Carlyle W. Harris
Carlyle Harris was executed by electrocution at Sing Sing prison in New York in May 1893.

His mother and brother attended a private funeral held over his body inside the prison, and he was buried that afternoon. At his direction, an affidavit from one of the jurors in his case was placed in the coffin, and his final written statement, released after the burial, maintained his innocence.
Cause of death, as reported: Executed by the state. Carlyle Harris maintained his innocence in his final statement, and the warden's account reports the execution as successful.
Reported by: Sing Sing prison warden (the agency that held him). The only account of how this person died comes from the agency that held him.
