There was a TV movie.."I Know My Name is Steven", good movie about the whole ordeal he went through.
I believe I saw that movie or at least parts of it--somehow I knew about the case. The story is so interesting/odd/amazing, it would make a for a good major motion picture too. I think I remember seeing a Primetime or Dateline about the murdering brother. Gee, what those parents have been through.
it was actually called "I know my first name is Stephen"
