Tonight, we're also learning more about that crash that left comedian Tracy Morgan in critical condition. This video taken by another car driving by just moments after the horrific crash. Tonight, we've learned of Morgan's injuries and what we're now hearing from Walmart, after the arrest of one of their drivers. ABC's gio Benitez on this again tonight. Reporter: Tracy Morgan's rep telling ABC news this afternoon the comedian is still in critical condition, but is more responsive. We're told he broke his leg, femur, nose and several ribs. This, after getting our first look at the man police charged with causing the accident that left the "30 rock" star and three others in critical condition. Morgan's long-time writing partner dying at the scene. Police sources say 35-year-old Kevin roper rammed this Walmart truck into Morgan's limo bus and later turned himself in. The driver of that limo remembering the moments right before the crash. I would say we were probably at about 5 to 6 miles an hour, just like steady coasting. Reporter: The New Jersey turnpike is known for other accidents like this. This stretch of I-95 is known as "The black dragon." It's straight and fast and police say one of the most dangerous roads in the northeast. Morgan and six others were on the way back to New York from a stand-up comedy show in Delaware. We're told the truck swerved to avoid the limo bus carrying Morgan, but instead, hit it. Morgan's limo lost control, spinning into two other cars and overturning. It felt like an explosion. I just remember the impact and the vehicle going by, seeing a little bit of the Walmart truck go by. We didn't know which way was up, which way was down. Reporter: Mogran's limo driver kicking the window through to get out. Then I climbed around and I heard Tracy screaming for help and I heard Jeff screaming for help. Reporter: Roper has now been charged with one count of death by auto and four counts of assault by auto. And we're told Morgan had surgery on his leg today, but David, he could be here for several weeks. All right, thank you, gio.
