This sounds more like a Charles Dickens novel than it does about a 21st century news story. It seems that millions of formerly impoverished but now deceased citizens, along with many whose bodies were unclaimed by family, are buried in Hart Island. The 101-acre sliver of land in the waters far, far north of the Manhattan is the final resting place of more than an estimated 750,000 deceased persons. Hart Island is not open to the public.
Most of the graves are unmarked. The records of the coffin row-and-column placement are kept between five and 10 years, depending upon the effect of plot soil conditions on attempted disinternments. When disinternment attempts are no longer practical and appropriate, those plot burial records are turned over to the Municipal Archives.
