In the late 1980s, counsel investigating his case noted the conflicts among his five confessions and new evidence that suggested he did not commit the crimes. Stab wounds were inflicted by a right-handed person, but Giarratano is left handed. A hair samples and sperm sample that was found on the rape victim did not match Giarratano's, and bloody shoe prints found near the scene of the crime did not match Giarratano's. Nor did numerous fingerprints. The official autopsy report was altered after Giarratano made an official statement.
