When Annette Vega was seven years old, she found out the man she called "dad" wasn't her biological father. But all she knew was that her mom had had a teenage romance with a guy named Angel Garcia. Annette has searched for Angel for more than 30 years. That search is coming to the end."The Unmarked Graveyard: Stories from Hart Island" is a new series from Radio Diaries that tells the stories of seven people buried on Hart Island through a range of circumstances. Hart Island, an uninhabited strip of land off the Bronx in Long Island Sound, is America's largest public cemetery, sometimes known as a "potter's field." Since 1869, more than a million people have been buried on Hart Island, including early AIDS patients, unidentified and unclaimed New Yorkers, immigrants, incarcerated people, artists, and about ten percent of New Yorkers who died of COVID-19.
