David W. Petitfrere, 32, of Miami, was found dead on July 17, 2009, the victim of a gunshot wound in a homicide that remains unsolved. Authorities suspect the shooting was a targeted attack, but no suspect or clear motive has been identified.

The Miami Police Department and Miami-Dade Crime Stoppers have repeatedly appealed for tips and offered rewards, keeping the file open despite a lack of substantial leads. After more than a decade investigators say there may still be people with knowledge of the incident who have not come forward.

Is there anyone who knew David or who remembers the events around July 17, 2009, who can help investigators?
