Dennis Rader was the BTK serial killer who murdered 10 victims in Wichita, Kansas between 1974-1991. He would stalk and gather information about his victims' daily lives before killing them, often by strangulation. Rader had a sexual fetish involving women's underwear and was intelligent yet psychopathic with no remorse. He was arrested in 2005 after resurfacing and confessing to the murders in detail. Rader received 10 consecutive life sentences with no possibility of parole for 175 years.
