Eighteen-year-old Gregory Pena was shot in the chest on a cold December evening in the Claremont section of the Bronx. The shooting happened around 8:40 p.m. on Sheridan Avenue near Marcy Place; Pena walked about two blocks before collapsing at Walton Avenue and Elliot Place. He was taken to Bronx-Lebanon Hospital and died of his wounds.

Investigators tied the killing to a dispute between different groups of young men earlier that day and said the encounter may have been an escalation of that altercation. A memorial of about 150 candles and photographs was placed near the corner where he collapsed. On January 3, 2018, police arrested 19-year-old Agustin Guzman of the Mt. Hope neighborhood and charged him with murder, manslaughter, and two counts of weapons possession; investigators described the shooting as crew-related and suggested a possible gang rivalry motive.

If anyone knew Gregory or witnessed the events that night, please share information that could help the inquiry.
