I’m writing up an MP case of a 27-year-old woman who disappeared, and the most recent picture I have for her is from around age 14 or 15. It’ll have to do. If I myself am anyone to judge by, you can recognize a 27-year-old from a photo of them at 14. I don’t have any photos of myself at 14 handy, but I do have this pic of me at 16, and this one from last month. I look about the same. I think this is easier with women than men, since with men you also have to factor in facial hair and also male pattern baldness.
I do, however, hope a more recent photograph pops up eventually.
