NTSB looking at role of commute in Morgan crash

(AP) -- Accident investigators are looking into what role the commute of the driver charged in the accident that injured comedian Tracy Morgan played in the fatal crash.
NTSB spokeswoman Kelly Nantel says that Wal-Mart driver Kevin Roper lived in Georgia, but his job was based in Delaware.
A criminal complaint alleges Roper hadn't slept for more than 24 hours before the accident. Wal-Mart has not explained what Roper's driving route was.
Roper pleaded not guilty Wednesday to charges of death by auto and assault by auto stemming from the crash early Saturday morning.
The 35-year-old was driving a Wal-Mart truck when he allegedly swerved to avoid slowed traffic and plowed into Morgan's limo. Morgan and two others are in critical but stable condition.
