2022 University of Idaho killings
The Latah County coroner conducted autopsies on the four victims on November 17. She said they all appeared to have been stabbed multiple times (with fatal wounds in the chest and upper body) with a large knife (if not the same knife, very similar ones). At least one victim (with what were apparently defensive stab wounds on her hands) and possibly more appear to have tried to fend off their attacker, and the victims may have been attacked while sleeping in their beds. None showed signs of sexual assault, and toxicology reports are pending. All four deaths were deemed homicide by stabbing. They were not tied and gagged. No weapon has been recovered, though the police believe the killer or killers used a fixed-blade knife.
