OTHELLO - A horse had to be euthanized after a pickup truck and trailer hauling the animal landed on its top in a car wreck, six miles west of Othello, on Thursday morning.

The driver of the 2010 Dodge pickup truck, Jason A. Stewart, 35, Royal City, was heading eastbound on state Route 26 when a 2001 Chevrolet Malibu heading westbound allegedly collided with the truck, according to Washington State Patrol.

The car driven by Xu P. Huo, 29, Pullman, allegedly crossed the center line on SR 26 and turned sideways across both lanes when the truck collided with it, according to state patrol.
