DNA can also be matched using DNA services like 23 and me or whatever. If the shooter or a family member has ever traced their ancestry with that it could be used to catch them

Have they ever actually done that though? I don't think they've ever caught someone because they dropped a pube their aunt took a 23 and me.

All the cops have to do is ask the company. It's like ring doorbells.

You sont even need to have sent them a sample. Tou just need about a dozen distant relatives you have never even heard of submit a sample and the authorities can track you down, like people you only share a set of great-grandparents.
