Undated (AP) _ Six people died in a wreck in Utah after another auto hit their car broadside, five died in a Texas collision, and three died in California when their van left the road and rolled over, authorities said.

Witnesses told police one of the the cars involved in the Magna, Utah, crash Sunday evening went through a red light at 80 to 100 mph before it struck the other car, said Sheriff's Lt. Dan Ipson. The adult male driver, a woman and five children in the car that was hit died, while a sixth youngster was critically injured.

The other driver suffered minor injuries, Ipson said.

The car containing the children was spun around at least four times and slammed into a utility pole and the children were thrown out of the car, he said. Several witnesses told deputies the other car had been passing traffic when it struck a curb and clipped off a sign before careening into the intersection.

Near Kirbyville, Texas, five people were killed Sunday and four others injured in a three-car accident on U.S. Highway 96, officials said.

One car collided head-on with a pickup truck, flew through the air and burst into flames when it crashed on top of another car. The dead were a couple and their two small children in one car and the driver of the pickup truck, police said.

In Los Banos, Calif., three people were killed and several others injured Sunday evening when a van returning crew members to San Diego after a college rowing competition drove off Interstate 5 and rolled over.

The California Highway Patrol in Merced said the accident occurred at about 8 p.m. three miles north of Santa Nella. The van was traveling southbound at a high rate of speed, police said.

One of the injured students, Troy Freeman, who said he was a member of the San Diego State University junior varsity crew team, said the van was headed home from the Pacific Coast Rowing Championships in Sacramento.

Freeman said the van was driving ''over the speed limit, but not faster than the other traffic,'' when it suffered a blowout in the right rear tire, went off the freeway and rolled over several times.

The Utah dead were identified as Diana Morrill, 32; her children, Bridgett Morrill, 10; Cherese Morrill, 8; Jack Morrill Jr., 6, and Sandy Morrill, 5. The driver of the car containing the children, a 32-year-old man from Magna, also was killed, but his name was not released pending notification of kin.

Brandy Morrill, 5, the twin sister to Sandy, was listed in critical condition at the Salt Lake City hospital after undergoing surgery last night.

Those killed in Texas dead were identified as Charles Hilton, 32, of San Augustine, the driver of the car that hit the pickup truck; his wife, Vickie Lynn, 31; their children, Sarah Ellen, 3, and Joseph Charles, 13 months; and Garrell White Jr., 23, of Vidor, the pickup's driver.

White's wife, Grace, 34, was in critical condition early today in Baptist Hospital at Beaumont, hospital spokeswoman Doris Bohler said, while their two daughters, ages 14 and 8, and the driver of the second car also were hospitalized.

The names of the dead in the California accident were withheld pending notification of relatives.
