The killer's plan is to kill all 12 centerfold girls from the magazine's annual issue. He cuts the face out after killing the January and March women. Doing so he inadvertently removes the February and April faces, which are on the reverse sides.
After receiving a phone call from the killer, the Stewardess calls the police and asks for Lt. Garrett, who gave her his contact information. She is told Sgt. Garrett is off today.
