Nelson Mattocks, 49, was fatally shot in the face on August 19, 2022, behind the Saint Mary’s Park NYCHA development in the Bronx, where he worked for the New York City Housing Authority. The killing devastated colleagues and residents who knew him as a public servant and a familiar presence in the neighborhood.

The New York Police Department investigated and arrested a 16-year-old male in connection with the shooting; his name was not publicly released because of his age. He was charged with murder, manslaughter, and criminal possession of a weapon. Motive for the attack has not been made clear and few details about the circumstances leading up to the shooting have been released.

Did anyone who lived or worked around Saint Mary’s Park in August 2022 see or hear anything that could help fill in what happened that day?
