Sentencing for the driver of a bus that crashed in Virginia killing four is scheduled for Wednesday.
Kin Yiu Cheung faces up to 40 years in prison after being convicted of four counts of involuntary manslaughter. Sentencing will be held in Caroline County Circuit Court in Bowling Green.
Cheung was convicted in November of charges stemming from the May 2011 crash on Interstate 95 about 30 miles north of Richmond. The bus was heading to New York from Greensboro, N.C.
Witnesses described Cheung's erratic driving before the bus swerved off the road, hit an embankment and overturned. They said at one point, Cheung stopped to buy four to five energy drinks and a cup of coffee.
According to testimony, 60 miles later, he fell into such a deep sleep, his head was parallel to the floor and when the passengers' screams didn't wake him, the bus tilting did. That's when they said Cheung overcorrected and the bus flipped.
A state trooper testified at the trial that Cheung nodded when asked whether he'd fallen asleep behind the wheel. Cheung's attorneys have called it a "horrendous accident."
We are will have full coverage of Cheung's sentencing set for Wednesday.
