I read this morning that a new technology has come along which allows fingerprints to be lifted from metal surfaces, even when they have been wiped off, and I presume even after 120 years.
This opens some interesting possibilities. The first problem is, what metal objects are still around that Jack might have handled?
Assuming that this problem is solved I am sure that somebody will say, well, so what? You have no database and no suspects to compare the prints to.
First of all it would be interesting just to look at Jack's prints. The way in which he grasped an object at one of the crime scenes might provide a valuable clue.
Secondly, if you find half the pieces to a puzzle, do you throw them away, or do you keep them, hoping that the other pieces will turn up?
Suppose you could match crime scene prints with prints on a teaspoon found in Druitts house, or on Kosminski's manacles from Colney Hatch, or on a tin cup belonging to Barnett?
