No excuses here but I’ve said it before and I’ll say it again I have met many of 13-year-old that action dresses like she’s 30
I have considered this a possibility almost from the first. I've seen 12 year old girls that physically appear as fully mature women. This girl, if she really was 14 at the time, might have appeared as a fully developed woman, and additionally may have misled people as to her age.
I have also seen young girls trying to pretend they were adults, so I know this sort of thing happens.
