On the night that four University of Idaho students were fatally stabbed in a house near the campus, two roommates began urgently texting each other after one of them saw a masked man moving through the house.

“What’s going on,” one of the residents, Dylan Mortensen, texted to one of her friends upstairs, according to new court documents released on Thursday. The friend did not answer, but she was able to make contact with a downstairs roommate, Bethany Funke. “I’m freaking out,” she texted.

Ms. Mortensen and Ms. Funke — who ultimately were the only survivors of the stabbing spree — began texting back and forth shortly before 4:30 a.m., soon after Ms. Mortensen had seen a masked man walking in the hallway outside her bedroom door.

The texts on the night of Nov. 13, 2022, give new insight into the confusion and fright of the two surviving roommates, who appear to have hunkered down in Ms. Funke’s room until later that morning. Ms. Mortensen called or texted each of the stabbing victims around 4:30 a.m., but received no response. No one called 911 until more than seven hours later.

Ms. Mortensen, who had seen the masked figure in the house, told Ms. Funke by text that “no one is answering” the other roommates’ phones, and she described seeing someone wearing something like a “ski mask almost.” Ms. Funke told her to “run” downstairs to her bedroom so they could be together.

“It’s better than being alone,” she texted.
