From Roy to St. George, six people were killed in a series of traffic accidents that marked a deadly weekend on Utah's roadways.

"People think, 'It's not going to be me,'" said Utah Department of Public Safety spokeswoman Nicole Hunter. "It's that time of year — the first snowstorm, the first day of summer — when this happens."

The string of crashes started Saturday night in St. George. Kevin Barrick, 24, was killed instantly when he crossed several lanes of traffic in his Ford F150 pickup truck and collided head-on with another vehicle just after 7 p.m., according to the St. George Police Department.

Aston Pugmire, 78, also died as a result of that crash. Pugmire was taken to Dixie Regional Medical Center, where she later died. Her husband, Deward Pugmire, remained in serious condition in the hospital's intensive care unit Sunday, police said.

Other fatal accidents in Utah included:

• Jeffrey Spears, 52, was riding his motorcycle Saturday night in Roy when he was killed in a hit-and-run crash. A 24-year-old woman was being questioned in connection with the crash Sunday.

• A man involved in a high-speed chase with police died Sunday afternoon after crashing into an oncoming semitrailer truck in Parley's Canyon. The chase, which led police up and down the canyon, started as a suspected fraud, said Summit County sheriff's detective Josh Wall. No other information about the man was immediately released. No one else was seriously injured.

• Two children ages 7 and 10 died in a collision between a car and a truck in Provo Canyon early Sunday evening.

An Ogden mother and two of her young children also lost their lives in a weekend car crash in Colorado.

Maria Ruiz, 26, might have fallen asleep at the wheel as she drove through Colorado with her four children early Friday morning, police said. Ruiz overcorrected after her car drifted across the road near Pueblo, Colo.

Police said the vehicle crossed into oncoming traffic and was struck on the passenger side by a minivan. Ruiz and sons Juan M. Garcia, 8, and Joshua E. Ruiz, 7, were died at the scene. Two other children were being treated in a Denver hospital over the weekend.

As the summer travel season kicks off, Hunter said more people will be on the roads, and she cautioned drivers to use common sense during their travels.

"It's a good time of year for everyone to remember to slow down, definitely do not drink and drive, and beware of fatigued driving," she said.

Through April, there were 45 deaths as a result of traffic crashes, according to the Utah Department of Transportation.
