Utah Highway Patrol Trooper Sgt. Blaine L. Robbins talks with members of the media as officials respond Friday, July 13, 2012 to a car accident on SR-201 in the west bound lanes at about 11900 west that took the lives of two adults a male and a female and sent a third adult to the hospital in critical condition. Investigators are still looking into what happened.

MAGNA — The Utah Highway Patrol was investigating Friday whether a motorist driving with a blown tire caused a collision that killed two people and left the driver in critical condition.

Witnesses told investigators they saw a passenger vehicle traveling east on state Route 201 near 12000 West at what appeared to be freeway speed about 10:30 a.m. Friday. But the vehicle was traveling with a blown tire that was shredding to the point where the left front tire was nearly on its rim, said Utah Highway Patrol Sgt. Blaine Robbins.

"But she continued on that tire, is what it looks like," he said.

The driver apparently lost control of her car or swerved into oncoming traffic. She continued traveling into oncoming traffic as the westbound and eastbound lanes became divided by a cement barricade.

After traveling about 100 yards on the wrong side of the road past the start or the barricade, the car clipped a gray pickup, Robbins said. The truck was able to pull off to the side of the road with little damage and no injuries to its occupant.

"Looks like the Fiesta was right behind that one and took the brunt of it," Robbins said.

A man and woman in their 30s in the Fiesta were pronounced dead at the scene. It took rescue crews 15 to 20 minutes to extricate the driver of the wrong-way vehicle before sending her by medical helicopter to a local hospital.

Names of the victims were not available pending notification of family members.

Robbins said investigators don't know why the driver traveled so far down the wrong side of the road without pulling over or just stopping.

"We don't believe alcohol was a factor, we don't believe it was a medical problem or anything like that was a factor. It's kind of a mystery right now. There's a lot to be looked at, a lot to be investigated, because we really don't know at this time," he said. "At this point there's a lot of unknowns."

Several other motorists stopped to lend assistance to the victims immediately after the collision.

"If you blow a tire, get yourself pulled over and get it fixed. We don't recommend driving on it," Robbins said.
