Robert Earl Hayes
Gresham's Law in reverse: Good science drives out bad
Robert Earl Hayes was sentenced to death for the rape and murder of a 32-year-old woman who worked with him at a horse racetrack in Broward County, Florida.
The conviction rested in substantial part on the testimony of a witness who claimed to have seen Hayes with the victim and heard her reject his advances shortly before the murder.
In addition, the prosecution presented a DNA analysis purporting to link Hayes to the crime. However, the defense attacked the forensic analysis as sloppy and established that several light-colored hairs had been found in the victim's hands. These could not have come from Hayes, because he was African American.
The Florida Supreme Court ordered a new trial on direct appeal in 1995, holding the allegedly incriminating DNA unreliable.
New DNA testing was conducted with proper controls. It exonerated Hayes, but the prosecution refused to drop the charges. Hayes was acquitted upon retrial in 1997.
