What is a primary reason to use ante-mortem records or DNA comparison in identifications?

• A. To delay the process
• B. To support identification or exclusion by providing reference data
• C. To replace all skeletal analysis
• D. To determine the weather during death

Answer: (B)

Ante-mortem records and DNA comparisons provide reference data that allow investigators to confirm or rule out a potential identity by matching the remains to a real person. Dental records, medical images, scars, tattoos, and other distinguishing features collected before death give a unique pre-death snapshot that can be directly compared to postmortem findings. When a DNA sample from the remains is matched to a known relative or identified individual, identity can be established with high confidence. These tools are used to anchor identification to a specific person and to exclude others when there is no correlation. They do not purposefully delay the process, replace skeletal analysis, or reveal weather conditions; they complement the biological profile derived from the bones and tissues.
