Updated:BOWLING GREEN, Va.,None - A grand jury has certified four felony charges against the driver of a bus that crashed in Virginia, killing four passengers and injuring dozens more.
The Caroline County grand jury certified the involuntary manslaughter counts against 37-year-old Kin Yiu Cheung of New York on Wednesday.
Court records show Cheung admitted to police that he fell asleep at the wheel when the Sky Express bus bound for New York swerved off Interstate 95 about 30 miles north of Richmond, hit an embankment and overturned with 60 people aboard.
A document obtained by The Associated Press shows Cheung's attorneys are asking a judge to suppress any statements he made because he allegedly was denied access to counsel and was not advised of his Miranda rights.
