Dennis Rader, known better as the BTK killer, was a serial killer that claimed the lives of 10 individuals over the span of 17 years. His alias, BTK, stood for "Bind, Torture, Kill".
Between 1974 and 1991, Rader would send letters to the police and local news outlets detailing the unfortunate fate of his victims. After a hiatus, Rader resumed sending letters in 2004, eventually leading to his 2005 arrest. Like many killers, hubris was his downfall. After sending a news outlet a floppy disk, police were able to use metadata from a deleted Microsoft Word file to identify him.
Since all of BTK's murder took place in the victims' homes, these following addresses will forever be marred by the heinous acts that took place within.
