investigators also found fibers that contained traces of Gacy’s blood and semen in the same area. Blood belonging to the victims was found on some of the fibers, which would later directly tie Gacy to the crimes. The fibers in Gacy’s car were analyzed by forensic scientists and matched Piest’s hair samples. Furthermore, the search dogs that determined that Piest had been in Gacy’s car in Macbeth icated this by a “death reaction”, which told investigators that Piest’s dead body had been inside of Gacy’s car. Out of Gacy’s 33 known victims, only 25 were ever conclusively identified. Many of Gacy’s victims had similar physical descriptions and were therefore hard to identify by purely asking the public. To identify the victims, investigators turned to Betty Pat Gatliff, a pioneer in forensic science and facial reconstruction. Facial reconstruction is the process of recreating the facial features of an individual by using their remains. Certain facial features, such as jawlines, nasal structure, and overall face shape can be useful in identifying a victim ev Voice within a political and social contexten long after death. By using these features, and with the help of computer software, fo Macbeth rensic investigators are able to create an image of a person’s face, which is instrumental in identifying victims after their bodies have decayed. Facial reconstruction can be done in two or three dimensions. Two-dimensional facial reconstructions is used with skull radiographs and are based on pre-death photographs and information. However, this is not necessar Macbeth ily ideal because cranial features are not always visible or at the right scale (Downing). In order to get a realistic and more accurate depiction of the victim’s face, an artist and a forensic anthropologist are usually necessary (Downing). Three-dimensional facial reconstruction is done by sculptures or high resolution, three-dimensional images. Computer programs are able to create facial reconstructions by manipulating scanned>
