Maybe the birefringent cellulose material found in her private area? I don't think it was white, tho - think it was clear shellac. Unless there was some white paint that scraped off of the paintbrush or was on the piece of wood found. Otherwise, I know green paint was mentioned.
If Lou was in that session, he's probably talking about his beloved windowsill.
There was green paint on her face...somewhere. That paint was found on the floor right outside the cellar room where the urine discharge was found and the paint tray was located. The washer and dryer were, I don't know, 10 feet or so away.
Something about *that* was white paint on JonBenet's body. This suggestion was repulsive to John ("disgustingly sick") so it can't be paint on the sill.
I just wondered if anyone recalls any reports from way back then about white paint on her body. Maybe someone else will see my post and remember. I couldn't find anything on a google search.
I've been reading that transcript for hours and I'm learning of an awful lot of clues. It's tedious to go through it all but wow, lot's of info that I haven't seen elsewhere.
