The bones were picked clean, weather-beaten, and so small that the boy who found them on April 14, 1922, thought they were the remains of a large dog. Later, the boy’s father climbed up to the spot near the top of Cheesecote Mountain, near Haverstraw, N.Y., and discovered a human skull. The coroner determined that the victim was female, about 20, and less than 5 feet tall. A jagged rock that apparently crushed her skull lay next to the pile of bones.
