SCHOHARIE, N.Y. (AP) — A limousine carrying four sisters, other relatives and friends to a birthday celebration blew through a stop sign and slammed into a parked SUV outside a store in upstate New York, killing all 18 people in the limo and two pedestrians, officials and victims' relatives said Sunday.
The weekend crash was characterized by authorities as the deadliest U.S. transportation accident in nearly a decade. The crash turned a relaxed Saturday afternoon to horror at a rural spot popular with tourists viewing the region's fall foliage. Relatives said the limousine was carrying the sisters and their friends to a 30th birthday celebration for the youngest.
