4.2 Importance of Biological Evidences

1. The identification — the source's determination (the person's-and-body's linking). 2. The scene's reconstruction — the event's biology (the spatter's pattern — the struggle's story; the stains' distribution). 3. The offence's proof — the sexual offence's corpus (the semen-and-DNA); the violence's confirmation. 4. The exclusion — the innocent's elimination (the foreign sample's exclusionary power). 5. The paternity-and-kinship — the civil faces (the succession-and-status disputes — U4.4-and- U5.5's line).
