State police Capt. Eric Janis said Thursday that 19 people were treated at three Binghamton-area hospitals after the Wednesday night accident. He said police were trying to confirm that all the injured had been released.

They included a woman who was trapped underneath the bus and was dug out by emergency crews.

State Police Sgt. Todd Burdick told the Press and Sun-Bulletin of Binghamton that heavy rain and speed too fast for the conditions caused the accident.

The crash was on a rural stretch of Interstate 81 near Whitney Point, about 15 miles (24 kilometers) north of Binghamton. Burdick says the bus was traveling from Niagara Falls to Trenton, New Jersey.
