Use of facial approximation techniques in identification of Green River serial murder victims

Since 1982, the remains of 41 victims of the Green River Serial Murderer have been recovered. The majority were discovered as skeletal remains, and 24 facial approximations have been used in attempts to develop leads for identification of nine of these victims. Nine different artists were used. Interpretations of the same victim varied greatly. For those victims subsequently identified, resemblance of the facial approximation to the deceased showed considerable variation, but in some cases was quite accurate. This experience created a unique opportunity to compare different methods of facial approximation techniques and artists, and to comment on their efficacy in aiding identification.
