A tour bus in northern California that already crashed once Sunday drifted off a freeway another time that same day, overturning and killing at least one person and injuring 30 others.

California Highway Patrol Officer Jeff Borgen told The Associated Press that the bus was traveling from Los Angeles to Pasco, Washington, when it drove off the road roughly 100 miles south of the Oregon border around 7:30 a.m. The bus rolled, eventually coming to a stop upside-down on a frontage road.

The identity of the passenger who was killed was not immediately released by authorities, but it was said he was a 33-year-old man from Parlier, California.

Two dozen other riders on the bus were taken to nearby hospitals. Most suffered minor injuries and were treated and released.

Three of the injured passengers were in critical condition, including one with severe head injuries who was flown to Marcy Medical Center in Mount Shasta via helicopter, hospital spokeswoman Joyce Zwanziger said. Most of the patients were taken to the same hospital's Redding location, including the people in serious condition.

About 50 miles earlier in the same trip, the bus struck a Denny's restaurant in Red Bluff, Borgen said. However, no injuries were reported in that crash. Red Bluff police, who investigated this incident, had no additional information Sunday night.

The bus was a 1996 Vanhool, being driven by 67-year-old Jose Victor Garcilazo of Los Angeles.

According to investigators, there is evidence in both crashes that driver fatigue may have been a factor. However, they did not say whether drugs or alcohol may have been involved or if charges were planned.

Yellow Arrow LLC, the bus' operator based out of Othello, Washington, has a current license and prior to Sunday had no reported accidents in the past two years, according to federal records.
