A woman died Wednesday afternoon when the car she was riding in was broad-sided and she was thrown from the vehicle, and a military commander was killed when he lost control of his motorcycle on I-80 outside Wendover.

Killed were:Patricia Blaser, Rexburg, Idaho.

Maj. James H. Spear, Peytonsburg, Ky.

The first accident happened at 2:30 p.m. at 400 South and Concord (1250 West) when the car that Blaser was riding in ran a stop sign. The car was broadsided by a van, and Blaser was ejected. She suffered massive head and neck injuries and was transported to LDS Hospital, where she was pronounced dead. Seventeen-year-old Ryan Colburn, also of Rexburg, suffered chest injuries and was listed Thursday morning in satisfactory condition at the hospital.

Two other people received minor injuries, police said.

In the other accident, Utah Highway Patrol Trooper Dan Bank-head said Spear was killed about 6:30 p.m. off I-80 29 miles east of Wendover after he lost control of his motorcycle.

Bankhead said he believes Spear grew tired before his Harley started to wobble and went off the side of the road. Spear then fought to regain control of the bicycle while traveling along the shoulder, but the bike slid sideways into a delineator pole.

At some point, Spear came off the bike and was found about 60 feet from the pole.

He was not wearing a helmet, Bankhead said, and was estimated to be traveling about 80 mph.

Spear, who was commander of the 366th Transportation Squadron at Mountain Home Air Force Base in Idaho, had been there since 1997 and in June assumed command of the 366th Transportation Squadron.
