Kin Yiu Cheung, 37, of New York, is charged with four felony counts of involuntary manslaughter in the May 31 crash. The accident left four people dead and dozens of other passengers injured.

Court records say Cheung fell asleep behind the wheel of the Sky Express bus en route from North Carolina to New York City.

Police said the bus hit an embankment and overturned about 30 miles north of Richmond, on Interstate 95.

Cheung’s trial was scheduled to begin in September, but was postponed until January. According to Caroline County Commonwealth’s Attorney Tony Spencer, the trial is now scheduled for March 7.

If convicted, Cheung faces up to 10 years in prison for each count. He has pleaded not guilty.
