I wouldn't say its the worst part but it must be horrific for the parents not knowing where she is. Hopefully he is holding out to see if he gets off with it, once convicted, I hope he tells. I'd use hypnosis on the c**t to find out.
I'd doubt very much hypnosis would work on the c**t. Put him on a lie detector. If you find out he is lying and he won't tell then torture him till he does and if he doesn't remember that means he is f***ing mental so shoot the c**t!!!
