Inspired by jlindsey86's thread, need horror movie ID

[deaner33]

Back in the late 80's I used to watch a lot of Best of Sex & Violence videotapes, remember those? There was one clip of a kid hiding in the attic watching some maniac raging right below him. The maniac was a regular guy, not some monster & I think he might have been a escaped mental patient. My memory is that it was on the second floor of a house & the kid was peering through a crack in the attic entrance. I've seen a lot of horror movies, so I don't think it was well known & I'm sorry I don't remember any more of it. Help! It's driving me nuts!
