My problem is that I agree with Barto, but as the father of two daughters (and two young grandsons) there's the problem of the "victim" and their families.
I honestly don't know how I'd act if given the scenario, but I feel like there would come a time where I'd have to consider it. Dave mentioned the Gabby Petito case, and that's a good one, but I was thinking of that beautiful (in spirit, I'm not commenting on her looks) girl from Alabama that disappeared from Spring Break (Natalee Ann Holloway), and it took eighteen years - 18 - to get any semblance of closure to the story, and even then... the "closure" is a proffer letter (a device by which prosecutors can get information on a crime in exchange for some promise of leniency or immunity) from the primary suspect, but no evidence of any body or forensic evidence.
I would hope my kids aren't animals in that way, but if they were, I don't think I could live with myself in that situation (the primary suspect's father is, if I recall, a judge).
