Hector Luis Diaz Jr. was killed in the early hours of November 4, 2015, in his Bushwick, Brooklyn apartment building. At about 1 a.m. he went to the lobby of his Menahan Street residence; a bullet fired through the front door struck him in the head. Diaz was taken to Elmhurst General Hospital and died of his injuries.

He was 35, born in Queens, and a father of two sons, Hector and Benjamin. Friends and family described him as a positive person who often left others in a better mood. The NYPD’s initial investigation treated the shooting as a targeted attack: authorities believe an intruder was trying to break in and that Diaz was shot through the glass door when he went to check the disturbance.

The case later grew cold with no suspects publicly identified and no arrests announced, leaving his family without closure. Does anyone who lived in or around Menahan Street that night have information that could help investigators?
