Lam Kor-wan was a serial killer from Hong Kong.He worked as a taxi driver and he would pick up female passengers,strangle them with electrical wire,take them to his family home and dismember them.His English moniker The Jars Murderer was coined when the police revealed that he had hoarded sexual organs in tupperware containers.He was a keen photographer and frequently took pictures and video of his victims filming himself performing an act of necrophilia with his fourth victim.The Chinese press nicknamed him "The Rainy Night Butcher" because several of his attacks occurred during inclement weather.Lam was arrested by plain clothes officers on August 17,1982.He had attempted to develop photographs of one of his dismembered victims at a Hong Kong Kodak shop."Hong Kong Butcher" is based on his crimes as is infamous Cat. III classic "Dr.Lamb".Sleazy and nasty movie with few grim scenes of murder and dismemberment.Worth checking out for true crime buffs.
