Errol Marshall III, 19, was found dead from a gunshot wound on a front porch in New Haven shortly after 10:30 p.m. on July 3, 2013. A lifelong New Haven resident born February 12, 1994, Marshall was pronounced dead at the Division Street scene that evening.

Police said Marshall’s killing was connected to another homicide earlier that day: 23-year-old Brian Gibson was shot and killed around 12:30 p.m. on South Genesee Street. Authorities publicly warned against retaliatory violence while investigators pursued leads. An arrest in Gibson’s case came later in 2013 and resulted in a conviction, but no suspect has been publicly identified in Marshall’s death.

A small memorial with candles and messages remains near the porch where he was found. The investigation into Marshall’s homicide remained open and unsolved as of early 2025; investigators continued to seek information from anyone who might help. Did anyone in New Haven see or hear anything on July 3, 2013 that could help this case?
