A toddler died following a three-car collision here Wednesday.

Killed was:Sadie Kozak, 4, Brigham City.

Kozak was riding unrestrained in the front seat of a car driven by her mother, Suzette Kozak, said policy Lt. Jess Palmer. Two front-seat air bags deployed at impact.

The child's 2-year-old brother received minor injuries, Palmer said. He was riding in a child safety seat in the back seat of the car but was not properly restrained.

No other injuries resulted, Palmer said.

The law requires children to be restrained either in a safety seat or seat belt, Palmer said. But research shows children and small adults are more safe restrained in the back seat of vehicles with air bags.

Air-bag deployment is blamed in several recent deaths of children. It is unknown if Sadie Kozak's death involved an air bag.

The collision occurred about 2:30 p.m. at 100 N. Main. Suzette Kozak, driving south on Main, allegedly ran a red light there, although an investigation continues, Palmer said. Citations are pending.

Three people riding in a minivan and the driver of another vehicle were unharmed, Palmer said.
