VICTORIA, Texas -- Federal investigators will spend the next week in the Victoria area trying to determine the cause of a deadly charter bus accident.
Wednesday's pre-dawn crash killed one passenger and injured dozens of others.
National Transportation Safety Board investigators will examine the vehicle, study the operating history and maintenance records and review the driver's record and logs.
The bus owned by Capricorn Bus Lines was heading back to Houston from Monterrey, Mexico, with 46 passengers on board when it rolled near Victoria.
Authorities are investigating whether driver fatigue was a factor.
Toxicology test results on him are pending.
Also, the Houston Chronicle reports Capricorn has been cited 19 times in the past three years for issues ranging from incomplete log books to cracked windshields and tire tread separation.
