A little-known island just offshore from the Bronx in New York City serves a massive cemetery, where around 800,000 bodies have been buried over the past 150 years. <br /><br />Those laid to rest at Hart Island typically are the poor, those without next of kin or the unknown. <br /><br />But thousands are still buried in mass graves there every year, and some have been buried there as a result of bungled paperwork.<br /><br />Only those who can prove they have relatives buried there are allowed to visit the cemetery, and a foundation founded by an artist is helping families locate loved ones on Hart Island. <br /><br />Al Jazeera's Scott Heidler reports from New York City.
