SYRACUSE, N.Y. - The driver of a double-decker Megabus that smashed into a low bridge in upstate New York in September, killing four passengers, has been charged with criminally negligent homicide.

John Tomaszewski pleaded not guilty Monday. He made a wrong turn off a highway late at night near Syracuse, and the 13-foot-1-inch-tall (4-meter-tall) bus failed to clear the railroad bridge's 10-foot-9-inch (3.3-meter) span.

Those killed included Ashwani Mehta, 34, of India, and Benjamin Okorie, 35, of Malaysia.

The Philadelphia-to-Toronto bus was carrying 29 people, including the driver, when it crashed Sept. 11 on the Onondaga Lakeside Parkway in Salina.

After months of review, a grand jury decided to indict him on four counts of criminally negligent homicide plus one count of failing to obey a traffic control device.
