The deaths have been classified as suspected homicides, according to police in Moscow, a college town in north-central Idaho.
The bodies of the students from the University of Idaho were discovered on Sunday after police responded to a report about an unconscious person, the city administration said in a statement, Al Jazeera reported.
No additional details were available, including the cause of death.
All classes for Monday were canceled, the university said, and are set to resume on Tuesday.
Soon after the bodies were found, the university alerted students to shelter in place for about an hour until police concluded that there was no threat to others in the area.
Police in Moscow were seeking information from the public for the ongoing investigation.
