Murder Scenes

[Mastamind]

So, I'm looking for scenes of bloody murder, preferably where someone is being butchered with a knife. Ideally, it'd be a man slaughtering a woman. Examples of what I need would be the murder scene from Perfect Blue- the crueler and bloodier it is, the better.
I just read over this post, and almost had a chill run down my spine; but that's what the AMV is supposed to accomplish, anyways. Thanks very much in advance.

Higurashi has this quite a bit, if I recall correctly.

Spoiler :

The dissapierence of Suzumiya Haruhi

Spoiler :

Once again, a girl stabs a boy with a knife and then puts pressure on his would with the back of the knife so he'd suffer some more while lying on the floor trying to not give in to the wound while holding it.

Kara no Kyoukai ep 3

Spoiler :

Right in the beggining of the ep, there's this bunch of guys that first sexually violate this girl and then stabs her with knife... well it looks like it.. but the stabing is shown somewhere in the middle

Kara no Kyokai episode 7 has some pretty interesting final scenes.

If you can find a good source the first episode of Shangusten Tsukihime has one part if edited right may work for you're purpose.

My first thought was Black Butler and the Jack the Ripper episode, but it is a chainsaw not a knife.
