Deleting a post is one of the great mysteries of DCW... xD
What do you mean? It's possible she was just shrunk months prior to the current plotline. And the APTX is still "not completely developed".
Also, I'd like to bring up a point about the effects of the APTX. Does it shrink you to a set age, or does it subtract a certain number of years from your current age? Will you grow and mature as if it were your real age, or will you be forever stuck there? Since Shinichi and Shiho's ages were pretty close to begin with, it's hard to tell if they're biologically the same age now. However, this girl is in middle school. She's the oldest victim, both prior and after the shrinkage (assuming she's the mother), so is there a difference in how the APTX affects her?
