Robert Haughton was 45 when he was shot multiple times in Philadelphia on the evening of Saturday, January 29, 2011, and died of his injuries. Police responded that night and launched an investigation, but the case grew cold as investigators lacked substantial leads and crucial evidence to identify a suspect.

More than a decade later the case remains open but inactive; no arrests have been made and no suspects have been publicly identified. The unresolved homicide has left Haughton’s family without answers and the matter among the city’s unsolved murders.

If anyone has information about Robert Haughton’s death or remembers events in Philadelphia on January 29, 2011, please share what you know.
