“The facts are continuing to unfold," CEO Bill Simon said. "If it’s determined that our truck caused the accident, Walmart will take full responsibility."
James McNair, a 62-year-old comedian from Peekskill, N.Y., known professionally as Jimmy Mack, was killed in the New Jersey Turnpike crash, authorities said Saturday. McNair also wrote for Morgan and was one of his closest friends.
According to a Robert Wood Johnson University Hospital spokesman, Morgan, 45, assistant Jeffrey Millea, 36, of Shelton, Conn., and comic Ardie Fuqua, 43, of Jersey City, N.J., remain in critical condition this morning (Sunday).
Another comedian, Harris Stanton, 37, of Brooklyn, N.Y., was treated and released from the hospital.
Truck driver Kevin Roper, 35, has been charged with one count of death by auto and four counts of assault by auto in the accident, the Middlesex County Prosecutor's Office said.
Roper, accompanied by his attorney, turned himself in to State Police on Saturday night, according to The Associated Press. He was processed and turned over to Middlesex County officials. Roper lives in Jonesboro, Ga.
Simon said he was "profoundly sorry" that a Wal-Mart Stores Inc. truck was involved in the accident, and the company said it is cooperating fully with law enforcement.
Simon pledged the company would "do what’s right for the family of the victim and the survivors in the days and weeks ahead.”
Morgan, Fuqua, Millea and Stanton were traveling from a gig at Dover Downs Casino in Delaware early Saturday when their 2012 Mercedes-Benz Sprinter van was struck by Roper's Wal-Mart truck on the New Jersey Turnpike, according to State Police.
Morgan's driver Tyrone Gale told ABC News that the impact felt like an explosion, after which the van felt like it flipped several times.
"I climbed around and heard Tracy screaming for help," Gale told ABC. "I climbed up on the body of the limo bus ... but I couldn't reach them."
Four other vehicles were involved in the crash, but none of their occupants was seriously injured. The National Transportation Safety Board is investigating the crash.
Morgan first gained prominence as a “Saturday Night Live” cast member. He went on to star in the critically acclaimed television series “30 Rock."
About McNair, Morgan's ex-wife, Sabina Morgan, told the New York Daily News: "He was one of the first comedians that took Tracy under his wing," she said. "They were very close."
Royale Watkins, a Los Angeles-based comedian who said he had performed in New York clubs with Morgan and McNair, described McNair as having a big personality.
"There may be guys like Tracy who get the fame and notoriety, but you have people like Jimmy Mack who have kind of energized and fueled cats like Tracy and kept them going on the road," Watkins said.
