In actuality, one would need to get their hands on new and compelling evidence to apply the technology to. We have more modern cameras, but all they do is capture an image with better and more efficient technology. The end result is the same, it's just a picture open to interpretation. Same goes with sound recording technology. It is captured with better equipment than in the past, but it is still the same sounds, and again, open to interpretation. The only game changer that I see in modern technology is DNA testing. I would say that the old methods of discovery will not change, but if evidence is found, the method of identification will be where modern tech will make the difference.
