3D animation gives evidence more bite

摘要

Animated 3D reconstructions of a crime suspect's teeth biting a victim could make forensic bite-mark matching more accurate. Error rates are still too high for definite identification, but the technique could help jurors make their minds up. Forensic bite-mark matching has come in for severe criticism. A handful of recent murder convictions in the US that relied on bite-mark evidence were overturned after DNA evidence came to light. And previous research has shown that even under ideal conditions matching bite marks is fallible (New Scientist, 13 March 2004, p 6).
