But a mother wouldn't be interested in seeing her daughter?

I'm not so far removed from your conviction. It's just that, as long as I don't read or hear about a serial killer who did something similar to what you propose Lechmere did, "just for fun"/"just because he could"/just because he felt to" (take your pick), my view is that he would only have stayed put if he felt he could no longer get away. But I'd agree that we don't know at what point he would have felt that.
