The autopsies performed on the four University of Idaho students who were butchered to death showed that the killings were “personal” – as the father of one of the victims suggested that his daughter tried to fight off the attacker.
Latah County Coroner Cathy Mabbutt on Thursday confirmed that the cause of death was murder by stabbing.
“It would have had to been a large knife,” she told the Moscow-Pullman Daily News about the murder weapon, which has not been found.
The coroner described the attacks from early Sunday as “personal,” according to Idaho News, which cited a CBS report.
Mabbutt said it was possible that some of the wounds in the bloody rampage were defensive, adding that it was unknown who was attacked first.
