Kin Yiu Cheung, 37, of New York, is charged with four felony counts of involuntary manslaughter in the May 31 crash. He was scheduled to go on trial next week. The trial has been rescheduled to Jan. 26, reports the Associated Press.

There were 58 people on board when the Sky Express bus en route from North Carolina to New York City swerved off Interstate 95, hit an embankment and overturned about 30 miles north of Richmond.

Four women--Karen Blyden-Decastro, 46, of Cambria Heights, N.Y.; Sie Giok Giang, 63, of Philadelphia; Josefa Torres, 78, of Jamaica, N.Y.; and Denny Estefany Martinez, 25, of Jersey City, N.J.--were killed.

The remaining 54 passengers were taken to area hospitals and treated for minor to severe injuries.

If convicted, Cheung, who suffered minor injuries, could face up to 10 years in prison for each felony manslaughter count, according to AP.

Police have said Cheung was fatigued at the time of the crash. Court records show he fell asleep at the wheel.
