A driver of a van full of children died Sunday in a Murray rollover, and a 17-year-old boy died earlier in the day after police say the car he was riding in was hit by a drunken driver in Ogden.

They were among 10 people killed in Utah crashes in four days.

Troopers believe the family in the van was on its way to church when the crash occurred.

The 35-year-old Midvale woman was the only one among the van's 10 occupants wearing a seat belt, according to the Utah Highway Patrol.

The Ogden crash, which happened just after midnight, left 17-year-old John Edwards dead and another 17-year-old boy in critical condition. Two other teens in the vehicle were injured after a large truck rear-ended their car, which was stopped at a light on 31st Street near the north onramp to I-15. The truck made no attempt to brake or swerve out of the way, said Ogden Police Lt. Scott Conley.

After the truck hit the car, leaving its trunk and rear seat crumpled into the front seat, it continued east, Conley said. Police said the 35-year-old driver, Daniel Rodriguez, then parked near 32nd Street and Grant Avenue and ran into a nearby house.

Later, police were given permission to enter the home, where they found and arrested Rodriguez on suspicion of leaving the scene of an injury accident and charges of automobile homicide and driving under the influence of alcohol. He is being held in the Weber County Jail.

Crashes in Wasatch County killed two late Saturday and wrecks in Iron County and Spanish Fork Canyon also claimed lives. A Huntsville family lost three of its members after a head-on crash in Layton on Thursday.

The driver in Sunday's rollover was identified as Delta Arellano Moreno. Six of the nine children in the van with her were ejected when it rolled.

A 15-year-old girl was taken to Primary Children's Medical Center in critical condition. Three others, ranging in age from 10 to 13, were taken to local hospitals in serious condition after the crash on I-15 near 6000 South. An infant and four other children were hospitalized in fair condition.

Their names will not be released, said Utah Highway Patrol trooper Randal Akers.

I-15 was shut down for about three hours Sunday afternoon to allow a medical helicopter to land and to allow crews to clean up after the accident.

A few minutes before midnight on Saturday, two Utah County residents died on State Route 189 near Wallsburg in Wasatch County after their SUV slid off the road, hit a signpost and rolled, police said.
