When identifying a body, investigators rely on features that remain stable and uniquely distinguish an individual. Dental records are highly reliable because teeth are durable and can be matched to antemortem radiographs and charts. DNA provides a genetic signature that is essentially unique to each person, offering a near-certain identification when a reference sample is available. Fingerprints are another long-standing, distinctive identifier that can be linked to databases and used for verification.

Voice recognition, while useful in other contexts, isn’t used for identifying a deceased person because a body cannot produce a controlled voice, and even with a recording, voice characteristics can vary with health, age, emotion, and recording conditions. There’s no universally robust, postmortem reference standard for voice, making it far less reliable for positive identification than dental, DNA, or fingerprint methods.
