Two people were killed Friday and another pair Saturday in accidents on Utah roads.

DEAD:Maria M. Quadai, 31, Sacramento, Calif.

Aaron Spackman, 6, Richmond, Cache County.

Edward L. Stratton, 54, Valljeyo,

Calif.

Brian Jay Perry, 17, Tremonton, Box Elder County.

Quadai was killed and her three children injured when their car rolled on I-80 about 50 miles east of Wendover about 11:15 a.m., the Utah Highway Patrol said.

Quadai was dead at the scene, said UHP Trooper Kevin Mansor.

Her three children were flown by helicopter to Primary Children's Medical Center where all were listed in stable condition, a hospital spokesman said.

Adam Quadai, 1, and Aaron Quadai, 3, both suffered head injuries when they were ejected from the car, Mansor said.

Ayanna August, 8, suffered bruises and abrasions.

Witnesses said the eastbound Quadai vehicle drifted left, then overcorrected, causing it to roll once.

The Spackman child, a son of Mr. and Mrs. Dallas Spackman, was killed Friday when the three-wheel all-terrain vehicle in which he was riding rolled over backward, pinning him underneath.

The accident occurred in the street in front of the child's home in Richmond about 5 p.m.

Cache County Deputy Sheriff Dan Richards said the boy suffered severe head injuries and was dead on arrival at Logan Regional Hospital.

The third victim was killed Saturday when his vehicle ran off I-80, rolled and burned. Stratton was driving a 1970 Volkswagen bus east on I-80 near Castle Rock about 1:45 p.m. when the vehicle veered to the left, hit the median strip and rolled four times. The driver was ejected and the vehicle burned.

State Trooper Bill Judd said the accident is still under investigation. Perry was a passenger in a southbound car on I-15, 1 mile south of Honeyville, Box Elder County, when the vehicle drifted to the right. The driver, Amy Elizabeth Allen, 17, also of Tremonton, overcorrected and the car rolled twice in the median, the patrol said.

Perry was thrown from the vehicle, a dispatcher said, and died at 3:10 p.m. Saturday in McKay-Dee Hospital, Ogden. Allen and two other passengers, Tammie Christensen, 17, Tremonton, and Lynnette Thompson, 17, Snowville, were taken to Brigham City Community Hospital for injuries suffered in the 12:25 p.m. accident. Richard Pixton, 16, Tremonton, was treated and released, the UHP said.
