EDISON - Actor Tracy Morgan remains in intensive care at Robert Wood Johnson University Hospital in New Brunswick following a deadly six-car crash on the New Jersey Turnpike, and a truck driver is now facing charges in the crash.

The accident happened on the northbound side of the turnpike in Cranbury Township between exits 7A and 8A, just south of the Molly Pitcher Service Area, at around 1 a.m. Saturday.

Police say one person was killed. Morgan and several others were injured in the crash that also involved two tractor-trailers. Morgan was a passenger inside a limousine bus that overturned. Among those traveling with him were fellow comedians Ardie Fuqua Jr. and Harris Stanton.

Based on what police have said, a Wal-Mart tractor-trailer hit the bus, causing it to flip over.

Prosecutors have announced that a truck driver from Georgia is charged with death by auto in the crash. Middlesex County prosecutors said 35-year-old driver Kevin Roper also faces four counts of assault by auto stemming from the crash.

Morgan's publicist, Lewis Kay, released a statement saying Morgan's family doesn't expect his condition to change Saturday. The other person in critical condition is a man named Jeffrey Millea. He and Morgan were air lifted to the hospital.

Comedian James McNair, of Peekskill, New York, has been identified as the limo bus passenger who died in the crash, officials said. McNair, who went by the nickname Jimmy Mack, was a close friend of Morgan's.

Investigators had shut down the surrounding area for about five hours until the scene was cleared.

The CEO of Wal-Mart released a statement saying his thoughts are with everyone involved, and that his company is cooperating with law enforcement. Meanwhile, the National Transportation Safety Board is joining the investigation.
