Especially as FTDNA, for example, have a large array of settings, which, on one hand, is good for privacy but on the other could make it easy to miss.

I hope they got the right guy for the Golden State Killer and not just some dementia-ridden senior citizen that they could pin it on.

The genealogical genetic tests only let you find a pool of suspects (in this case no more than two dozen men), they’d then be able to a 100% match through standard means. He admitted guilt and pleaded guilty to a number of other crimes that weren’t explicitly linked to him. The only real concern I have about that is whether the police used the threat of the death penalty to get him to help clear a backlog of cold cases that he wasn’t responsible for.
