Good efficient butchery

There's a serial killer roaming about the streets of New York City killing young women. Back then in the early 80s there was approximately 10 murders committed each day in N.Y., so nothing special there. But this maniac who likes to slash young girls carries a duck-sounding voice. Lucio Fulci's perfect real-deal 80s video nasty that is no stranger to gore, sleazy sadism and erotica.
