Stephen Doyle was found murdered in Jacksonville, Florida, on February 23, 2008. He was 55 years old. The circumstances of his killing remain largely unclear, and no arrests have been announced.

The Jacksonville Sheriff’s Office includes Doyle’s case among more than 300 unsolved homicides from the city, many dating to the early 2000s. Investigators have reexamined evidence and the department’s cold case unit continues to seek new leads; forensic advances have helped in other files but Doyle’s case still lacks witnesses or solid evidence publicly tied to a suspect.

If anyone has information about Stephen Doyle, his movements before February 23, 2008, or possible witnesses, please share what is known with investigators.
