A dust storm swirling across I-15 between Nephi and Santaquin is believed to have been the cause of an 18-car accident at 4 p.m. Wednesday that killed one woman and injured several others.
In seperate accidents elsewhere in Utah on Wednesday an Illinois girl died after a semitrailer truck hit the sport utility vehicle in which she was riding near Cedar City and a bicyclist was killed in Salt Lake City.Killed were:
Pamela Parkinson, 30, Beaver.
Candice Kirkland, 11, Rock Island, Ill.
Alfred Billy, 38, of 682 E. 700 South in Salt Lake City.
-- Utah Highway Patrol Sgt. Paul Mangelson said Parkinson died at the scene of injuries incurred when the Chevy Tahoe she was driving struck the back of a tractor trailer.
A truck following Parkinson then smashed into her car. Police handling the accident shut down southbound I-15 for four hours.
Two boys riding in the car with Parkinson were taken to Mt. View Hospital in Payson. Sloan Parkinson, 6, and Skyler Ostler, 13, remain hospitalized Thursday morning in good and fair condition, respectively.
Amanda Williamson, 18, was riding in a Buick sedan that also smashed into the back of the tractor-trailer. She was taken by helicopter ambulance to Utah Valley Regional Medical Center with head injuries and was listed in critical condition.
Another passenger, Seth Jenks, 16, who was lying on the back seat of the Buick, suffered chest and pelvis injuries and was taken to Mt. View Hospital by ambulance where he was reported in good condition.
Witnesses said the dust blowing across the freeway severely hampered visibility for several miles. The loose topsoil was coming from a recently plowed farm.
In all, Trooper Greg Kelsey said, 14 southbound vehicles and four northbound vehicles were involved in the accidents.
Five other motorists involved in the accident were taken to hospitals in Payson and Nephi, where they were treated and released.
-- In the Cedar City accident, the driver of a semi fell asleep about 4:45 a.m. while traveling north in the slow lane of I-15 near Cedar City, according to the Utah Highway Patrol.
The truck rear-ended a sport utility vehicle, sending it rolling over into the median. The rollover ejected the 11-year-old girl, who died at the scene. She was not wearing a seat belt.
Of the other four occupants of the SUV, only one was not wearing a seat belt. Jonathan Kirkland, 13, suffered two broken legs when he was thrown from the vehicle. He is in fair condition at Valley View Medical Center.
Vivian Dale Laney, 40, Salt Lake City, was the driver of the semi. He was wearing a seat belt and was uninjured.
-- In the Salt Lake accident, a police report said Billy was riding against traffic in the outside southbound lane of Redwood Road at 9:40 a.m.
A delivery truck turned right from the east bound lane on 2100 South at Redwood, the report said. As the truck made the turn, the bike struck the side of the vehicle.
