Finding bones from a centuries-old skeleton beneath a historic tree sounds like a segment out of a scary movie, but the scene became all too real when a Connecticut woman made the frightening discovery the day before Halloween.

On Tuesday, Katie Carbo, a bystander, alerted police about a skeleton found beneath a historic oak tree that toppled over from Hurricane Sandy's intense winds, the New Haven Independent reports. Carbo spotted the skull in the roots of the fallen oak. The skull was positioned upside down with its mouth open, still connected to the spine and rib cage. Investigators headed to the scene at the New Haven Green, a 16-acre park that had once been used as a burial ground.
