BOWLING GREEN, Va. (AP) -- Prosecutors have rested their case in the trial of the driver in a fatal Virginia bus crash that killed four passengers and injured dozens more.
Kin Yiu Cheung is charged with four felony counts of involuntary manslaughter stemming from the May 2011 crash on Interstate 95 about 30 miles north of Richmond.
Caroline County prosecutors called 15 witnesses Thursday, including several passengers on the low-fare Sky Express bus from Greensboro, N.C., to New York.
They described erratic driving, including weaving and repeatedly speeding up and slowing down, before the bus swerved off the road, hit an embankment and overturned.
A state trooper also testified that Cheung nodded when asked whether he'd fallen asleep behind the wheel.
Cheung faces up to 10 years in prison for each count if convicted.
