The Invisible Man Strikes! 20

The Invisible Strangler enjoys playing around with Heidi, grasping and groping, throwing her around and beating her down. Poor girl isn't very perceptive and it takes her a while to understand what is happening to her as the Invisible Strangler beats and fondles her. Once he's had his fun, he finishes the job, throttling Heidi to death. Her eyes roll then she goes limp forever.
