@MadMcGoo Maybe this can be of help with establishing which one to submit and which one not.

"You start by taking the physical descriptors (age, height etc, date of disappearance vs Estimated Date of Death) and look for everything that will DISPROVE the Jane or John is so and so.
Once you can not establish that it is not them, then start to work on the other side, look at the distances, known items of clothing, matching scars, tattoos, etc. The more you find on the plus side, the higher is your probability of a match.
Low is nothing positive, but nothing negative, Medium means things like distance and clothing is close, High is the markers that could be distinctive, things like one leg shorter than the other, unique dental work or tooth structure, etc.
Once you have that, then look at the physical pictures but be careful if you are comparing it to a reconstruction because things like hair line nose, lips, ears, etc may not be accurate.
On a comparison of the photos, look at the ears (almost as good as a fingerprint) jaw line, eye sockets, mouth line, arch of eyebrows, general placement of the eyes to the nose to the upper lip. Most people will look at the general face and say yes, that is him. To get better results, break the face up and examine the pieces."
