UHP troopers investigate a fatal accident on I-215 near 4100 South in Salt Lake County Tuesday, May 27, 2014. The vehicle rolled several times.

TAYLORSVILLE — A Murray woman was killed Tuesday in a one-car rollover on I-215.

Kirsten Procter, 50, was the only person in the car when it overturned, according to the Utah Highway Patrol. Two dogs traveling with her were injured but not killed. Animal control took custody of the dogs.

Minor accidents had caused traffic to slow near 4100 South on northbound I-215 and were being cleared by tow trucks when Procter approached about 1:41 p.m.

"Traffic had just merely slowed down; it wasn't stopped, there were no travel lanes blocked," UHP Sgt. Stephen Manful said. "For whatever reason, we don't know why, she went off the road to the left, then back on across all traffic lanes."

Procter swerved to the left, overcorrected, and rolled at least four times before coming to a stop, he said.

"We are trying to determine if alcohol or drugs were a factor, if speed was a factor. We're still in the infancy of this investigation and we are looking at all possible angles," Manful said.
