Some of the University of Idaho students were "stabbed in their beds" at a rental house last Sunday, a coroner has revealed.
Cathy Mabbutt, Latah County coroner, confirmed the four students were killed with a "large knife" after autopsy reports concluded the victims were stabbed to death in Moscow, Idaho, US.
The victims were stabbed in the chest and upper body, as Moscow Police Department confirmed there were no signs of sexual assault.
