Will DNA testing eventually tell us what an unknown suspect looks like in a criminal case?

Right now the DNA evidence can be used to determine whether the suspect looks like a woman (X-X chromosome) or a man (X-Y chromosomes). At present only stem cells can be used to clone a person but in the future if differentiated cells could be cloned the evidence could be used to obtain an 'identical' twin except, for the age gap. Few people look like their baby pictures. Although there is no statue of limitations for murder, it is unlikely that criminals would be cloned from the evidence. Also, there should be ethical questions about cloning only a face.

I think DNA analysis will advance to the point of drawing a very accurate picture of the guy that happened to be walking his dog when the murder took place- so it should be every bit as valuable as the way we currently use DNA tests in the courtroom.

Mostly, but if you had 2 people that looked "mostly alike", you wouldn't be able to tell the differance. The dna would only be able to tell what they probably look like.

I don't think so. How could you link someone's DNA with their physical appearance. You might be able to get some other clues though, like what kind of diseases they are prone to.
