a couple of pointers: you may actually have to BE a cop or forensiologist (if that's a word) to purchase the software. I'd check into that first.
also, if civilians can in fact purchase it, I bet it's expensive
probably more money than you would want to spend just to see what your neice will look like down the road....
and lastly, those things aren't entirely accurate. they just add wrinkles and add some facial differences (probably uses algorythms or something). I wouldn't trust it. just imagine the neice now, and add wrinkles and a slightly different bone structure
I don't really know of any programs though. sorry.
