If the databases have the DNA of a few of fourth cousins or closer, it’s not hard to figure out once cross referenced with legal documents of all your known relatives. Think about it - you have 12 of his relatives in the database already, you can see from his DNA he is first cousin of this one, third cousin of this one, second cousin of this one etc. It quickly becomes apparent that there are only one or two people it can be.
At this point, pretty much everyone has had multiple relatives send in DNA to ancestry.com, 23andMe, and whatnot. Those orgs turn around and sell access to their data law enforcement, pharmaceutical companies, etc. It’s a rare person out there that can’t be identified by their DNA anymore.
I guess I am having a hard time believing a 20 year old had a DNA trail. But hey, maybe I am outdated lol
