Driver charged with manslaughter in Va. bus crash

Virginia authorities have charged the driver in this week's fatal bus crash with four counts of involuntary manslaughter.

The charges against 37-year-old Kin Yiu Cheung were filed after he appeared in the Caroline County Courthouse on a reckless driving charge. The charges stem from Tuesday's crash that killed four women and injured several other passengers.

Cheung had been out on bond, but was arrested Friday after the new charges were filed.

Police say Cheung was fatigued when the Sky Express bus swerved off Interstate 95, hit an embankment and flipped over about 30 miles north of Richmond. It had left Greensboro, N.C., on Monday night bound for New York City with 58 people.

Federal officials shut down the Charlotte, N.C.-based company after the crash for multiple safety violations.
