What was the killer planning to do with the jigsaw body?

Basically, he was trying to "recreate" his mother.

Near the film's beginning, we see the killer going through a box of items including a photo of his mother, her bloody dress, etc. (In the Spanish language version, we hear a voice-over of a child during this scene saying things like, "Mom, why did you leave me?...Come back!".).

In his twisted mind, he apparently thought that if he obtained the right body parts that would fit his mother's clothing and put them all together, then he could somehow bring her back to life.

Recall toward the end of the movie, the killer discovers that the feet (which he got from the girl he cut in half in the locker room) do not fit his mother's shoes.

That's why he then drugs and attempts to kill Mary Riggs. He needed her legs/feet to complete his "puzzle"!

Hope this helps.


Thanks, and have a great day.

I always assumed he was sick and twisted, and wanted to recreate the woman he lusted for in the puzzle.

But I understand the mother theory. The copy I own is a VHS transfer in a cheap DVD box set, so I will assume it's the cut version, so I don't know if they expanded on the idea.

it was almost forty years since he killed his mother. I don't know why but I think you were supposed to assume this wasn't the first time he did it. In which case, he just got rid of them and then repeats himself again in a couple years.
