Peter Whelan (19) went behind a bar counter in his local pub in Cork and attempted to smash a glass ashtray on a barman's head. After being thrown out of the pub, he went home, collected a couple of knives and left his house in a murderous mood. He picked a house at random and entered via the backdoor. Nichola Sweeney (20) was in her bedroom with her best friend Sinead. Peter entered the room, took the knives from under his top and launched a violent assault on her friend Sinead, stabbing her so ferciously, over 20 times, that he broke one of the knives. He then lunged at Nichola and stabbed her 11 times, finally killing her by stabbing her in the heart. Sinead, despite her injuries had crawled downstairs and hidden in a toilet. Peter Whelan left the house, assuming she was dead. Sinead gave a perfect description to the police and he was arrested.
