Motor home crash still puzzles investigators

DRAPER, Utah (AP) -- Investigators ruled out poor road and weather conditions but were left puzzled as to why a motor home crashed off an interstate bridge, killing six of the 10 people on board.
All 10 were thought to be members of a family from West Richland, Wash. Their names were not immediately released.
The driver, a man thought to be in his 40s, died on impact, spokesman Chris Kramer of the Utah Highway Patrol said today. The man's wife died later Sunday in a hospital. Also killed in the crash were two girls, ages 6 and 4, and two boys, ages 5 months and 7.
Three other children survived the crash. An 8-year-old boy was hospitalized in critical condition, and another 8-year-old and a 14-year-old had less serious injuries, Kramer said.
What happened
The motor home was traveling north on Interstate 15, about 20 miles south of Salt Lake City, when it went into the median and through a guardrail, then fell about 100 feet to a highway and rolled up an embankment.
Wind at first was thought a possible factor in pushing the 30-foot motor home from its left lane into the median, but with wind gusts no more than 19 mph Sunday, Trooper Anthony Carrubba of the Utah Highway Patrol discounted that.
"The road conditions were fine," Carrubba said. "There were no skid marks."
