That pic does not look like an adult. I would ever go so far as to say it resembles at young teen.
I also thought it looked like a boy or small woman. That’s probably why they arrested the younger son (13) , but apparently they’re no longer looking at him as a suspect.
Strange story. Orsolya is a Hungarian version of Ursula, although I don’t know if she was actually from Hungary herself or even had any connection with Eastern Europe. Her husband seems to have been involved in Eastern European dealings, FWIW.
