At least 19 people remained hospitalized Thursday, a day after a bus carrying nearly 50 people from Mexico to Houston crashed, killing one.

Fifteen people were in two Victoria hospitals, including one passenger who had to have an arm amputated. All were reported to be in fairly good condition.

One person was transferred to a Houston-area hospital to be closer to family, and a second patient was likely to be moved from Victoria to Houston, said Shannon Spree, a spokeswoman for Citizens Medical Center in Victoria.

At least three people remained hospitalized in San Antonio after being sent there after the crash. All were reported to be in stable condition.

A call to another San Antonio hospital where a patient was hospitalized after the crash was not immediately returned Thursday.

The bus, owned by Houston-based Capricorn Bus Lines Inc., was traveling from Monterrey, Mexico, to Houston when it overturned on U.S. 59 near Victoria about 4:15 a.m. Wednesday. Department of Public Safety officials said the driver apparently overcorrected after the bus veered off the road, causing it to land on its side. A small pickup truck then rammed the bus, but the driver of the truck was uninjured.

Tom Vinger, a DPS spokesman, said the crash investigation continued and that a report on the accident would be released within 10 working days.

Vinger said Wednesday that driver fatigue was one of the factors in the investigation, including how long the driver was behind the wheel and whether state or federal restrictions on driving hours were violated.

The bus company identified the driver as 42-year-old Roberto Cruz. He wasn't seriously injured, and Vinger said Thursday he had not been charged with anything.

Pete Kotowski, a National Transportation Safety Board investigator in charge, said the agency is conducting its probe in conjunction with DPS and that investigators were brought to Victoria to help.
