Human remains are exceptionally valuable in forensic analysis, serving as critical sources of information when identification is unknown or the circumstances of death are unclear. Forensic anthropologists meticulously examine skeletal remains to establish a biological profile, determining the individual's age at death, sex, stature, and ancestral background. They can also identify unique individualizing features such as healed fractures, surgical implants, dental work, or signs of past diseases, which are crucial for matching remains to medical or dental records. Furthermore, bones often retain evidence of trauma (e.g., gunshot wounds, blunt force injuries), helping to ascertain the cause and manner of death. Taphonomic analysis of remains and their context can also provide an estimate of the postmortem interval, or time since death. This comprehensive analysis is vital for identifying victims and advancing criminal investigations.

When conventional identification methods like dental records or DNA fail, facial reconstruction becomes a vital technique. This process aims to create a likeness of the deceased person's face directly from their skull. Forensic artists and anthropologists begin by placing tissue depth markers at specific points on the skull, using average measurements known for the individual's estimated age, sex, and ancestry. Muscles, glands, and fat are then sculpted onto the skull, followed by an approximation of the skin. Features like the nose, lips, and eyes are carefully reconstructed based on the underlying skeletal structure and anthropological data. While not an exact portrait, the resulting 2D or 3D reconstruction serves as a powerful investigative tool, generating public leads and aiding immensely in the identification of unknown human remains.
