Per Kirk's Affidavit:
"The bedroom in which the murdered body of Marilyn Sheppard was found is shown in approximate scale diagram in accompanying photograph No. 1. The diagram represents the condition at the time it was examined by the undersigned. The two twin beds and bureau, shown in the drawing are in the same position as indicated in prosecution photographs. The drawing omits the rocking chair in the northeast corner of the room, which carried no visible blood or other significant evidence, and the small telephone stand between the two beds which did not figure in testimony, or in this investigation."
