Dennis Lynn Rader (born March 9, 1945), better known as the BTK Strangler or simply BTK, is an American serial killer and rapist who murdered at least ten people in Wichita and Park City, Kansas, between 1974 and 1991. Although he occasionally killed or attempted to kill men and children, Rader typically targeted women. His victims were often attacked in their own homes, then bound, sometimes with objects from their homes, and either suffocated with a plastic bag or manually strangled with a ligature. In addition, he stole keepsakes from his female victims, including underwear, driver's licenses, and personal items.
Rader often sent taunting letters to police and media outlets, describing his crimes in detail. In 2004, after a thirteen-year hiatus, Rader resumed sending letters, leading to his 2005 arrest and subsequent guilty plea. He is currently serving ten consecutive life sentences at the El Dorado Correctional Facility.
