There are crime scene photos that show a fairly large urine stain. I don't know the amount, but pictures show much more than a few drops. It looks significant...like a full bladder release from a child.I'm fuzzy on the case now, but I think the section with stain was covered by the paint tray, wasn't it? And I don't think the stain was very big; I was under the impression that it was more like a drop. But I could be wrong.
