Injured along with Morgan were comedian Ardie Fuqua and Morgan's assistant Jeffrey Millea. The truck's driver, Kevin Roper, p leaded not guilty to criminal charges of vehicular homicide and assault. Last month, Morgan and his fellow crash survivors filed a lawsuit against Wal-Mart Stores Inc. in U.S. District Court in New Jersey, alleging that Roper had been awake for over 24 hours and in the midst of long shift that exceeded federal safety limits when the crash occurred — working conditions that Morelli says are the norm for Wal-Mart truckers. "I'm going to show if I have to in court that that's the culture (at Wal-Mart)," Morelli told Lauer. "That's what they set up. They know. ... They have to make sure that this doesn't happen." In response to the lawsuit — which seeks punitive and compensatory damages — Wal-Mart issued a statement that read, in part, "We are cooperating with the ongoing investigation and working to resolve all of the remaining issues as a result of the accident."
