Allan Benn, a 36-year-old father remembered by family as having a big heart, was fatally shot outside a Halloween party at a residence on Barnes Avenue in the Bronx on November 1, 2020. Gunfire erupted outside the gathering and Benn was struck in the neck and chest; emergency responders treated him but his injuries were fatal.

The New York Police Department opened a homicide investigation and detectives canvassed the neighborhood for witnesses and information that could identify the shooter. As of early 2021, authorities had not announced any arrests and said the gunman remained at large.

If anyone was at the party or saw activity on Barnes Avenue that night, can you share what you remember with investigators?
