The print was Grant's, and it was lifted from a CD case, duplicated into ballistics gel using a partially obscured process that included PC board etching and print cleanup in a graphics editor, and successfully opened the fingerprint door lock (as well as logging in to a PC). The narrator in the episode did state that one critical part of the process was omitted to keep that episode from being a HOWTO, but it probably wouldn't take a rocket scientist to figure it out.
