A woman who witnessed a multicar collision on a New Jersey highway that critically injured comedian Tracy Morgan and killed one of his associates called 911 to report a "terrible accident," according to audio recordings released on Tuesday.
"There's a terrible accident. The car flipped. It's on its side," the unidentified woman told an emergency operator moments after the early Saturday crash in which a Wal-Mart tractor trailer slammed into a limousine van carrying Morgan and several other people.
"There was an accident on the New Jersey Turnpike. It happened behind us," another caller said in 911 recordings released by the New Jersey State Police.
Morgan, 45, best known for his roles on "30 Rock" and "Saturday Night Live," and two other people riding in the van were critically injured and remained in a critical-care unit Tuesday, said a spokeswoman at the Robert Wood Johnson University Hospital Center in New Brunswick, New Jersey.
Comic James "Jimmy Mack" McNair, 62, a writing partner of Morgan's who was also in the van, died at the scene.
A fifth passenger was lightly hurt and released from the hospital.
Morgan's injuries included a broken leg, nose and ribs and he underwent surgery over the weekend, his spokesman Lewis Kay said in a statement Monday.
Kay dismissed online rumors that Morgan's leg had to be amputated.
"Rumors about amputating his leg are completely fabricated," the statement said.
The driver of the Wal-Mart truck, Kevin Roper, 35, has been charged with vehicular homicide and injury by auto for operating his commercial vehicle after not having slept for more than 24 hours, resulting in the fatal crash, according to prosecutors.
He is due to appear in Middlesex County Superior Court on Wednesday.
Wal-Mart said Tuesday that its 7,175 drivers meet some of the highest safety standards in the industry.
So-called drowsy driving, or driving with too little sleep, causes more than 100,000 crashes a year, resulting in 40,000 injuries and 1,550 deaths, according to the U.S. National Highway Traffic Safety Administration.
