Slight update:- Looks like police divers are still searching and they've just been offered some sidescan/proton mag kit to help look for the body:

I hope this helps locate the boy for the family's sake however I still view this search with the magnatometer as looking for a needle in a haystack. Am I too pessimistic in this case?
