On this day, Aug. 18, in 2005, Dennis Rader — better known as the BTK Killer — was sentenced to 175 years in prison before the possibility of parole.

Between 1974 and 1991 Rader murdered 10 people in Sedgwick County near Wichita, Kan. The serial killer acquired the nickname BTK for his modus operandi: It stands for “bind, torture and kill.”
