Tracy Morgan in critical condition as truck driver charged over crash

Morgan and two other men remained in critical condition in a New Brunswick hospital overnight.
Kevin Roper, 35, of Jonesboro, Georgia, is charged with one count of death by auto and four counts of assault by auto. Bail was set at $50,000.
Walmart president Bill Simon said in a Saturday statement a Walmart truck was involved and that the company "will take full responsibility" if authorities determine its truck caused the accident.
"We're praying for the family and friends of the passenger who lost his life in the terrible accident," the statement said.
The National Transportation Safety Board said it was working with state police on issues related to commercial trucking and limousine safety.
Saturday Night Live and 30 Rock star Morgan, comedian Ardie Fuqua Jr and another passenger, Jeffrey Millea, were flown to Robert Wood Johnson Hospital, where according to a spokesman they remained in critical condition. Another comedian, Harris Stanton, was treated at the scene and released.
The driver and occupant of the passenger seat of Morgan's vehicle were unhurt.
Police said the crash, which occurred at around 1am on Saturday morning on the New Jersey Turnpike, was caused when a tractor-trailer rammed into a limousine bus that was driving Morgan, McNair and two other men to New York from a concert in Delaware.
The tractor-trailer driver apparently failed to slow for traffic and swerved to avoid a crash, state police sergeant first class Greg Williams told reporters. The vehicle crashed into the back of the Mercedes limo bus, prompting a chain-reaction crash with a second tractor-trailer, an SUV and two cars.
Morgan's vehicle overturned, killing McNair.
Morgan's ex-wife, Sabina Morgan, told the New York Daily News McNair had been a mentor to the comedian, “one of the first that took Tracy under his wing”.
Morgan appeared on Saturday Night Live from 1996 to 2003, and on the hit NBC sitcom 30 Rock from 2006 to its close in 2013, receiving a 2009 Emmy nomination for best supporting actor.
