West Valley resident Mailefihi Tuaone, 27, was killed when she was hit by a trailer being pulled by a semi-truck on I-15 Sunday night. Monte Keiaho, 25, Logan, was critically injured and remains in the hospital.

SALT LAKE CITY — A West Valley woman was killed and a Logan man seriously injured after they were hit by a semitrailer on I-15 Sunday night.

The driver of a Toyota Corolla heading north pulled over to the right side of the road to fix a flat tire about 11:50 p.m. just south of Davis County.

Monte Keiaho, 25, and Mailefihi Tuaone, 27, got out of the car to fix the tire and appeared to be completely in the emergency lane, according to a statement by Utah Highway Patrol Sgt. Jacob Cox.

At the same time, a semi was heading north in the right hand lane. A car in the next lane over prevented the driver of the semitrailer from moving out of the lane. A single trailer connected to the semitruck swung over and hit both the man and woman as it passed, according to police.

Tuaone died at the scene. Keiaho was critically injured and taken to Intermountain Medical Center. He was still in critical condition Monday but was expected to survive, Cox said.

Investigators are trying to determine whether the trailer strayed onto the shoulder or if Keiaho and Tuaone had moved onto the freeway, police said.

Police will not know if the driver of the semi, Las Vegas resident James Wiegand of Peace-Arch Trucking, will face charges until the investigation concludes. Currently there are no charges pending against the driver and he is cooperating with the investigation.

Utah Highway Patrol reminded those who have flat tires to move over as far away from the road as possible or to try and exit the freeway.
