See - this is what I was thinking about the Sutherland Springs killer.
They could have tried to hook the dead bastard up to a heart lung machine. And artificially created a pulse and blood flow.
But even then - with all the morally and legally questionable obstacles - I doubt that it would work.
Why would it not work? If you take into account all the methods employed by the designer to detect a valid finger print, it would seem to me they could be replicated.
