffic light at Humorist when Elmer Riley, 90, of Wallula, was driving west on the highway, the state patrol said.
The Rileys' 1991 Toyota Camry slammed into the back of the Kenworth truck hauling a cattle trailer, the state patrol said.
Elmer Riley was listed in critical condition Thursday night at Kadlec Regional Medical Center in Richland. Pimentel was not hurt. Both men were wearing seat belts. Mildred Riley was not, said the state patrol.
-- Also on Thursday morning, a multiple-car collision in Richland snarled commuter traffic on Interstate 182, closing the exit from Queensgate Drive onto the eastbound lanes of the highway.
Authorities said a car was attempting to merge onto the freeway from Queensgate when the motorist collided with anothercar.
A semi-truck then swerved to miss the cars and drove into the grassy median, causing other cars to collide.
No one was seriously hurt, said officials from the state patrol.
-- A 54-year-old Pasco man was hurt when he was hit by a car while crossing in a crosswalk at Road 32 and Court Street on Thursday morning.
A 2006 Mazda turning left into the crosswalk failed to yield at 9:30 a.m., said Pasco police.
The side-view mirror hit the man and knocked him to the ground, police said. He was not seriously injured.
The driver of the Mazda was cited for failing to yield to a pedestrian. His name was not released by police.
