Aye, that's the rub with DNA. There could be numerous cases with the same perpetrator DNA, but unless they can match the DNA to a name they have bupkis.

Yep, and it's terribly frustrating for LE and the victims' families when there's solid DNA evidence and no match.

I support the use of familial DNA matching, though it's controversial due to privacy concerns for some.

When male perpetrator DNA doesn't get a hit in the criminal database, LE in a handful of states can search for a possible match to a male family member in the criminal database (it's not technically possible with female DNA yet).

It's helped LE solve of a couple of high profile cases and more states are considering allowing it.
