LAS VEGAS (AP) - A federal official says the driver of a tour bus that crashed near Hoover Dam, killing seven, was distracted by a problem with his door minutes before the he lost control.
National Transportation Safety Board investigator Peter Kotowski told reporters on Saturday that the first stage of the probe has turned up no mechanical problems with the bus.
A tour guide and six Chinese tourists were killed in the Jan. 30 crash along U.S. 93 in Arizona, 26 miles south of the Nevada border. Ten others were injured.
Kotowski says the driver, 48-year-old Han Dong of Rosemead, Calif., was properly licensed.
He says investigators have not found anything wrong with the driver-side door of the bus, which witnesses said was briefly open before the crash.
