With all the unidentified child does, there should be an easier way to run computer sorts on databases to try to achieve a match. Unfortunately, in many cases, missing children have been murdered.
When websites update their photos of these children with the popular "age progressed" image, rather than including more photos of the child at the age he/she went missing, it makes it harder to match doe cases with missing cases.
Another problem encountered when attempting to make matches, is that some sites (like the Doenetwork) will only put a missing case up after the person has been seven years missing.
