This procedure was used to identify leads, not conclusively prove someone was the killer. For that, they use DNA from the suspect himself.
In this case, an man in Oregon was earlier a suspect, but direct DNA comparison ruled him out.

The prosecution has this mans DNA. His relative's DNA likely matched a lot of people. Obviously, they didn't arrest the entire family. It seems likely that they will collect his DNA and attempt to match it to the DNA in his semen. If they get a match, then there is a high likelihood he is the suspect.
More likely, though, they will get a full confession. Serial killers often love to explain their work and take a lot of pride in confessing, because they're really messed up people.
If you run a 99.99% accurate match against a database with 100,000 people, one of whom is the criminal, you are going to get 10 false positives.
If you're one of those false positives, good luck convincing a jury that the 99.99% accurate test is wrong in your case. There's a reason for why general warrants, and most kinds of fishing expeditions are illegal.
