In the summer of 1984 a serial killer was on the loose in Los Angeles. Richard Ramirez or the ‘night stalker’ as he would come to be known, broke into people’s houses as they slept and then proceeded to rape, torture and murder whoever was inside. He would sometimes draw satanic pentagrams on the victims’ bodies, and use their own blood to write messages on the wall.During his trial, Ramirez gained a large group of admirers, so-called ‘murder-groupies’. He would go on to receive hundreds of letters while in prison and even got married while on death row. Ramirez is not alone in getting this kind of romantic attention. Cult leader Charles Manson, Norwegian mass murderer Anders Breivik and Danish killer Peter Madsen have all received fan-mail.On this episode of Bad People, presenters Julia Shaw and Sofie Hagen uncover why some women seek out romantic relationships with men who have committed horrific crimes.Warning: This episode contains strong language and references to sexual violence, Satanism and murder.Archive credits: This episode includes audio from DailyMotion, NBC Universal and KRON4.CREDITS:Presenters: Dr. Julia Shaw and Sofie Hagen Producer: Louisa Field Assistant Producer: Simona Rata Music: Matt Chandler Series Editor: Rami TzabarCommissioning Producer: Hannah Rose Commissioning Executive: Dylan Haskins Commissioning Editor: Jason PhippsBad People is a BBC Audio Science Production for BBC Sounds #BadPeople_BBC
