University of Idaho homicide victim Xana Kernodle's father, Jeff Kernodle, said his daughter had "bruises" on her body indicative of putting up a good fight with her attacker in an interview with an Arizona news outlet.

Xana Kernodle, 20, was killed in the early morning hours of Nov. 13 — along with her boyfriend, Ethan Chapin, and two friends, Madison Mogen and Kaylee Goncalves — in a home on King Road in Moscow, Idaho, near the university. Police have not mentioned any suspects or a motive as of Thursday.

"Bruises, torn by the knife," Jeff Kernodle told Arizona news outlet 3TV/ CBS 5, adding that her injuries showed signs of putting up a fight against her attacker. "She’s a tough kid. Whatever she wanted to do, she could do it,"

He also told the outlet that the door to their home "locks with a number code."

"[W]hen I went up there she, I saw her just a week before that and she changed a lot," Kernodle told the outlet. "She had a life. She got to see what it was like to have a boyfriend you live with. And she really turned around. She was really responsible. Helping him out with his studies and stuff. I was really impressed,"
