Dayon Barnes was 27 when he was found shot to death inside a car on North Smallwood Street in Baltimore in the early hours of a Sunday morning in December 2011. He was taken first to Bon Secours Hospital and then to the Shock Trauma Center, where he died of his injuries and the Baltimore Police Department opened a homicide investigation.

Barnes’s killing occurred during a weekend of multiple violent incidents across the city, which kept investigators handling several scenes. Police appealed for tips after the shooting, but no suspects were publicly identified and no arrests have been announced. The case later went cold, leaving the circumstances of his death unresolved.

If anyone recalls seeing activity on North Smallwood Street that weekend or has information about Dayon Barnes’s death, please come forward.
