SCHOHARIE, N.Y. (AP) -  Grief counseling and a vigil will be held following a devastating accident that killed 20 people in upstate New York.

The crash on Saturday in the town of Schoharie killed two pedestrians and 18 occupants of a limousine, including four sisters. The Times Union says the group of young adults heading for a birthday party all lived in nearby Amsterdam, New York, and grew up together. Two of the couples were newlyweds. The Amsterdam school district is offering grief counseling Monday.

One of the victims, Abby Jackson, was a teacher there. She and her husband Adam left behind two daughters: 4-year-old Archer and 16-month-old Elle. Democratic State Assemblyman Angelo Santabarbara says the vigil will be held on Monday evening in Amsterdam.
