My mind just keeps going back to the list of items found in his home/barn. The underwear. I believe they mentioned women's underwear? If these underwear came from his victims..... I wonder, I know this is sickening, but I wonder if any were a child's/pre teen's size. Many times you can tell by the style and prints on them, what age group may have worn them. Also, there may be good indication as to the age of the underwear, such as dry rotting, yellowing, styles, how they're made, manufacturer, to help create some idea on how long ago some of his victims may have been abducted.
