Authorities say a New York woman is one of two people killed when a bus overturned on an Interstate 95 exit in Virginia.

Virginia State Police announced Wednesday that 81-year-old Janetta Cumberbatch of Jamaica, New York, was killed in the crash early Tuesday. Police say they're still trying to reach relatives of a man who was also killed.

State police say the Tao's Travel Inc. bus was traveling from Florida to New York with 57 people aboard when it entered the exit ramp. The bus ran off the left side and overturned. Police say investigators consider speed a factor. The surviving passengers' injuries ranged from minor to serious.

The bus driver, 40-year-old Yui Man Chow of Staten Island, New York, is charged with two counts of involuntary manslaughter.
