JonBenét Ramsey

All blood evidence, including blood found in underwear worn by the victim, blood on a Barbie nightgown found on the floor next to the body, and blood on a white blanket, was matched to JonBenét's. However, police investigations within and around the residence discovered the following clues which can be interpreted as evidence of intrusion:

•   Two dissimilar footprints in the wine cellar that did not match any of the shoes in the residence
•   A third footprint of an unknown person on the outer part of the window of the room by the wine cellar (John Ramsey said the window was malfunctioning)
•   A possible footprint on a suitcase, placed directly below the same window
•   A rope that was foreign to the residence found on the bed of the guest room near JonBenét's room
•   Physical marks on JonBenét's body suggested the use of a stun gun. There is, however, only one mark on her neck and the use of a stun gun is inconsistent with the mark.
•   A DNA sample on JonBenét's underwear (believed to be saliva) that did not match any known suspect
•   A DNA sample found under JonBenét's fingernails that also did not match any known suspect
