Everyone remembers the scene not the title

Trying to find the title of a horror movie. In the last scene or close to it one of the villians goes into the family home and pulls his mother from under the bed. It seems she had no arms or legs. She said something to him about being a good boy and they would start over somewhere else. I think he put her in a suitcase, loader her into an old car and drove away. Anyone have a clue what movie this is from?

Is it The X-Files: ‘Home’ (Season 4 Episode 2)?
