250-754: A foundation for facial drawings done on transparent vellum. Recently developed, the F.A.C.E. and C.A.R.E.S. computer software programs quickly produce two-dimensional facial approximations that can be edited and manipulated with relative ease. These programs may help speed the reconstruction process and allow subtle variations to be applied to the drawing, though they may produce more generic images than hand-drawn artwork. Three-dimensional facial reconstructions are either: 1) sculptures (made from casts of cranial remains) created with modeling clay and other materials or 2) high-resolution, three-dimensional computer images .

500-440: A set of remains. Through close inspection, the forensic artist can easily approximate the thickness of the soft tissue over the remaining areas of the skull based on the presence of these tissues. This eliminates one of the most difficult aspects of reconstruction, the estimation of tissue thickness. Additionally, any other bodily or physical evidence found in association with remains (e.g. jewelry, hair, glasses, etc.) are vital to
550-541: A unique alternative when all other identification techniques have failed. Facial approximations often provide the stimuli that eventually lead to the positive identification of remains. In the U.S., the Daubert Standard is a legal precedent set in 1993 by the Supreme Court regarding the admissibility of expert witness testimony during legal proceedings, set in place to ensure that expert testimony

This method uses a clay-like substance to recreate the musculature of the victim’s skull and focuses on the insertion of the muscles to the skull. The American Method is a second method of reconstruction however, this technique focuses on the overlying tissue of the skull. This method requires the facial tissue depth data recorded from previous remains or from live patients, using tissue puncture markers and/or ultrasounds. This technique can display
650-470: Is an approximation based on osteological measurements; therefore, distinguishing characteristics used in identification could be missed. The position and general shape of the main facial features are mostly accurate because they are greatly determined by the skull. An image of the forensic model of a Neolithic dog skull found at Cuween Hill Chambered Cairn , Orkney, Scotland was published by Sci-News.com on April 22, 2019. Forensic artist Amy Thornton made
700-405: Is based on sufficient facts or data, derived from proper application of reliable principles and methods. When multiple forensic artists produce approximations for the same set of skeletal remains, no two reconstructions are ever the same and the data from which approximations are created are largely incomplete. Because of this, forensic facial reconstruction does not uphold the Daubert Standard ,
750-440: Is expanded, the likelihood of producing the most accurate reconstruction possible is largely limited. A second problem is the lack of a methodological standardization in approximating facial features. A single, official method for reconstructing the face has yet to be recognized. This also presents major setback in facial approximation because facial features like the eyes and nose and individuating characteristics like hairstyle –
800-462: Is not considered a legally recognized technique for positive identification, and is not admissible as expert testimony. Currently, reconstructions are only produced to aid the process of positive identification in conjunction with verified methods. Two-dimensional facial reconstructions are based on ante mortem photographs , and the skull . Occasionally skull radiographs are used but this is not ideal since many cranial structures are not visible or at
850-934: Is the process of recreating the face of an individual (whose identity is often not known) from their skeletal remains through an amalgamation of artistry, anthropology , osteology , and anatomy . It is easily the most subjective—as well as one of the most controversial—techniques in the field of forensic anthropology . Despite this controversy, facial reconstruction has proved successful frequently enough that research and methodological developments continue to be advanced. In addition to identification of unidentified decedents , facial reconstructions are created for remains believed to be of historical value and for remains of prehistoric hominids and humans . There are two forms pertaining to identification in forensic anthropology : circumstantial and positive . Facial reconstruction presents investigators and family members involved in criminal cases concerning unidentified remains with

Krogman who popularized facial reconstruction's application to the forensic field. Krogman presented his method for facial reconstruction in his 1962 book, detailing his method for approximation. Others who helped popularize three-dimensional facial reconstruction include Cherry (1977), Angel (1977), Gatliff (1984), Snow (1979), and Iscan (1986). In 2004 it
1250-444: The cast in the following order: temporalis, masseter, buccinator and occipito-frontals, and finally the soft tissues of the neck. Next, the nose and lips are reconstructed before any of the other muscles are formed. The lips are approximately as wide as the interpupillary distance. However, this distance varies significantly with age, sex, race, and occlusion. The nose is one of the most difficult facial features to reconstruct because
1300-405: The cast is set, colored plastics or the colored ends of safety matches are attached at twenty-one specific "landmark" areas that correspond to the reference data. These sites represent the average facial tissue thickness for persons of the same sex, race, and age as that of the remains. From this point on, all features are added using modeling clay. First, the facial muscles are layered onto
1350-464: The correct scale. This method usually requires the collaboration of an artist and a forensic anthropologist . A commonly used method of 2D facial reconstruction was pioneered by Karen T. Taylor of Austin, Texas during the 1980s. Taylor's method involves adhering tissue depth markers on an unidentified skull at various anthropological landmarks, then photographing the skull. Life-size or one-to-one frontal and lateral photographic prints are then used as

Most commonly, however, only the bony skull and minimal or no other soft tissues are present on the remains presented to forensic artists. In this case, a thorough examination of the skull is completed. This examination focuses on, but is not limited to, the identification of any bony pathologies or unusual landmarks, ruggedness of muscle attachments, profile of

In biological anthropology , they were used to approximate the appearance of early hominid forms, while in archaeology they were used to validate the remains of historic figures. In 1936, Rose Koller from the Natural History Museum in Vienna led a team of sculptors at the Smithsonian Institution's Anthropological Department in recreating likenesses of "ancient Austrians" from their skulls.

1800-657: The method presented by Taylor and Angel from their chapter in Craniofacial Identification in Forensic Medicine, pgs 177–185. This method assumes that the sex, age, and race of the remains to undergo facial reconstruction have already been determined through traditional forensic anthropological techniques. The skull is the basis of facial reconstruction; however, other physical remains that are sometimes available often prove to be valuable. Occasionally, remnants of soft tissue are found on
1850-483: The nasal spine – down, flat, or up. A block of clay that is the proper length is then placed on the nasal spine and the remaining nasal tissue is filled in using tissue markers two and three as a guide for the bridge of the nose. The alae are created by first marking a point five millimeters below the bottom of the nasal aperture. After the main part of the nose is constructed, the alae are created as small egg-shaped balls of clay, that are five millimeters in diameter at

Forensic experts will use their in depth knowledge of facial musculature and tissue attachments on the skull, in order to recreate the identity of the victim. In order to do such, it is important to consider the appearance of
2150-428: The tissue thickness markers and the ears (noted as being extremely complicated to reproduce) are added. Finally, the face is "fleshed," meaning clay is added until the tissue thickness markers are covered, and any specific characterization is added (for example, hair, wrinkles in the skin, noted racial traits, glasses, etc.). The skull of Mozart was the basis of his facial reconstruction from anthropological data. The bust

Using a calculation of three times the length of the spine plus the depth of tissue marker number five will yield the approximate nose length. Next, the pitch of the nose is determined by examining the direction of

The most pressing issue relates to the data used to average facial tissue thickness. The data available to forensic artists are still very limited in ranges of ages, sexes, and body builds. This disparity greatly affects the accuracy of reconstructions. Until this data
