Xana Kernodle, 20, (middle) fought back against her alleged attacker Bryan Kohberger (bottom right) and repeatedly grabbed the murder weapon before her death, sources said. The claims match an earlier report from her father Jeffrey, who revealed in November that his daughter's autopsy said her skin had 'bruises[ and was] torn by the knife.' Kaylee Goncalves, 21, and Madison Mogen, 21 were killed first before the killer attacked Kernodle and Ethan Chapin, 20, (together left). The accused mass murderer was also allegedly seen in the student union 'sitting by himself' weeks before the killings. One student who identified herself as Chelsea, a sophomore, said she saw Kohberger, a student at the nearby Washington State University, eating alone in the food court just weeks before the November 13 slayings.
