Six Utahns died over the Labor Day weekend, and another man was killed Tuesday morning in separate one-vehicle traffic accidents.

Dead:Kent L. Daniels, 29, West Valley City.

Young S. Seo, 31, Salt Lake City.

Ruby Willis, 80, Helper.

Roberta H. Standish, 40, Salt Lake City.

Robert Elio Cuch, 26, Whiterocks, Uintah County.

John Johnson, 24, address unavailable.

Leon C. Kinder, 41, 265 Garden Ave., South Salt Lake.

Daniels was riding a motorcycle east on I-80 near the I-215 interchange and attempted to pass a semitrailer truck in the emergency lane on the right side of the road, said Utah Highway Patrol dispatcher Tad Vawdrey. He apparently hit the side of the truck driven by Billy Scott Harris, 39, of Sonora, Texas. Daniels was pronounced dead at the scene Monday night, Vawdrey said. Harris was not injured.

Seo was killed when a car, driven by her husband, Kgung W. Seo, 31, rolled at 1:48 p.m. Monday on I-15, 19 miles south of Beaver. Their 4-month-old son Eric was flown to Primary Children's Medical Center and was in serious condition Tuesday morning.

A dispatcher said when the car rolled, the baby was ejected and flew 75 feet into the air and slid for another 25 feet. Five-year-old Siean Seo and Kgung Seo were in good condition Monday night.

Vawdrey said Cuch was driving a vehicle near the U-121 and Whiterocks junction near Vernal when his vehicle went off the side of the road and hit a tree. The vehicle rolled once and ejected Cuch Saturday night.

Standish died Sunday from injuries suffered in a Saturday morning accident. She was traveling south on I-15 in Utah County when her car left the road and rolled in the median, the Highway Patrol said.

She was taken to Mountain View Hospital in Payson, where she died Sunday.

UHP authorities said Willis' body was discovered Sunday in her vehicle at the bottom of a dry wash on Old Coal Creek Road north of Wellington in Carbon County.

Apparently, the accident occurred Saturday night when the vehicle left the road and crashed into the wash, according to the UHP.

Johnson died Monday after suffering head injuries from a freak fall out of the back of a moving truck, according to Payson police reports. The accident took place at Sixth S. and Third East.

Johnson was sitting on a tool box in the bed of the truck westbound on Sixth South. The truck turned onto Third East causing the man to slide off the tool box, out of the truck and on to the ground.

He was pronounced dead on arrival at Mountain View Hospital following the accident.

The highway patrol reported that Michael Carling, 28, Bountiful, died Wednesday night when he lost control of his vehicle and veered off the highway down an embankment. Vawdrey said Carling was driving above Bountiful on Canyon Road and Skyline Drive when the accident occurred. His vehicle was found 600 yards from the road and his body was found 100 yards beyond that.

Kinder was killed in a hit-and-run accident Tuesday morning in the intersection of 13th South and 56th West. He was walking near the intersection of 13th South and 56th West, apparently after his car had broken down one-half mile east, said Salt Lake Police Detective Kent Whitehead.

A motorist northbound on 56th West skidded into the intersection, hit the man then turned around and fled, police said. Another motorist saw the man's body at the side of the road about 6:10 a.m. then drove several miles to a phone and called police, Whitehead said.

Kinder, married and a father of three children, was dead at the scene.

Police had found no witnesses to the accident Tuesday morning. Anyone who was driving in the area and may have seen something that would help with the investigation, or who may have seen a vehicle with suspicious front-end damage, is encouraged to call the police, he said.
