Looking for an 80's low budget horror film about a ghost in a cabin in the woods.

In the end we find out the ghost is a little girl who lived there and was murdered. She is buried under the floorboards or in the fireplace with her teddy bear (we see her skeleton).

It has a guy in it that looks like Kris Kristofferson, and there's a slow country song playing during the credits that says 'Amy, where are you? I love you."'

Help. This has been bugging me for years.
