I'll give you a heads up! They won't release the data....assuming they even have it. This is a bogus issue. A lost kid occurs each and every time a change of address form is NOT filled out.
Assuming they stay in the state, they pop up again when they re-apply for benifits. Those that donot usually have re-located elsewhere or no longer qulify for benfits or have changed their name to one of their numerous alias's.
