Just curious, where do you source the missing child image from? Ask the parents for a picture? Hope they remember which gate/turnstile they entered in, when, and then scrub through the footage for a clear shot of the kid to then search for live?

It would be easier if they went missing at the later half of the game, as you could compare new data with relatively fixed positions from child objects earlier on.
