David Spence - Texas Conviction: 1984, Executed: 1997
Spence was charged with murdering three teenagers in 1982. He was allegedly hired by a convenience store owner to kill another girl, and killed these victims by mistake. The convenience store owner, Muneer Deeb, was originally convicted and sentenced to death, but then was acquitted at a re-trial. The police lieutenant who supervised the investigation of Spence, Marvin Horton, later concluded: "I do not think David Spence committed this crime." Ramon Salinas, the homicide detective who actually conducted the investigation, said: "My opinion is that David Spence was innocent. Nothing from the investigation ever led us to any evidence that he was involved." No physical evidence connected Spence to the crime. The case against Spence was pursued by a zealous narcotics cop who relied on testimony of prison inmates who were granted favors in return for testimony.
