Three people were seriously injured in a three-car accident Saturday night on I-15 near Mills Junction in Juab County.

Injured were LeRoy Spriggs, 50, St. George; his wife, Carol, also 50; and their daughter, Danielle, 17.LeRoy Spriggs and Danielle were in stable condition Monday afternoon at Central Valley Medical Center, Nephi, and Carol Spriggs was listed as satisfactory at Utah Valley Regional Medical Center, Provo, where she may be released Tuesday.

Cory Jensen, 19, was taken by ambulance to Central Valley, where he was treated for minor injuries and released.

Uninjured in the accident were Gerald Gillins, 54, Pleasant Grove, and Angie Jensen, 19, Pleasant Grove.

Utah Highway Patrol Trooper Blair Bradford said the 9 p.m. accident occurred when Gillins attempted to tow a vehicle driven by Cory Jensen back onto the roadway from the median.

Gillins had hooked a tow chain onto the rear of the Jensen vehicle and was in the process of pulling it onto the northbound lane of the interstate when the vehicle driven by LeRoy Spriggs struck the front of the Jensen vehicle.

"It was almost a head-on accident," said Bradford. He said the Spriggs vehicle was traveling about 60 mph at the time of impact. The Jensen vehicle was traveling at approximately 6 mph.

Those in the Gillins vehicle were uninjured in the accident because of the long tow rope, Bradford said.

Both northbound lanes of the freeway, he said, had to be closed for 45 minutes until accident debris could be cleared.

A tractor-trailer unit was nearly involved in the accident but narrowly avoided the collision by swerving, said Bradford, adding that the Jensen vehicle did not have its headlights on.
