Identification of the dead and disaster victim identification
Scientific identification rests on three primary identifiers — fingerprints, dental comparison and DNA — and on secondary identifiers such as medical implants, old fractures and tattoos; visual identification by relatives is unreliable in damaged bodies and mass disasters.
Why it matters in the exam
The exam asks what the primary identifiers are, how sex, age and stature are estimated from a skeleton and what the stages of disaster victim identification (DVI) are. In a skeleton, sex is best determined from the pelvis, then the skull. Age in children and young adults is set by tooth eruption and fusion of growth plates, the last epiphysis to fuse being the medial (sternal) end of the clavicle, around age 25–30; in adults the pubic symphysis face, the sternal end of the fourth rib and degenerative changes are used, and cranial sutures are less reliable. Stature is estimated from long-bone length, mainly the femur, with population-specific formulas.
Radiological comparison is a strong identification tool: a postmortem radiograph is compared with one from life — the frontal sinus pattern, implants, screws and fracture fixation, and unique bone structure. Many medical implants carry a serial number. Dental comparison relies on dentist's records: fillings, crowns, extractions and broken teeth. DNA is compared with a sample from a personal item, such as a toothbrush, or with first-degree relatives.
In a mass disaster the DVI process has four phases: scene work, postmortem data collection, antemortem data collection from families and doctors, and reconciliation by an identification board. The rule is that no body is released on visual identification or personal effects alone, because clothing and documents can move between bodies. In a burned or decomposed body, fingerprints and outward appearance are sometimes destroyed, so teeth, DNA and radiological comparison are the mainstay.
Key points
- Primary identifiers: fingerprints, teeth and DNA.
- Sex: pelvis, then skull.
- Age: growth-plate fusion; last — the medial clavicle.
- Radiological comparison and implants are strong secondary identifiers.
- DVI: scene, postmortem, antemortem, reconciliation.
Summary table
| Identifier | Type | Strength | Limitation |
|---|---|---|---|
| Fingerprints | Primary | Fast and cheap | Needs records from life; destroyed by fire and decay |
| Dental comparison | Primary | Resists heat and decay | Needs dental records |
| DNA | Primary | Possible from almost any tissue | Relatively slow; needs a reference sample |
| Radiological comparison and implants | Strong secondary | Frontal sinus and serial numbers | Needs a radiograph from life |
| Visual, tattoos, effects | Secondary | Available | Unreliable alone in a disaster |
