Morgan, 45, was travelling in a limo bus when the crash happened. Another passenger, comedian James McNair, was killed. Their vehicle was struck by a Walmart truck, whose driver has since been charged with death by auto, as well as four counts of assault by auto. Police said Kevin Roper, 35, apparently failed to slow for traffic and swerved at the last minute to avoid the crash. Instead, his truck hit the back of the limo bus. 

The driver of Morgan's vehicle, Tyrone Gale, said he could hear passengers in distress after his vehicle flipped over.

"I climbed around and heard Tracy screaming for help," he told ABC News.

"I climbed up on the body of the limo bus . but I couldn't reach them."
