Johnny Duncan, a 49-year-old African American man, was found fatally shot inside a home in the Moncrief area of Jacksonville, Florida, on July 2, 2018. His death was reported after a 10-year-old child called 911 to report a shooting. The Jacksonville Sheriff’s Office opened a homicide investigation and treated the circumstances as suspicious.

Investigators faced challenges early on, including a lack of immediate witnesses and concrete leads. No arrests or suspects were publicly identified as the investigation continued. The case remained open in subsequent years, with law enforcement periodically revisiting leads and urging the community to come forward with information to help identify those responsible.

If anyone knew Johnny Duncan, saw or heard anything in Moncrief on July 2, 2018, or has information that could help the investigation, please share what is known.
