3. Lucker (1986)
John Lucker is the inmate of a secure mental home. His crime? He killed and raped the bodies of eight women. He manages to escape the home by killing the orderlies and when he is loose, he hears on the radio that Cathy Jordan - one of his victims managed to survive the attack. This infuriates Lucker so he goes on a mission to find her. He winds up at her old address which is now inhabited by a prostitute. Lucker chats up the prossie and says he will give her business. Upstairs we go in the apartment, and it takes Lucker approximately two seconds to kill the woman. He sets up base in her apartment. The vomit inducing scene comes one month after Lucker has killed the prostitute. He takes off the sheet on the bed where she has been lying and has his wicked way with her severely decomposed corpse. The sight of Lucker's flabby buttocks pumping away on the poor rotten woman is a terrible thing to behold and may also make you lose your lunch. There is just no need for the scene other than to provoke mass vomiting. There's no need!
