A few years ago, a man was found dead near a park on the Upper West Side of Manhattan.

The police couldn't identify him.

His body was buried in a pine coffin and a mass grave on Hard Island, a narrow strip

of land in the waters off of New York City.

The only marker was a white post that read Plot 383.

More than a million people are buried in Hard Island, but there are no headstones or

plaques, so it isn't easy to find out who they were.

It's known as a place where people end up when their bodies are unclaimed or when they've

been forgotten, but the man in Plot 383 actually had several people looking for him.

Neil Harris was last seen in Inwood, New York on December 12, 2014.

He was last seen wearing a tan car hard jacket, but I could eat blue jeans, tan work boots

and a backpack.

If you have seen or know, Neil's whereabouts.

This was a missing persons flyer that we made.

And that went out every week, every week like clockwork on Mondays.

And then a year went by, nothing.

And then another year, still nothing.

From radio diaries and radio topia, this is the Unmarked Graveyard, a new series where

we untangle mysteries of people buried in America's largest public cemetery.

Stories about how they ended up there, the lives they lived, and the people they left behind.

Hello.

Hi, baby.
