first question: his hands are burned enough so that running his fingerprints isn't advisable, but how bad would the damage be? i don't want him, say, crippled for life, so he has the minimum amount of damage to affect fingerprinting efficacy, but i'd like a realistic idea of what the healing process would be like and how long it'd take, especially if he took off from the hospital soon after and didn't have access to regular medical care. other than his hands, he's in a general state of malnutrition and exhaustion, with a slightly weakened immune system.
second question: with fingerprinting out, how else would the police ID him? dental records? would they draw blood? i was considering the use of DNA, but would the kid be listed in, say, CODIS? he had no reason to be entered in any criminal or tracking databases prior to his running away (and subsequent 'return home,') national fingerprint registry aside. the kid's also trying really, really hard to avoid official attention, as he doesn't want word of his current location getting back to somebody at home; if he had a fake ID on him, would any of this be necessary?
i don't watch enough forensics shows to be able to answer these. XD; googled for fingerprint databases, information on CODIS, runaway youth, and checked the annals of this community (and laughed over the fact that 'destroying the world' is a tag).
thanks in advance!
