INFO:

The BTK killer's penchant for bondage is evident in the moniker he gave himself. The letters BTK stand for "Bind, Torture, and Kill" and accurately describe Dennis Rader's method for killing 10 people in Wichita, Kansas over three decades. For Rader, his greatest pleasure was never derived from the kill itself, but came from the bondage and torture that he inflicted on his victims before their death.
