Hello, I'm looking for a movie and hope I'm right asking here. I can only remember one scene, seen it a long, long time ago as a teen, of this movie and it is driving me crazy that I can not find it.

It is an investigative/ action movie I think, a bit like mercury rising. So a cop dude taking care of a kid.

The scene: the kid is sorting paper on the floor of a room, seemingly random letters on them. Then the cop dude and maybe a woman go up some stairs, talking about the kid and they see that the paper is sorted to resemble the face of a woman.

I apologize for the lack of other information or if this is the wrong place to ask. Is anybody able to help me?
