>> As to its use in a trial, the presence of DNA is often used. There is no reason why its absence cannot be used to establish that certain events didn't happen.

The presence of someone else's DNA (and absence of that of the accused or convicted) has been used as the basis for overturning convictions. But I believe it is correct to say that the mere absence of someone's DNA where it might have been expected has never been used to secure a conviction. Nor should it.

The bottom line is that the absence of DNA isn't exculpatory because you never know with any degree of certainty that DNA should have been at the location that was tested.
