Storms and tides are uncovering long-hidden human remains on New York’s Hart Island. The island is a place where New Yorkers who have little money when they die have been buried for 150 years. Now, skulls and other bones mark the ground of small piece of land. Pictures of the remains have appeared in news reports for years. So in late April, forensic anthropologists from the city medical examiner’s office visited the island. They collected 174 human bones, which they carefully examined and recorded. Their finds included six skulls, 31 leg bones and many other bones from the head and body. Small red flags marked places along the rocky waterline where remains were found.
