The owner of the charter bus that exploded while ferrying nursing home residents away from Hurricane Rita has a history of financial and safety woes, the Dallas Morning News reported Saturday.

The explosion Friday on Interstate 45 south of Dallas killed as many as 24 elderly passengers.

The newspaper said the owners of Global Limo Inc. filed for bankruptcy protection in February in a bid to block a takeover of the business for nonpayment of debt. The company's license also was revoked for a few days in May by federal authorities -- the second time since 1993.

The Federal Motor Carrier Safety Administration had singled out Global for full inspections when police stopped its buses, the newspaper reported. Global drivers have been ordered to stop driving five times after violations during the past 21/2 years, such as drivers not having logs that document how long they had been driving.

The tour company, based in Pharr, Tex., operates nine buses, according to records cited by the Morning News. It is owned by James H. "Butch" Maples, 64, and his wife, Kathleen, 46.

The newspaper could not reach Maples for comment. There was no answer late Friday at two listed phone numbers for Global called by the Associated Press.

The Houston Chronicle reported Saturday that the bus had lapsed registration but probably was pressed into service because of the hurricane. The Chronicle reported that the 1991 vehicle was not among the 10 buses registered with the state as being used commercially by Global.

"Because there's been a waiver under Hurricane Katrina and Rita, they don't have to provide [information on] every vehicle they use," Mark Cross, a spokesman for the Texas Department of Transportation, told the Chronicle.

Emergency crews investigate the scene where a bus caught fire and exploded, killing 24 people on Interstate 45 near Dallas.
