James Christopher was 28 when he was fatally shot in Cincinnati, Ohio, on January 22, 2011. Police found him after reports of a shooting in Hamilton County; despite an investigation by the Cincinnati Police Department, the case remains unsolved.

The Ohio Attorney General’s Office has listed the homicide in its statewide unsolved homicides database as a cold case and is asking the public for help. Authorities say even the smallest detail could be important for identifying suspects and bringing justice for James and his family.

If anyone has information about where James was that night, who he was with, or anything unusual in the area of the shooting, please contact the Cincinnati Police Department or the Ohio Attorney General’s cold case unit.
