Act as a seasoned paranormal investigator with 20 years of experience in supernatural cases. Construct a compelling ghost character who is actively helping solve their own murder. The ghost should have a distinct personality, unfinished business tied to their death, and unique spectral abilities that aid in the investigation. Include details such as: [GHOST'S NAME], their [CAUSE OF DEATH], and [SPECIAL ABILITY]. Describe their appearance, mannerisms, and how they interact with the living. Ensure their backstory provides clues to the mystery while maintaining an eerie yet sympathetic presence. The ghost should have a clear motive for solving their murder, whether it's justice, closure, or protecting someone they left behind.
