Sleeping bus driver Kin Yiu Cheung charged with involuntary manslaughter

The Queens man who was asleep at the wheel when a budget motor coach crashed in Virginia was charged Friday with four counts of involuntary manslaughter.

Kin Yiu Cheung, 37, of Flushing, who had been out on bail on a reckless driving charge, was immediately jailed.

"It's never easy to make determinations to bring serious charges, but there was enough evidence to bring the charge," Caroline County prosecutor Anthony Spencer said after Cheung's arrest.

Cheung's lawyer, Murray Janus, called the wreck that also left dozens of passengers injured a "tragic accident."

Police said Cheung was exhausted when the Chinatown-bound Sky Express bus he was driving swerved off Interstate 95 early Tuesday, hit an embankment - and flipped over north of Richmond, Va.

Cheung was the only person on the bus who was wearing a seat belt - and the only person who wasn't hurt.

Among the dead were two women from Queens - Josefa Torres, 78, of Jamaica, and Karen Blyden-Decastro, 46, of Cambria Heights.

In the wake of the accident, the feds shut down the North Carolina-based bus company for multiple safety violations.

It had been running three daily buses from lower Manhattan to Charlotte, N.C.
