Dna tests offer deeper examination of accused

Twenty years after DNA fingerprints were first admitted by American courts as a way to link suspects to crime scenes, a new and very different class of genetic test is approaching the bench.

Rather than simply proving, for example, that the blood on a suspect's clothes does or does not match that of a murder victim, these "second generation" DNA tests seek to shed light on the biological traits and psychological states of the accused. In effect, they allow genes to "testify" in ways never before possible, in some cases resolving long-standing legal tangles but in others raising new ones.
