Movie Hunt - neep Help
 

Hi everyone

I have been looking for this movie quite a long time on internet but i think i need your help to identify a movie i only have few memories from.

The story is about a guy, disturbed since his childhood as his mother would mess with his jigsaw puzzle. This guy become a murderer and cut pieces of women to do a kind of human jigsaw puzzle.
In the last scene, a cop find the "dead" body of the murderer and the very last image is the "dead" body grabbing the cop's nuts.

I have no idea of the title of this movie and if this remind you something, it would be awesome!

Cheers.

edit: sorry i didn't see the post dedicateed to that kind of stuff, i'll post it in there! But i've no idea how to delete this thread.

Uhhhh Peices??? The opening scene has to do with a puzzle and him killing his mother, from what i remember!. Look up the trailer on youtube. Its a great movie, its ben so long.
