This is a really interesting question to raise - I think I would be quite relieved that they were dead, too. At least then there's no need to consider the idea of too-lenient jail sentences or gloating in court. And you're right - I wonder how many killers are nervously looking over their shoulders these days? I think genetic genealogy is the best scientific breakthrough since the original mapping of the genome in terms of the difference it has made for law enforcement. Thank you for your thoughtful comment and taking the time to read!
