Driver Of Fatal Bus Crash That Killed 15 To Go On Trial
The driver of a tour bus that crashed on I-95 killing more than a dozen people is scheduled to be tried on manslaughter charges beginning Thursday.

The crash was horrific and cost 15 people their lives when the World Wide Travel bus slammed into a guardrail,on March 12, 2011, tipped over on its side, slid across the roadway and had it's roof sheared off.

The driver, Ophadell Williams pleaded not guilty to manslaughter and criminally negligent homicide charges after prosecutors said he was seriously sleep deprived but drove anyway. Some said he fell asleep at the wheel.

The accident happened just before day break as the bus was returning to Chinatown from a trip to the Mohegan Sun Casino in Uncasville, Conn.

The driver said a truck cut him off causing the accident. But investigators were not able to verify his story. Williams attorneys say he was alert and awake at the time of the accident and committed no crimes.

In June, the National Transportation safety board did not conclude the driver fell asleep but did say driver fatigue and a bus company that provided too little safety oversight contributed to the tragedy.

The bus was traveling 78 miles an hour in a 50 mph zone when it crashed, fell over and slid into a pole supporting a highway sign that sheared off the top. If the driver is found guilty he could face time in jail.
