Dennis Lynn Rader, a.k.a. "The BTK Killer" or "The BTK Strangler", is an American hebephilic serial killer, family annihilator, and stalker. Rader usually targeted women, though he did kill or attempt to kill men and children on a few occasions. He would wander through Wichita until he found a potential victim and enter their homes through home invasions. The kills were highly premeditated, as he would stalk them beforehand to know when they would come home and who lived with them, bring various items with him to use for the kill and the break-in, like duct tape, rope, and a screwdriver (which he would put in a briefcase or a bowling bag), cut off the phone lines to prevent the victims calling for help, etc.
