Shane Deal, of Pinedale, was gravely injured in the crash, Guenther said, which happened at about 3:15 p.m. Friday on Highway 191 just north of Granite Creek. A helicopter picked him up and headed for Eastern Idaho Regional Medical Center, but weather diverted them to St. John’s Health, where Deal succumbed to his injuries. He was 39.

Several troopers were in the area, Guenther said, and were dismayed that they couldn’t intercept the driver before someone was killed.

“You drink and you drive and this is what happens,” Guenther said. “It’s the typical sad cliche: Drinking and driving [don’t] go together, period.”

After buying a 1993 Ford F-250 truck with a snowplow in Idaho, Deal was driving the rig home to Pinedale, Guenther said, trailed by his sister, and Jewkes was northbound in a 2015 Jeep Cherokee Liberty. Her vehicle crossed into the southbound lane and struck Deal’s truck head-on.

Jewkes was treated for minor injuries at St. John’s Health, taken into custody by troopers and transported to the jail in Pinedale, where she is set to appear in a preliminary hearing Monday morning.

Deal worked for Ultra Energy in Pinedale, Guenther said.

A graveside service for Deal will be held at 2 p.m. Friday at Pinedale Cemetery, family members wrote on social media. A reception will follow.
