Question For The Horror Fans

This has absolutely nothing to do with baseball, but a question has been bothering me for a number of years. Many who frequent this site happen to be horror movie aficionados, so I thought I'd ask.

Sometime in the mid to late eighties, I caught a movie on one of the movie cable networks. It was most likely Cinemax, when they used to run a bevy of horror movies.

All I remember of a particular movie is one scene that has stood out in my mind. It featured the killer, in a yellow raincoat walking up the stairs. Along the way, his hand is stuck in gum left on the banister. He grumbles about it and continues back up the stairs.

And that's all I got. That one part of one scene. It's been driving me batty for years! With my luck, it's probably part of the stupidest movie on Earth, but I need to know.

I've had some suggestions over the years as to what it may be. I've heard "Student Bodies", but I have never seen this scene in that movie. I've heard "April Fool's Day". I didn't see it in there either. I've heard "Communion" (AKA "Alice, Sweet Alice" or "Holy Terror"). The only connection to that movie is the raincoat and that was worn by a twelve year old girl in "Communion", so that is definitely not it.

My feeling is that it came from a low budget horror/comedy from the early to mid eighties, but I just don't know. If anyone can help, I would greatly appreciate it!
