Suspicious markings on the bones suggested that this body had also been butchered. Anthropologist Douglas Owsley, of the Smithsonian Institution, conducted isotopic tests on the bones, revealing that the skull and leg belonged to an English girl, and the bones' physical characteristics showed that she was about 14 years old when she died. A variety of tool marks in the bone show someone, first tentatively and then forcefully, trying to deflesh her skull. A sharp puncture through the left temple and subsequent cracking show that someone eventually worked up the nerve or strength to pry her skull open. Finer knife marks along the cheekbone and jawline suggest that someone purposefully cut flesh off of the skull.
